Update 29-06-2025 4:21 PT:Clarified the below text that not all of the 100 reports are indicative of chip failures. Rather, some could be due to boot issues. Updated article: TheRyzen 7 9800X3D, regarded as one of thebest CPUs, has captured the attention of gamers seeking to upgrade their gaming rigs. However, AMD’s3D V-Cachechip has also sparked another discussion, as user feedback regarding alleged premature failures onReddit(courtesy of natty_overlord) has grown to over 100 cases....

A startup company in Italy isdeveloping a much less expensive solutionfor underwater communication than is currently available. They’ve incorporatedRaspberry Piinto low-cost alternatives to two critical and costly parts of underwater acoustic communication: the modem and the transducer. The SubSeaPulse SRL venture is led by Filippo Campagnaro and Michele Zorzi, researchers from the University of Padova in Italy. The pair aims to makeunderwater communicationmore accessible. Currently, modems for transmitting and receiving sound signals underwater can cost more than $10,000....

A curiosity recently caught our eye—that curiosity is KolibriOS, a super-lightweight, ultra-fast OS designed for legacy PCs with its floppy drive-friendly install size of just 1.44 MB. PerHackaday’s coverage, which drew our attention to YouTuber Michael MJD’s extended video coverage of the operating system, KolibriOS started as a 32-bit fork of MenuetOS in 2004. Since then, KolibriOS has become widely multi-platform while maintaining a 32-bit focus and becoming lightweight enough to run on any PC with an i585-compatible CPU, 8MB of RAM, and a VESA-compatible video card....

One of the less-noticed tidbits from last week’sTSMC North American Technology Symposiumwas announcement that Tesla’s Dojo system-on-wafer processor for AI training is now in mass production and is on track to be deployed shortly. More details about the giant processor were revealed at the event. Tesla’sDojo system-on-wafer processor(or, as Tesla calls it, the Dojo Training Tile) relies on a 5-by-5 array of known good processor chips (which are reticle size, or close to that) that are placed on a carrier wafer and interconnected using TSMC’s integrated fan-out (InFO) technology for wafer-scale interconnections (InFO_SoW)....

Chinese memory makers are slowly but surely adopting the production of high-bandwidth memory (HBM) for AI and HPC processors. This week,Nikkeireported that a third China-based producer, Tongfu Microelectronics, began sampling its HBM products with select customers. Such action indicates that the ecosystem required to make this type of memory is developing. Interestingly, AMD is a major client and shareholder of Tongfu. Truth to be told, Tongfu Microelectronics is not exactly a DRAM maker....

Open-loop cooling provides some of the best results, particularly when you have the right water block to put on your graphics card. However, when you have to start putting in your own coolant, cutting the tubes, and filling a reservoir, it’s an expensive hassle and risky should your coolant leak onto your components. Lynk+, a German startup, has a solution. Why not build the ultimate water block into your graphics card and then sell AIO coolers that can attach to it?...

The SSD Pro5, announced at CES 2025, is designed to meet the storage demands of professionals working with large data files, such as raw images, video, and high-resolution audio....

President Donald Trump announced he will introduce new tariffs specifically aimed at semiconductors next week,Reutersreports. Trump noted that there would be ‘flexibility’ for some companies in the sector, which probably means that some companies will not have to pay tariffs at all, or pay less than others. “We wanted to uncomplicate it from a lot of other companies because we want to make our chips and semiconductors and other things in our country,” Trump told reporters aboard Air Force One....

We had the opportunity to interview TSMC’s Kevin Zhang, the deputy co-COO and SVP at TSMC, to discuss the latest trends in the semiconductor industry and how they impact TSMC’s strategy moving forward.Since its founding in the 1980s, TSMC’s business strategy has been to meticulously fulfill the needs of its customers, transforming itself in accordance with the ever-evolving semiconductor landscape. In the coming years, the needs of the company’s clients will become so diverse that it will offer different leading-edge production capabilities for segment-specific needs, marking a major milestone in its ‘Everyone’s Foundry’ ideology....

Ransomware gangs might have to scratch a few targets off their lists. The UK High Office and National CyberSecurityCentre (NCSC) announced proposals to ban ransom payments in an effort to “crack down on cyber criminals and safeguard the public.” According to theannouncement, the proposals would prohibit “public sector bodies and operators of critical national infrastructure, including the [National Health Service], local councils and schools,” from making ransomware-related payments. They would also require other businesses planning to pay a ransom to notify the UK government so it can “provide those businesses with advice and support” before the payment is made....

Two years ago, a bug report pointed out that the open-source Linux graphics library Mesa’s RADV (RadeonVideo) driver for AMDRDNAandGCNarchitecture GPUs had “significantly less” performance than the AMDGPU-PRO driver within the AMD FSR2 sample app. This issue has finally been fixed [h/tPhoronix]. ValveLinux driver team engineer Samuel Pitoiset fixedan issuethese architectures had with culling triangles and lines when all W positions were zero. Since culling relates to the clearing of assets from the cache to improve performance, it makes sense that key culling optimizations can net huge gains....

It seems like an ethernet connection will always be faster for many people than a wireless connection, and that’s a fair assumption. A wireless connection running on the same network as an ethernet connection will be slower as a wireless connection is subject to more interference than a direct-wired connection. If your wireless signal is faster than your ethernet, it may be a glitch, or a few different things may be happening to cause it....
