Earlier this month, the science community was abuzz with news of a possible breakthrough: a substance called LK-99 that’s alleged to be a room-temperature superconductor. Discovered by Lee Sukbae and Kim Ji-Hoon from Korea university, the material would be a game changer for everything from power delivery to super computers, if it works as advertised. However, after a number of scientists tried and failed to reproduce Lee and Kim’s’ findings, the world seems to have moved on. 

But the field of superconductors is a fast-changing one. Newly-published, pre-print theoretical research generally continues to support LK-99 as having the properties required to become a superconductor; and now, internet sleuths have discovered a Korean-language update on the original LK-99 patent. This document presents further details (and also new questions) regarding the synthesis process, even as the original Korean authors reaffirm the significance (and veracity) of their discovery.

Unfortunately, what we’re still left with is an incomplete picture of LK-99 – one that will seemingly require much more effort in understanding than some would lead us to believe. But the paper does have what’s required: a graph plotting LK-99’s resistivity. Crucially, the graph says it does drop to zero.

Let’s start with the updated patent itself, which describes two techniques to synthesize the relevant, superconducting bits in LK-99. One of those techniques is one we know already: solid state synthesis is the process we followed across the internet, and the one being used by most scientists attempting to replicate the original paper’s really bad recipe. It involves reacting the different compounds within LK-99 in order to obtain a crystal-like final compound of copper-doped lead apatite (mixing lanarkite and copper phosphide, themselves compounds made from reacting lead oxide with lead sulfide and reacting copper with phosphorous, respectively).

There were already a number of problems with the actual recipe, but the updated patent throws yet another wrench in the equation by suddenly including Si (the silicon we know and love) within the mixture. It’s also unclear how silicon got there and how relevant it is for the superconduction itself (if it’s relevant for that at all, which currently doesn’t seem like it is). There does seem to be a pattern in which the original Korean team led by Lee Sukbae isn’t able to provide good documentation. In fairness, it’s also possible that crucial details are simply lost within the bowels of machine translation, or to the speed at which they’ve seemingly put everything together.

At the same time, the authors admit that yes, the resulting lead-apatite compound is typically an insulator (which prevents electrical current from coursing through it, the exact opposite of what we’re trying to achieve here). But they also reiterate that copper doping – which leads to lead atoms being replaced with copper atoms within LK-99 – is key to unlock the claimed superconductivity capability (oxygen atoms are also important, it seems). We already covered this possibility in more detail here, as well as the issue with yield (the proportion of  superconducting material produced through the synthesis process). According to the updated patent, Lee’s team saw samples with a ratio of 48.9% superconductive lead apatite; 40% of non-superconductive lead compounds; and copper compounds (11.1%).

This coexistence between superconductive and non-superconductive compounds may be the reason why certain LK-99 internet videos (if legitimate LK-99) showcased a phenomenon dubbed flux pinning, where external magnetic fields are able to penetrate the superconductor compound through the parts of it that aren’t superconductive (everything that isn’t lead-apatite), pinning it in place.

But it seems that solid state synthesis wasn’t how Lee’s team discovered the (alleged) emergent superconductivity of LK-99. This was done through a technique known as vapor deposition; through it, the same compounds were reacted, but instead of the objective being to end up with an LK-99 crystal, the technique instead allows for the reaction’s vapors to collect against a glass structure, creating a thin film of the compound. According to Sukbae and his team, this film is forged in the 100 degrees Celsius – 400 degrees Celsius temperature range (with a black film of lead sulfide (PbS) in the lower temp area, a white film of lanarkite (Pb2SO5) in the higher temp area, and a gray film of lead appatite in the intermediate area.

It’s from this gray lead-apatite, micron-thick film that the authors insist room-temperature, ambient-pressure superconductivity emerges. The authors also pre-emptively refer state that impurities of iron (Fe) and other elements also emerge from the synthesis process, and that these impurities are well-known sources of ferromagnetism and diamagnetism – some of the features other studies have already encountered and replicated. 

But  it may have been premature to consider those results as proof that LK-99 is a dud. According to the authors, these magnetic features make it more difficult to see the actual Meissner Effect in action, with less cautious onlookers assuming that LK-99’s levitation capabilities ended at those types of magnetism.

The precise method to identify and measure the Meissner Effect’s telltale repulsion of external magnetic fields lies in applying a very low magnetic field with what’s called a Superconducting Quantum Interference Device (SQUID). If done while heating and cooling LK-99, the SQUID will then be able to detect the Meissner Effect as it emerges within LK-99’s superconducting state: within two of its three critical temperature phase transitions. These phase transitions themselves correspond to changes in the material’s structure that then allow superconductivity (the ordered and resistivity-less movement of electrons) to occur.

Which brings us to the latest paper from Vayssilov et al at Sofia University, which also suggests that LK-99 could have the required properties to become a superconductor (do note that once again, there’s no mention of room-temperature or ambient-pressure). The general idea presented in the paper is that there are two ways that could happen: by removing certain oxygen atoms from their places, potential highways for superconductivity appear, with space that was previously occupied by atomic nuclei now being open for electron pairs (the so-called Cooper pairs) to skirt around. Another proposal from the paper is that this same effect can be achieved through the Cu doping we’ve talked about.

Following this LK-99 saga, there’s also been a few articles posted to Arxiv that don’t necessarily deal with LK-99 itself, but with certain systematic errors and incomplete knowledge on magnetism surrounding superconductor research and the theory applied to reach (supposedly correct) results. 

The authors say that they have run LK-99 through a scanning electron microscope in all of its phases as they occur in both production outputs (the film from vapor deposition and the compound from solid state synthesis). According to them, it’s easier to measure and replicate LK-99’s superconductivity results in the film-like material. 

With the authors’ description of how to detect the Meissner effect now published, additional researchers may apply this new knowledge to their replication attempts. Whether or not that will result in any positive replications – and whether that will come sooner rather than later – remains to be seen.

Nvidia, which just earned over $10 billion in one quarter on its datacenter-oriented compute GPUs, plans to at least triple output of such products in 2024, according to the Financial Times, which cites sources with knowledge of the matter. The move is very ambitious and if Nvidia manages to pull it off and demand for its A100, H100 and other compute CPUs for artificial intelligence (AI) and high-performance computing (HPC) applications remains strong, this could mean incredible revenue for the company.

Demand for Nvidia’s flagship H100 compute GPU is so high that they are sold out well into 2024, the FT reports. The company intends to increase production of its GH100 processors by at least threefold, the business site claims, citing three individuals familiar with Nvidia’s plans. The projected H100 shipments for 2024 range between 1.5 million and 2 million, marking a significant rise from the anticipated 500,000 units this year. 

Because Nvidia’s CUDA framework is tailored for AI and HPC workloads, there are hundreds of applications that only work on Nvidia’s compute GPUs. While both Amazon Web Services and Google have their own custom AI processors for AI training and inference workloads, they also have to buy boatloads of Nvidia compute GPUs as their clients want to run their applications on them. 

But increasing the supply of Nvidia H100 compute GPUs, GH200 Grace Hopper supercomputing platform, and products on their base is not going to be easy. Nvidia’s GH100 is a complex processor that is rather hard to make. To triple its output, it has to get rid of several bottlenecks. 

Firstly, the GH100 compute GPU is a huge piece of silicon with a size of 814 mm^2, so it’s pretty hard to make in huge volumes. Although yields of the product are likely reasonably high by now, Nvidia still needs to secure a lot of 4N wafer supply from TSMC to triple output of its GH100-based products. A rough estimate suggests TSMC and Nvidia can get at most 65 chips per 300 mm wafer.

To manufacture 2 million such chips would thus require nearly 31,000 wafers — certainly possible, but it’s a sizeable fraction of TSMC’s total 5nm-class wafer output, which is around 150,000 per month. And that capacity is currently shared between AMD CPU/GPU, Apple, Nvidia, and other companies.

Secondly, GH100 relies on HBM2E or HBM3 memory and uses TSMC’s CoWoS packaging, so Nvidia needs to secure supply on this front as well. Right now, TSMC is struggling to meet demand for CoWoS packaging.

Thirdly, because H100-based devices use HBM2E, HBM3, or HBM3E memory, Nvidia will have to get enough HBM memory packages from companies like Micron, Samsung, and SK Hynix.

Finally, Nvidia’s H100 compute cards or SXM modules have to be installed somewhere, so Nvidia will need to ensure that its partners also at least triple output of their AI servers, which is another concern.

But if Nvidia can supply all of the requisite H100 GPUs, it certainly stands to make a massive profit on the endeavor next year.

The Samsung 990 Pro, one of the best SSDs, was launched last year in 1TB and 2TB flavors. Making good on its promise to release a 4TB version, Samsung has confirmed on X (formerly Twitter) that the speedy PCIe 4.0 SSD will hit the market soon.

Samsung’s position on PCIe 5.0 SSDs is a bit complex. While the company has some enterprise drives that leverage the PCIe 5.0 interface, it has yet to launch a consumer PCIe 5.0 SSD. The Samsung 990 Pro, an M.2 2280 drive, is still on the PCIe 4.0 interface and is currently the brand’s fastest consumer drive. The company has followed up with a 4TB variant, doubling the Samsung 990 Pro’s 2TB capacity. Samsung doesn’t always offer the 4TB capacity with all its SSDs. For example, the Samsung 980 Pro, the predecessor to the Samsung 990 Pro, maxed out at 2TB.

The Samsung 990 Pro 4TB will arrive in a bare drive (MZ-V9P4T0BW) and heatsink (MZ-V9P4T0CW) versions. The SSD’s form factor and design allow it to live inside many devices, including laptops, desktops, and consoles like the PlayStation 5. Therefore, the Samsung 990 Pro 4TB isn’t just an SSD for PC consumers. It’s a drive that PlayStation 5 owners can look forward to due to its ample capacity and blistering performance.

While the manufacturer hasn’t listed the Samsung 990 Pro 4TB on its website, the drive is already mentioned in the product brochure. Similar to the other capacities, the new Samsung 990 Pro 4TB utilizes Samsung’s in-house Pascal SSD controller, which features an Arm design. The company produces Pascal on the 8nm process node. As for the NAND, the drive employs the same Samsung 176-layer TLC NAND as the other drives. The difference is that the die sizes are larger to hit 4TB.

Samsung 990 Pro Specifications

The Samsung 990 Pro 4TB SSD’s advertised performance mirrors that of the lower capacity 2TB version. The drive delivers sequential read and write speeds, hitting 7,450 MB/s and 6,900 MB/s, respectively. Meanwhile, the random performance is at 1,400,000 IOPS reads and 1,550,000 IOPS writes. The figures may look low compared to the PCIe 5.0 standard, but the Samsung 990 Pro can hang with some PCIe 5.0 drives on the market.

Besides the capacity, the difference between the 4TB and 2TB models is the size of the cache memory and the endurance. The Samsung 990 Pro 4TB has a 4GB LPDDR4 DRAM cache and a 2,400 TBW rating, twice that of the Samsung 990 Pro 2TB. As expected, Samsung backs the Samsung 990 Pro 4TB with a limited five-year warranty.

Pricing on the Samsung 990 Pro has improved significantly over the last few months. The 2TB bare drive had a $289.99 MSRP but retails for as low as $169.99 nowadays. The heatsink versions are typically more expensive than the bare drive models and have identical performance. The MSRP for the Samsung 990 Pro 4TB is unknown, but it shouldn’t remain a mystery for long since Samsung has already started teasing the upcoming SSD.

A recent MSI YouTube video meant to be kept private was accidentally leaked, revealing confidential specifications of Intel’s upcoming Raptor Lake Refresh CPU lineup that will vie for a spot in our list of Best CPUs coming soon. The internal video, which reads “NDA, do not share!” has since been taken down, but was up long enough for us to take a screenshot of the video’s key takeaways. The video confirmed what we already know about Raptor Lake Refresh, including its minute performance jump over 13th Gen Raptor Lake, and a minor change in core count on the Core i7 model.

MSI’s leaked video confirms what we’ve known already about Raptor Lake Refresh, the new CPU lineup will be codenamed Raptor Lake-S Refresh and will feature no architectural changes compared to Raptor Lake or Alder Lake — relying on the same Intel 7 process. MSI’s Average performance estimation confirms that Raptor Lake Refresh chips will only have a 3% faster performance advantage over 13th Gen. There’s also lack of any core count upgrades on most chips.

The only exception to this is the i7-14700K which gets a slight core count improvement over its predecessor the i7-13700K. Core count changes go from 8P cores and 8E cores to 8P cores and 12E cores on the 14700K, giving the newer chip four additional E cores over the 14700K. According to MSI, the additional cores give the 14700K 17% more multi-core performance on average.

Raptor Lake Refresh will be the next CPU generation to succeed Intel’s current lineup of 13th Gen Raptor Lake processors. It seems Intel’s plan was to initially launch Meteor Lake as the successor to Raptor Lake (Raptor Lake Refresh is not listed in Intel’s original Meteor Lake slides) and has instead opted to release a refresh of Raptor Lake (which is in and of itself a refresh of Alder Lake) to take its place.

The good news is that Intel’s 14th Gen Raptor Lake Refresh parts will be compatible with current LGA 1700 socket motherboards, and won’t require new motherboards to support the new lineup. In fact, it seems very likely that Intel will not release a new motherboard chipset generation this time around, which will make the current generation 700 series chipset motherboards the primary and only platform for Raptor Lake Refresh if true.

With a rumored release date of October for these new chips, we won’t have to wait long before Raptor Lake Refresh arrives in reviewers’ hands.

Keyboards and key switch maker Cherry today announced its MX2A mechanical switches. The new switches indeed look like a significant rework of the full-sized MX switch, with improvements to many key facets including: smoothness, lubrication, debounce time, and guaranteed lifespan “exceeding 100 million clicks for select switch types”. Cherry also launched the XTRFY K5V2 keyboard, which serves as a platform to showcase the new MX2A (red) switches.

Cherry produces some of the most popular mechanical key switches for PC keyboards. However, in the last few years there have been some notable challengers and upstarts delivering compatible switches with certain refinements and advantages compared to the Cherry originals; the introduction of the MX2A design looks like a concerted effort for Cherry to re-establish a lead.

Today, Cherry is attempting to reclaim its hegemony of the PC keyboard switches market. Changes include:

• Application of high-precision ring lubrication for smoothness, stability and removal of any scratchiness
• A new barrel spring design to ensure the spring maintains its original form better
• Cherry’s updated stem geometry is claimed to improve key press consistency, stability an precision
• Optimized sliding surfaces within the switch. In particular advanced stem guidance is claimed to ensure steady, non-scratchy actuation.

Important features that are retained from previous designs are the switch to PCB connections (3- and 5-pin variants will be available), the “industry leading” gold crosspoint contacts, and the standard cross keycap fit.

Taken together the above improvements plus retention of best in class tech means users can expect benefits to actuation, debounce, operation, noise, and reliability / endurance. The new “lifespan exceeding 100 million clicks,” leapfrogs many rival designs which had outgunned the original Cherry MX switches durability claims (50m).

Cherry hasn’t gone a million miles away from its long-lasting key switch design with the MX2A design. It hasn’t created a new optical or hall effect, for example. But many small and thoughtful changes to its long enduring design might pay dividends for keyboard enthusiasts. We’ll have to go hands-on with the switches to be sure.

Cherry XTRFY K5V2, a 65% Mechanical Gaming Keyboard

Cherry has also launched the Cherry XTRFY K5V2 keyboard with these MX2A (red) switches as a pre-install option. The product page is live, and you can see it is a pretty standard looking 65% design with RGB LED illumination. Potential users will be happy to read that the installed MX2A reds are hot swappable, and the more graceful new switches should feel at home in this double layer foam sound dampening keyboard.

On the product page, Cherry’s XTRFY K5V2 keyboard is configurable with MX2A switches and is listed as “coming soon” at $149. Clicking into the customize options, it looks like you can also choose MX2A switches with Blue (clicky) Brown (tactile) and Black (linear) characteristics, too. Stock will be ready by “late 2023,” according to the product page.

Maker and developer Pixelpanic is a fan of UK departure boards and recently decided to make one of their own at home. Using our favorite SBC, the Raspberry Pi, Pixelpanic has brought the knowledge of arrivals and departures at your fingertips—literally. This departure board small enough to fit in your hand as this project uses a Pimoroni Badger 2040 W as the main board. It’s aided by a Pico W that handles some of the extra data processing used to update the departure board.

The idea behind the project wasn’t to replicate the UK departure boards to a tee but rather display the same information in a format suitable for the Badger 2040 W. This particular display board was chosen because of its E ink panel. This makes it both an affordable and energy efficient option compared to something like an LCD or OLED screen.

According to Pixelpanic, most of the UK departure boards have a similar format in which the data is laid out in a fairly consistent manner. This is because they all use the same API that Pixelpanic is actually tapping into for this replica. The data is presented in this project with a format similar to their local station.

Image 1 of 2

It doesn’t take much hardware to recreate this project, but it does take a bit of ingenuity to put it together efficiently like Pixelpanic has done. While the project relies on a Pimoroni Badger 2040 W,i t’s aided in part by a Raspberry Pi Pico microcontroller which helps with processing data from the API.

The API used to gather departure data in this project is the National Rail Enquiry DARWIN API. The Pico is responsible for gathering data from this system and processing it for the Badger 2040 W. With the data consolidated, it’s processed for formatting onto the eInk display. Pixelpanic was kind enough to provide a complete breakdown of how this system goes together over at their official blog.

If you want to get a closer look at this Raspberry Pi project, check out the project page shared to Pixelpanic’s website. There are plans in the works to possibly redo this project with a larger E Ink display with colors, so be sure to follow them for future updates.

Nvidia this week posted its all-time-record revenue of $13.5 billion as sales of its gaming hardware exceeded expectations, while sales of its compute GPUs for data centers exceeded $10.3 billion — more than double the previous quarter — and demonstrated the roaring success of the company’s A100 and H100 processors for artificial intelligence (AI) and high-performance computing applications (HPC).

“A new computing era has begun,” said Jensen Huang, founder and CEO of Nvidia. “Companies worldwide are transitioning from general-purpose to accelerated computing and generative AI.”

Nvidia’s revenue in the second quarter of fiscal 2024 reached $13.51 billion, marking a 101% rise from the previous year and an 88% jump from the previous quarter. Gaming revenue grew by 22% year-over-year, driven by demand for the GeForce RTX 40-series GPUs after inventory stabilization and the launch of multiple new offerings, including GeForce RTX 4060 and GeForce RTX 4070 class cards.

But sales of datacenter GPUs in Q2 FY2024 was Nvidia’s major triumph. It hit $10.323 billion, growing 171% year-over-year, and exceeded the datacenter revenue of AMD and Intel combined. Nvidia’s datacenter revenue saw significant growth driven by demand from cloud service providers. Nvidia’s HGX platforms based on the Ampere and Hopper GPU architectures were particularly sought after, especially for the development of large language models and generative AI. Additionally, the expansion of InfiniBand infrastructure, which supports the HGX platform, and the strong performance of the Hopper-based compute GPUs for HPC, further boosted the revenue.

“During the quarter, major cloud service providers announced massive Nvidia H100 AI infrastructures,” said Huang. “Leading enterprise IT system and software providers announced partnerships to bring Nvidia AI to every industry. The race is on to adopt generative AI.”

Other Nvidia businesses also performed very well. Professional visualization (ProViz) revenue declined 24% year-over-year but rose 28% quarter-over-quarter, influenced by enterprise workstation demand and new Nvidia RTX products. Automotive revenue increased 15% annually, boosted by autonomous platform sales, but dropped 15% quarterly due to reduced auto demand, notably in China.

Over the past few months we have heard rumors that Nvidia’s compute GPUs are sold out for quarters to come. Given the ongoing generative AI craze and demand for appropriate hardware, we’re not surprised, but since the sources of the information were unofficial, we took the data with a grain of salt.

But Nvidia seems to be extremely optimistic about its future. The company expects its revenue in Q3 FY2024 to be $16 billion ± 2% and gross margins to be between 71.5% to 72.5%.

The latest Windows 11 update is causing blue screens of death with a stop code of “unsupported processor” on some MSI motherboard-based PC systems. Microsoft has acknowledged the issue, noted the Verge, and stopped pushing KB5029351 updates to systems which would be adversely affected. MSI has yet to respond.

We have a pretty good idea about why some MSI motherboards are affected by this Microsoft OS update thanks to the experience of Tom Warren of The Verge and various redditors who have posted about their issues.

The “unsupported processor” BSOD only seems to appear on systems with MSI boards that have applied the latest BIOS updates. These BIOS files have been released for MSI Z690 and Z790 motherboards, in preparation for the arrival of Intel’s upcoming 14th Gen Core ‘Raptor Lake-S Refresh’ processors. They explicitly support “next-gen CPUs,” and appear to have caught Microsoft newest OS off guard.

Microsoft’s Windows 11 notoriously excludes what should be capable processors (like first gen Ryzen CPUs) from its compatibility list. Users of such systems have to fiddle with bypass techniques to get Microsoft’s latest OS to play nicely on their otherwise competent machines. It could well be the case that MSI’s BIOS tweak extending CPU support has triggered something in Microsoft’s CPU exclusion code.

“We are presently investigating to determine if this is an issue caused by Microsoft,” reads an update on the Windows Help Center. “We will provide an update when more information is available.”

So, what should MSI Z690 and Z790 motherboard users do now? If you haven’t already installed the Windows KB5029351 update, then put it off. If it is already installed and you get this BSOD, reports suggest that it is possible to recover Windows and rollback the patch. Coming at the problem from a different angle, you could avoid or roll-back the MSI BIOS update.

PC users with other motherboard brands might be wise to wait and see how MSI users get over this issue before seeking out similar 14th Gen Core CPU BIOS updates.

Several months back, Sony teased a dedicated remote-play device for the PlayStation 5. Now it’s got a name and a price. The PlayStation Portal will cost $200 when it lands later this year,.

Aesthetics-wise, it looks like a tablet wedged between two halves of a DualSense controller. The eight-inch LCD screen can stream games at up to 1080p visuals at 60 fps. The device also includes DualSense features, such as haptic feedback. It can stream games from your PS5 console, so when someone else is using the TV or you’re in another room (or even traveling), you can still play remotely via WiFi.

Sony

But it’s shaping up to be a surprisingly limited device if you’re outside of WiFi networks. PlayStation Portal doesn’t run any apps locally, with everything pulled from your PS5. Handhelds like the Razer Edge can are able to run Android apps locally, while some third-party devices, think the ASUS ROG Ally or a Steam Deck, can remote-play your PS5, too.

The biggest omission could be cloud game streaming, something available to PS Plus Premium subscribers with a PS5. Sony says cloud game streaming isn’t supported on the handheld.

PlayStation has confirmed an official launch price for the new PlayStation Portal remote player handheld, which was announced as being in development back in April. Users can expect a launch price of $199.99 (USD) for the new PlayStation Portal remote player when it’s released later this year.

The PlayStation Portal is a portable device featuring an 8-inch LCD screen with 1080p resolution and a refresh rate of 60 fps. It has haptic feedback and adaptive triggers, similar to the DualSense wireless controller, and is intended to work in tandem with the PS5 console over Wi-Fi.

The idea behind this handheld is to serve as an extension of the console. Any compatible games on the PS5 can be played on the PlayStation Portal remote player. Games that use the DualSense controller should be compatible but games that require additional hardware might not work. Users can also connect external audio peripherals using its 3.5mm audio jack.

Anything related to PS VR2 will not be compatible, as users must use the headset and VR controllers to interface. It’s also worth noting that games must be installed locally on the PS5. Anything hosted through PlayStation Plus Premium’s cloud streaming cannot be played on the PlayStation Portal remote player.

Because the PlayStation Portal remote player works in tandem with the PS5, it’s not in direct competition with other handhelds such as the Steam Deck or Asus ROG Ally. This also lends to its lower price threshold of $199. Though it’s possible this price might change in the future, it’s nice to have an official say so from Sony on the matter to set expectations.

You can read more about the PlayStation Portal remote player as well as new products, including the Pulse Elite wireless headset and Pulse Explore wireless earbuds, in the official announcement shared to the PlayStation blog.

One of the best CPUs for gaming has dropped to just $384, thanks to a drop in price on the AMD Ryzen 7 7800X3D CPU at B&H Photo. With 96MB of L3 cache, this CPU is great for gaming and also performs exceptionally well in productivity tasks.

One of the cheapest ways to upgrade to a bigger SSD in an older machine is to pick up the Team Group MP33 1TB SSD for just $35. It’s certainly not the fastest drive but with read/write speeds of 1800/1500MBps, but it’s more than adequate for most games and applications. 

Grab $50 off this impressive gaming keyboard, and take a look at the SteelSeries Apex Pro TKL wireless keeb for the reduced price of $199. It’s a pretty chunky price reduction for this keyboard and for the money you’re getting a compact TKL gaming keyboard that features SteelSeries’s OmniPoint 2.0 optical switches with per-key adjustable actuation and dual-action actuation, plus an OLED smart display configurable through the SteelSeries software.
