We spotted via IT Home a fresh PC case just released by GALAX under the name "Metal Master Dark Guard", a new case that works with both ATX and microATX (back connectors supported) motherboards. The case keeps the look of the Metal Master series, with clean lines and a nice beveled design. It also has a big tempered glass side panel that gives you a clear view of internal components. The case internal design shows special attention to cooling, as GALAX mentions that they put it through multiple airflow tests. It can fit up to eight 120 or 140 mm fans, and one 240/260/280 mm radiator which makes it great for high-end gaming PCs. The design has a smart air duct system to keep things cool, and there's plenty of room inside to make cable management easy. One cool thing about the design is that the USB 3.0, and Type-C connectors are placed at the front-bottom. This helps keep the overall look clean by hiding cables away from the user's eyes while keeping the airflow clean.

The case can fit the latest hardware components, including the new RTX 50 series graphics cards or any graphic card up to 400 mm long, and standard power supplies. GALAX has priced the Metal Master Dark Guard at 249 yuan about $35, at least that's the price on Asian markets. If it reaches Western markets around $50 it can be considered a viable option for those on a tight budget.

Shrinking components was (and still is) the main way to boost the speed of all electronic devices; however, as devices get tinier, making them becomes trickier. A group of scientists from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University has discovered another method to enhance performance: putting a special metal layer known as a metamaterial on top of a silicon base to make electrons move faster. This approach shows promise, but the tricky part is managing the metamaterial's structure so it can adapt to real-world needs.

To address this, the team looked into vanadium dioxide (VO₂). When heated, VO₂ changes from non-conductive to metallic, allowing it to carry electric charge like small adjustable electrodes. The researchers used this effect to create 'living' microelectrodes, which made silicon photodetectors better at spotting terahertz light. "We made a terahertz photodetector with VO₂ as a metamaterial. Using a precise method, we created a high-quality VO₂ layer on silicon. By controlling the temperature, we adjusted the size of the metallic regions—much larger than previously possible—which affected how the silicon detected terahertz light," says lead author Ai I. Osaka.

"Our solution enables computers to retrieve data significantly faster than before, as the cache can manage far more processing elements (PEs) than most existing systems. This makes it possible to meet the demands of tomorrow's powerful computers," says Per Stenström, Professor at the Department of Computer Science and Engineering at Chalmers University of Technology and the University of Gothenburg.

Intel's Platform Engineering and Client Segments groups are actively looking into ways of reducing computer e-waste, and (in parallel) enhance product repairability. The company's newly proposed "Modular PC Design" is set to take a "sustainable approach" across three key modularity levels: factory, field and user. Team Blue's blog post goes into great detail about revised laptop and mini-PC designs—with the "right-to-repair" movement serving as a major influence. Many "consumer activists and environmental groups" have advocated for improvements in personal computer design—Intel appears to be listening, but a firm release timeline has not been set.

Intel's proposed new standards will revolve around repairability and upgradability—as explained in their blog: "the right-to-repair emphasizes the importance of being able to fix and upgrade PCs on one's own. Improving repairability requires fundamental changes starting from the design methodology." Team Blue's Modular PC program—for laptops—breaks away from the tradition of utilizing an "all-in-one motherboard." A reference diagram shows off three internal modules: a motherboard package and two "universal" left and right I/O units. These separate boards can be: "utilized across various platforms or market segments leads to cost savings by streamlining the duration of the design cycle and minimizing the engineering investment required. The I/O boards for Premium Modular designs are engineered to be common between the fan-less Thin & Light system, which operates within a 10 W power envelope, and the premium fanned designs, which function within a 20 W (single fan) and 30 W (dual fan, Wi-Fi only SKU) power envelope." Framework recently celebrated its fifth year of operation—its modular laptop designs have seemingly "inspired" a few copycats.

During its Q2 2024 earnings call, NVIDIA confirmed that its upcoming Blackwell-based products are facing low-yield challenges. However, the company announced that it has implemented design changes to improve the production yields of its B100 and B200 processors. Despite these setbacks, NVIDIA remains optimistic about its production timeline. The tech giant plans to commence the production ramp of Blackwell GPUs in Q4 2024, with expected shipments worth several billion dollars by the end of the year. In an official statement, NVIDIA explained, "We executed a change to the Blackwell GPU mask to improve production yield." The company also reaffirmed that it had successfully sampled Blackwell GPUs with customers in the second quarter.

However, NVIDIA acknowledged that meeting demand required producing "low-yielding Blackwell material," which impacted its gross margins. During an earnings call, NVIDIA's CEO Jensen Huang assured investors that the supply of B100 and B200 GPUs will be there. He expressed confidence in the company's ability to mass-produce these chips starting in the fourth quarter. The Blackwell B100 and B200 GPUs use TSMC's CoWoS-L packaging technology and a complex design, which prompted rumors about the company facing yield issues with its designs. Reports suggest that initial challenges arose from mismatched thermal expansion coefficients among various components, leading to warping and system failures. However, now the company claims that the fix that solved these problems was a new GPU photomask, which bumped yields back to normal levels.

Newegg's trade-in program allows customers to trade in their existing aged CPUs for credit toward a new CPU.

Researchers from the University of California, San Diego, have unveiled a significant security vulnerability affecting Intel Raptor Lake and Alder Lake processors. The newly discovered flaw, dubbed "Indirector," exposes weaknesses in the Indirect Branch Predictor (IBP) and Branch Target Buffer (BTB), potentially allowing attackers to execute precise Branch Target Injection (BTI) attacks. The published study provides a detailed look into the intricate structures of the IBP and BTB within recent Intel processors, showcasing Spectre-style attach. For the first time, researchers have mapped out the size, structure, and precise functions governing index and tag hashing in these critical components. Particularly concerning is the discovery of previously unknown gaps in Intel's hardware defenses, including IBPB, IBRS, and STIBP. These findings suggest that even the latest security measures may be insufficient to protect against sophisticated attacks.

The research team developed a tool called "iBranch Locator," which can efficiently identify and manipulate specific branches within the IBP. This tool enables highly precise BTI attacks, potentially compromising security across various scenarios, including cross-process and cross-privilege environments. One of the most alarming implications of this vulnerability is its ability to bypass Address Space Layout Randomization (ASLR), a crucial security feature in modern operating systems. By exploiting the IBP and BTB, attackers could potentially break ASLR protections, exposing systems to a wide range of security threats. Experts recommend several mitigation strategies, including more aggressive use of Intel's IBPB (Indirect Branch Prediction Barrier) feature. However, the performance impact of this solution—up to 50% in some cases—makes it impractical for frequent domain transitions, such as those in browsers and sandboxes. In a statement for Tom's Hardware, Intel noted the following: "Intel reviewed the report submitted by academic researchers and determined previous mitigation guidance provided for issues such as IBRS, eIBRS and BHI are effective against this new research and no new mitigations or guidance is required."

HP has envisioned a new approach to MicroLED monitors that could revolutionize how we design and buikd displays. Dubbed "Composable MicroLED Monitors," this concept proposes a modular system where users can assemble their desired monitor configuration from multiple components. At the core of this concept lies a base unit that serves as the foundation, housing the necessary connections and a stand. Users can then attach flat or curved extension modules to the base, allowing various display sizes and formats. These modules resemble puzzle pieces, seamlessly integrating with the base unit through magnetic holders that ensure precise alignment. The true beauty of this concept lies in its scalability and customization options. By combining multiple base units and extension modules, users can create displays of virtually any size or shape tailored to their specific needs.

Whether it's a compact, single-screen setup or an immersive, curved multi-monitor array, the possibilities are endless. HP's illustrations showcase the potential of this concept, with a proposed base unit size of 12" x 12" and extension modules measuring 12" x 6". With integrated switches or software controls, users can even specify how the operating system treats the connected display tiles - as a unified, large display or as separate, independent screens. While this concept's modular nature promises infinite flexibility, it also presents a challenge: the inevitable gaps between modules. HP's research paper delves into potential solutions to minimize these gaps, ensuring a seamless visual experience for users. Whether HP's "Composable MicroLED Monitors" concept will transition from a study to a tangible product remains to be seen. However, one thing is sure: this pioneering approach could open up a world of possibilities for display technology, enabling users to create truly personalized and tailored visual experiences.

The Taiwanese Ministry of Economic Affairs (MOEA) managed to herd government representatives and leading Information and Communication Technology (ICT) industry figures together for an important meeting, according to DigiTimes Asia. The report suggests that the main topic of discussion focused on an anticipated growth of Taiwan's ICT industry—current market trends were analyzed, revealing that the nation absolutely dominates in the AI server segment. The MOEA has (allegedly) determined that Taiwan has shipped 90% of global AI server equipment—DigiTimes claims (based on insider info) that: "American brand vendors are expected to source their AI servers from Taiwanese partners." North American customers could be (presently) 100% reliant on supplies of Taiwanese-produced equipment—a scenario that potentially complicates ongoing international tensions.

The report posits that involved parties have formed plans to seize opportunities within an evergrowing global demand for AI hardware—a 90% market dominance is clearly not enough for some very ambitious industry bosses—although manufacturers will need to jump over several (rising) cost hurdles. Key components for AI servers are reported to be much higher than vanilla server parts—DigiTimes believes that AI processor/accelerator chips are priced close to ten times higher than general purpose server CPUs. Similar price hikes have reportedly affected AI adjacent component supply chains—notably cooling, power supplies and passive parts. Taiwanese manufacturers have spread operations around the world, but industry watchdogs (largely) believe that the best stuff gets produced on home ground—global expansions are underway, perhaps inching closer to better balanced supply conditions.

In developing the OPX1000, a controller fit for the ever-growing quantum processors counting 1,000 qubits and beyond, we had to think deeply about every detail that impairs scalability. Our recently unveiled OPX1000 module for microwave generation (MW-FEM) generates pulses up to 10.5 GHz directly, without analog oscillators or mixers. The choice of technology to reach microwave frequencies is not trivial. We choose cutting-edge direct digital synthesis (DDS) for very specific reasons, and we believe it will enable scalability and performance to an even greater degree. In this blog, we dive deeper into the considerations for going this route and existing alternatives. So stick around, whether you like mixers or hate them, this will be an interesting ride.

Summary of Technologies for Microwave Operation
The control signals for qubit drive and readout often fall in the microwave range, which is outside the range of baseband controllers. Many qubit labs have solved the issue with solutions based on mixing, including single sideband mixers, IQ-mixers, or more complicated schemes such as double super-heterodyne (DSH) conversion. Mixer-based solutions make use of analog local oscillators (LOs) that are multiplied by the signal of a controller or an AWG. IQ-mixers naturally suffer from two main spurs (affectionate name for unwanted signals), the LO leakage and the mixer image, which require non-trivial calibration to be removed. Other schemes, such as double super-heterodyne, offer a zero-calibration solution but use many more components. Additionally, mixing schemes require having an LO source per mixer if different drive frequencies are used. Having a low phase source per mixer is very expensive, and in order to cut prices, will probably include a phase-lock loops (PLL), leading to phase differences between channels, which is detrimental for multi-qubit systems. In other words, while mixers can be useful, we need to be aware of the pros and cons involved.
