According to Bloomberg's latest investigation, Huawei and Semiconductor Manufacturing International Corporation (SMIC) have submitted patents on the self-aligned quadruple patterning (SAQP) pattern etching technique to enable SMIC to achieve 5 nm semiconductor production. The two Chinese giants have been working with the Deep Ultra Violet (DUV) machinery to develop a pattern etching technique allowing SMIC to produce a node compliant with the US exporting rules while maintaining the density improvements from the previously announced 7 nm node. In the 7 nm process, SMIC most likely used self-aligned dual patterning (SADP) with DUV tools, but for the increased density of the 5 nm node, a doubling to SAQP is required. In semiconductor manufacturing, lithography tools take multiple turns to etch the design of the silicon wafer.

Especially with smaller nodes getting ever-increasing density requirements, it is becoming challenging to etch sub-10 nm designs using DUV tools. That is where Extreme Ultra Violet (EUV) tools from ASML come into play. With EUV, the wavelengths of the lithography printers are 14 times smaller than DUV, at only 13.5 nm, compared to 193 nm of ArF immersion DUV systems. This means that without EUV, SMIC has to look into alternatives like SAQP to increase the density of its nodes and, as a result, include more complications and possibly lower yields. As an example, Intel tried to use SAQP in its first 10 nm nodes to reduce reliance on EUV, which resulted in a series of delays and complications, eventually pushing Intel into EUV. While Huawei and SMIC may develop a more efficient solution for SAQP, the use of EUV is imminent as the regular DUV can not keep up with the increasing density of semiconductor nodes. Given that ASML can't ship its EUV machinery to China, Huawei is supposedly developing its own EUV machines, but will likely take a few more years to show.

ASUS finalized its adoption of the Intel Next Unit of Computing (NUC) product lines at a special autumn 2023 handover event. A post-ceremony statement outlined the company's vision going forward: "ASUS kicked-off its NUC business and started to take orders for NUC 10th to 13th generation systems on September 1. The new business is generating a wide variety of exciting opportunities for the company and the transition has progressed smoothly for NUC customers. The vision of the newly established ASUS NUC BU is to provide the most impactive edge computing with comprehensive commercial and AIoT solutions that can sustain the industry and businesses." Just over a week ago, TechPowerUp was granted access to next generation NUC devices at CES 2024—including ROG NUC, as well as NUC 14 Pro and NUC 14 Pro+ models. Many folks in attendance noticed a complete absence of NUC Extreme products at the ASUS Las Vegas showroom.

Online publication, Fudzilla, has investigated this matter—Fuad Abazovic (Editor-in-Chief) managed to chase down an ASUS spokesperson. It seems that the Taiwanese manufacturer is integrating some if its best known branding into the NUC ecosystem, and Team Blue nomenclature is on the chopping block: "the company won't have an update to the NUC Extreme 7.5 liter device. The Raptor Canyon remains the last NUC of its kind, as ASUS has ROG Strix systems in the same ballpark. Fudzilla already covered the announcement of the NUC and NUC pro, and the ROG NUC. We were assured that the 2.5L ROG NUC will remain the fastest gaming-oriented device and that, at this plan, the company doesn't plan to develop the successor of NUC Extreme 7.5 liter. ASUS has announced ROG Strix G16CHR, its 7.5-liter desktop that comes with an air and water cooler and hosts up to Intel Core i7-14700KF Processor 3.4 GHz (33M Cache, up to 5.5 GHz, 20 cores), NVIDIA GeForce RTX 4080 16 GB GDDR6X 3x DP, 2x HDMI, and up to 64 GB RAM in 4x DDR5 U-DIMM slots."

Over the past few months there have been reports of issues with SanDisk portable SSDs and Western Digital released a firmware update in May that was meant to prevent the drives from "unexpectedly disconnect from a computer". However, it appears that this firmware update didn't solve the problem and Western Digital is now being taken to court over drives not just having disconnect issues, but also randomly failing. The court case is expected to become a class action suit, as the plaintiff claims that the issue of failing drives affect tens, if not hundreds of thousands of people in the USA.

The models included in the complaint includes the SanDisk Extreme Pro, Extreme Portable, Extreme Pro Portable and WD My Passport SSD. A further firmware update was released in July, which is said to have made the issues even worse, with data being lost on drives or being inaccessible to drive owners. In some cases the drives go into read only mode, but sometimes this means that the drives become inaccessible to the OS, which in turn also means dataloss to the user. Time will tell how this plays out, but it's not looking great for Western Digital, but it wouldn't be the first time a storage device maker has been taken to court over failing products.

Galax has today announced a new flagship SSD for the Chinese market—ITHome noticed the Hall of Fame (HOF) Extreme 50S PCIe 5.0 SSD's reveal on Weibo. A very similar looking and named model was released a few months ago, but the new contender has added an "S" to its designation, so we expect it to offer a performance upgrade over its non-S sibling (a top performer for its time). Galax's own lab tests propose that the successor is capable of delivering read and write speeds up to 12.4 GB/s and 11.8 GB/s (respectively), a nice bump up from the previous gen model's 10.0 & 9.5 GB/s. ITHome's report suggests that these new storage drives are capable of reaching 1500K IOPS.

The HOF Extreme 50S and HOF Extreme 50 (non-S) series share the same Phison controller - PS5026-E26 - according to news sources. There are no differences in terms of NAND and cache configurations, but the newer models are likely faster thanks to refined ECC algorithm technology and fifth-generation LDPC error correction capabilities. No pricing and launch date(s) were available at the time of writing—ITHome understands that Galax will release a 2 TB model first, and a 4 TB will follow it.

Extreme Networks, Inc., today introduced a number of new solutions designed to challenge the status quo of networking. The AP3000 is the industry's smallest, most power-efficient Wi-Fi 6E access point (AP) and is designed to meet the needs of budget-conscious customers who want enterprise-grade performance in a small package. Extreme also extended its Universal Switch series with the introduction of the 7520 and 7720 switches, custom-built for enterprise core and aggregation use cases, and 8820 switches, high-density, deep buffer, switch routers designed for large enterprise networks. Extreme's Universal Platforms enable users to select their OS and change it as necessary, extending the life of the hardware and eliminating network upgrade costs.

"With more IoT and student devices connecting to the network each day and an ever-increasing need to invest in innovative software applications to boost curriculums and learning, Wi-Fi 6E will be a game-changer for the way we leverage our network to drive better experiences across campus. What makes the AP3000 so appealing is its small form factor, low power consumption and ability to perform in challenging conditions like auditoriums with high ceilings and small offices or classrooms in tight corners. Students and faculty connected to our new Wi-Fi 6E network will see a major difference in how quickly they can access online resources like videos, without any buffer time or interruptions to their school day," said Matthew Dumond, IT Director, Prospect Mountain School District.

The ASUS ROG Ally handheld games console emerged last month and it was revealed to pack some impressive "custom" AMD hardware - the two companies have boasted that the collaboration has resulted in two special SoCs - the Ryzen Z1 and Ryzen Z1 Extreme. Silicon enthusiasts were quick to point out that the Z1 series sported similar specifications to mobile/ultra-portable chipsets in AMD's 7040U family - in particular the Ryzen 7 7840U looks almost identical to its gaming equivalent (Ryzen Z1 Extreme). Andrew E. Freedman at Tom's Hardware was curious and motivated enough to request clarification (about this situation) from AMD. Team Red were happy to respond and acknowledged the apparent similarities between the gaming and laptop chipset ranges, but also stated that Z1 APUs have been tweaked by company engineers to a certain degree.

Matthew Hurwitz, a client PR manager at AMD, provided a response to the Tom's Hardware-issued query: "The Ryzen Z1 series are purpose-built with handheld gaming in mind. To accomplish this, AMD engineers had to validate entirely new power ranges and optimize the voltage curves specifically for this use case - this optimization and validation work should not be trivialized. So while the technology building blocks (like 'Zen 4' and RDNA 3) are similar between the 7040 and Z1 series, the resulting models have very distinct characteristics customized for their use cases. In addition, the AMD Ryzen AI engine is not available on AMD Ryzen Z1 series processors." Hurwitz also confirmed that AMD's XDNA AI engine is merely disabled (so not removed at hardware level) on the two Z1 APUs - this feature is only enabled on the range-topping Ryzen 7 7840U model and mid-range Ryzen 5 7640U. So yes, there are small differences but AMD and ASUS have probably saved some money on development costs by creating and adopting the "slightly adjusted" Z1 SoC series.

Update May 6th: Tom's Hardware has amended their article (as of May 5, 5:03 p.m. ET) - another source within AMD has informed them about the Z1 and Z1 Extreme APUs having configurable TDPs of 9 W to 30 W. The original story - and AMD's website - claimed a range of 15-30 W.

An intriguing entry has appeared on the Geekbench Browser site, the information was uploaded with a timestamp from this morning (11:07 am on April 20 to be specific) pointing to a mobile ASUS device that was tested in GeekBench 5. The archived info dump reveals that the subject matter of the benchmark was the ASUS ROG Ally handheld gaming console, which has received a lot of attention in recent weeks - with it being touted as a very serious alternative to Valve's Steam Deck, a handheld gaming PC that is quite popular with enthusiasts. The ROG Ally will need to offer a potent hardware package if it stands to compete directly with the Steam Deck, and the latest information confirms that this new contender is very promising in that department. Geekbench 5 awarded an impressive OpenCL score of 35498 to the RC71L variant of the ROG Ally, an RC71X-assigned model is known to exist but details of its exact nature have not been revealed. This particular ROG Alloy unit was running Windows 11 Home (64-bit) under the operating system's performance power plan.

The new entry on Geekbench Browser shows that the Ally is packing an AMD Ryzen Z1 Extreme APU, which appears to be a customized version of the Ryzen 7 7840U APU mobile platform chipset - previous rumors have indicated that the latter would be in the driving seat. Both Phoenix range SoCs share the basic 8 cores and 16 thread makeup, but the Z1 Extreme is capable of boosting up to 5.062 GHz from a base frequency of 3.30 GHz. AMD's Radeon 780M iGPU (RDNA 3) is expected to deal with the Ally's graphical aspect, but the benchmark info dump only provides scant details about the GPU (codenamed "gfx1103") - most notably the presence of six computer units, an 800 MHz max frequency, and access to 8.20 GB of video memory. Number crunching boffins have calculated that the Ally could field 768 FP32 cores, courtesy of the dual issue SIMD design inherent to RDNA 3.
