Without obtaining an export license from the U.S. Department of Commerce, Nvidia cannot supply its high-endH100and the latestH200GPUs to China-based entities. This license will hardly be granted, at least not for hundreds of such GPUs. However, these GPUs are seemingly available in China, with one alleged businessman bragging that he had smuggled in over two dozen H200-based Supermicro servers with hundreds of H200 GPUs inside. The unidentified businessman allegedly obtained as many as 25 Supermicro servers, each with eight Nvidia H200 GPUs, amounting to 200 Hopper GPUs....

Chinese tech giants have collectively spent over $16 billion on Nvidia’s H20 data center GPUs for AI so far this year, according toReuters, which cites a report fromThe Information. Chinese companies increased their spending on Nvidia GPUs despite the expected ‘DeepSeek impact’ andunused AI infrastructure in China. This likely happened as a response to theAI diffusion rule proposed by the previous U.S. governmentthat bans Chinese entities from buying American AI GPUs starting in May....

If your PC suddenly stops booting, a critical part like the PSU or motherboard is probably dead. Once youidentify and fix/replace the faulty component, your PC should start working again. I’ll take you through astep-by-step troubleshooting processto help you do this. You should start by confirming that your computer is actually receiving power. Verify Power Supply Status When you press your PC’s power button, there should be some signs of life (fans starting, LEDs, etc....

CPU fan is different from the casing fans in the sense that the CPU fan has a failsafe connection. That is to say, if it is not connected to the system, the system will not even start to protect the integrity of the CPU. So, when your PC shows the “CPU Fan Not Detected” error, it usually means that the fan connection is not made properly. But sometimes, the system may not be able to detect the fan due to hardware issues or software bugs....

TrashBench, an overclocking and BIOS tuning enthusiast, has pushed the old favorite NvidiaGeForce GTX 1060to 2,202 MHz using a DIY cooler. TheRedditorand TechTuber stuck to the aging GeForce’s stock BIOS and stock voltage, but the home-made copper pipe cooling can only be reasonably described as ‘something else.’ Aesthetics aside, the cooler propelled this card to a stunning five-fold victory in the official 3DMark Fire Strike chart (for systems packing aCore i5-12600KF)....

We see lots of pre-built and configurable gaming desktops atCES, and most of them these days sport a plethora of glass side panels, aggressive angles, and RGB lighting. CyberPower’s Amethyst 360S Series takes that look and slaps on wood slats in your choice of light or dark colors. It’s a bold and unique look that certainly won’t be for everyone, but it certainly stood out in the blur of meetings and cascade of new products as I trudged around Las Vegas....

DeepCool has unveiled a new portable Mini-ITX chassis with more mesh paneling than a typical ATX chassis. Dubbed theCH160, theMini-ITXcase sportsmesh panelingon the top, front, rear, bottom, and right side panel to maximize airflow. The only part of the case that is not mesh is the left side panel, which is tempered glass. The CH160 follows a new trend in high-performance airflow-optimized cases where right-side mounted mesh panels are being installed in place of solid side panels, to boost airflow potential as much as possible....

Ever wanted to see an original Xbox runHalo 2at HD resolutions — or at least a non-distorted widescreen image at 480p? Hardware and game modder Ryan Miceli, aka grimdoomer on GitHub, has made the dream ofHalo 2in HD on Xbox a reality, though you’ll need to make some modifications. Miceli haslisted the project on GitHuband described it in depthon his blog. This doesn’t run at 720p on the original Xbox as you may have bought it years ago....

Nvidia has reportedly broken another AI world record, breaking the 1,000 tokens per second (TPS) barrierper userwith Meta’s Llama 4 Maverick large language model, according toArtificial Analysisin a post on LinkedIn. This breakthrough was achieved with Nvidia’s latest DGXB200node, which features eight Blackwell GPUs. Nvidia outperformed the previous record holder, SambaNova, by 31%, achieving 1,038 TPS/user compared to AI chipmaker SambaNova’s prior record of 792 TPS/user. According to Artificial Analysis’s benchmark report, Nvidia and SambaNova are well ahead of everyone in this performance metric....

A higher polling rate does matter in a mouse. However, a higher polling rate on a keyboard is debatable on whether it improves your gaming performance. Since a mouse constantly sends data about its position to the Operating System, it benefits from the higher polling rate. The keyboard, on the other hand, does not constantly send data. It only records data once you press on it. Therefore, unless you press a button faster than the keyboard’s polling rate, the keyboard will always detect a button press....

Afaster RAM is usually bettercompared to one with a lower speed. However, there are situationswhere installing a slower RAM makes more sense. It all depends on user requirements. On an intensive workload system or gaming PCs, high-frequency RAM is recommended. However,for casual usage, you don’t really need it. Another thing to keep in mind isits latency. If you want to improve system performance, consider getting a lower latency RAM. Now, let’s look at some aspects whereRAM speedmatters and where it does not....

It’s a known fact that an ethernet connection is faster and more stable than a wireless one. However, an ethernet connection is also more prone to technical and hardware-related issues than your Wifi. And usually, these issues emerge from the ethernet port of your motherboard. Unless the only fix for you is to buy a USB ethernet adapter, this guide shall take you through all the alternative methods you can seek to fix your port issues from the comfort of your home....

Researchers at theOak Ridge National Laboratory (ORNL)recently successfully developed a transistor fashioned out of Gallium Nitride (GaN) that can withstand the heat and radiation near the core of a nuclear reactor. Scientists found that the GaN transistor can survive temperatures up to 125 degrees Celcius (257F), the limits of the reactor’s safety threshold, and they predict it can last for five years in the extreme conditions. Traditional silicon-based transistors could not withstand the intense nuclear environments, thus requiring them to be placed behind shielding....
