Custom Raspberry Pi 5 case rebuilds Pi 5 open loop into the hyper-compact case with the loop still intact — system stays below 43ºC at max load

(Image credit: Michael Klements on YouTube) Earlier today, YouTuber Michael Klements uploaded a detailed build log showcasing his custom, water-cooled Raspberry Pi 5 case, including an open loop and acrylic side panel, at a footprint competitive with the best retail Pi 5 cases. This was accomplished using lots of retail hardware, including an existing (overkill)… Read more

Intel’s latest Arrow Lake CPU firmware reportedly offers little to no performance gains — users test the microcode ahead of launch on the ASRock Z890 Taichi OCF

The 0x114 microcode for Intel’s Core Ultra 200S (Arrow Lake) processor lineup has surfaced online at Overclock.net. This patch is believed to address the significant performance gaps. However, forum users report negligible gains in performance. It is important to note that motherboard vendors have yet to officially release this microcode, which is apparent because it… Read more

Sony PlayStation 3 emulator RPCS3 now natively supports Arm64 architecture — including Raspberry Pi 5

This week, developers behind the PlayStation 3 emulator RPCS3 announced that RPCS3 had now achieved stable, native Arm64 architecture support for Windows, macOS, and Linux platforms— Arm64 architecture support so definitive that it even includes the Raspberry Pi 5, of all devices, utterly pushing the limits of emulation believed possible on the Raspberry Pi 5….

BadRAM attack breaches AMD secure VMs using a Raspberry Pi Pico, DDR socket, and a 9V battery

Researchers have described the BadRAM attack, which is claimed to facilitate the breaching of processor security “via rogue memory modules” (h/t The Register). Specifically, the research team has outlined a successful attack on AMD’s cutting-edge Secure Encrypted Virtualization (SEV) using a $5 Raspberry Pi Pico connected to a DDR socket and powered by a 9V… Read more

AMD shares 30×25 progress: New AI machines are 28.3 times faster than 2020 machines

Performance efficiency is key to rapid performance increase of AI and HPC processors, so AMD and other companies are fighting for it fiercely with every new product generation. Back in 2021, the company set itself a goal of 2025 to increase the energy efficiency of its EPYC processors and Instinct accelerators by 30 times compared… Read more

Marvell develops custom HBM solution that offers higher performance in a smaller physical space

(Image credit: Marvell) Marvell has announced custom high-bandwidth memory (CHBM) solution for its custom XPUs designed for AI applications at its Analyst Day 2024. Developed in partnership with leading memory makers, CHBM promises to optimize performance, power, memory capacity, die size, and cost for specific XPU designs. CHBM will be compatible with Marvell’s custom XPUs… Read more

TSMC founder says Intel has neither a strategy nor a CEO

It’s still arguably too early to confidently state how successful Intel’s 18A process technology (1.8nm-class) will be. But in about a year, we should know if Pat Gelsinger’s five nodes in four years plan was a success. That said, Intel’s failure to offer a competitive AI processor is evident even today, which gives Morris Chang,… Read more

30-year-old Pentium FDIV bug tracked down in the silicon — Ken Shirriff takes the microscope to Intel’s first-ever recall

Noted hardware historian and reverse-engineer Ken Shirriff recently found the exact transistors in the original Intel Pentium which caused the “FDIV bug”, leading to a $475 million recall in 1994. As seen on his Mastodon thread, Shirriff took a microscopic dive into the PLA which holds a faulty division table, tracking down the root cause… Read more

Cyberpunk 2077 update 2.2 claims to improve Arrow Lake performance by up to 33%, theoretically matching the Ryzen 7 7800X3D

The new update brings with it an onslaught of gameplay changes and updates, including performance enhancements. Update 2.2 promotes a whopping 33% performance improvement on Core Ultra 200S… Read more

Nvidia reveals detailed ray tracing differences, promotes DLSS 3 for Indiana Jones and the Great Circle

Last week, the (relatively) sky-high system requirements of Indiana Jones and the Great Circle proved to be one of the most talked-about stories in PC hardware that week. This week, though, the game is out, and Nvidia is already promoting it. The extent of its “Full Ray Tracing” graphics feature additions adds some Path Tracing… Read more

Researchers develop memory that functions with temperatures over 1,100°F — nonvolatile electrochemical memory works even on the hottest planet in our solar system

Traditional DDR memory operates within a certain temperature window—often around 100 degrees Celsius or less—and going beyond that window will result in potential data loss and thermal throttling. Researchers at the University of Michigan have developed a new memory architecture that quite literally behaves the opposite of DDR memory, featuring an operating window of at… Read more

Lam Research unveils Dextro, maintenance robot for fabs

On Tuesday, Lam Research introduced its Dextro collaborative robot (cobot), which promises to enable accurate and repeatable maintenance of fab tools. Typical wafer fabrication facilities house hundreds of tools that require complex maintenance regularly. Accuracy in tool maintenance is essential, as the precise assembly of subsystems directly impacts yields. However, human beings are not as… Read more
