Razer revives its eGPU line with a Thunderbolt 5 dock

engadget.com Unknown 2025-07-24 11:15:26

Razer is back with a new addition to its Core line of external graphics enclosures. The Razer Core X V2 external graphics enclosure can house recent GPUs from brands including NVIDIA GeForce and AMD Radeon. It uses a single Thunderbolt 5 cable to the host device; in its press materials, Razer claims this tech delivers up to twice the bandwidth of Thunderbolt 4. This is true, but Thunderbolt 5 still isn't on the level of a modern desktop GPU connection, being roughly equivalent to 8 lanes of PCIe

NVIDIA is warning users to activate System Level Error-Correcting Code mitigation to protect against Rowhammer attacks on graphical processors with GDDR6 memory. The company is reinforcing the recommendation as new research demonstrates a Rowhammer attack against an NVIDIA A6000 GPU (graphical processing unit). Rowhammer is a hardware fault that can be triggered through software processes and stems from memory cells being too close to each other. The attack was demonstrated on DRAM cells but i

Tyr, a new Rust DRM driver targeting CSF-based ARM Mali GPUs

news.ycombinator.com Introducing Tyr 2025-08-07 15:07:13

The last year has seen substantial progress on the DRM infrastructure required to write GPU drivers in Rust. While a great part of it was fueled by the development of Nova (the new driver for GSP-based NVIDIA GPUs), and by AGX (the driver for the GPUs on Apple's M-series chip that preceded Nova), a few components were being worked on to cater to a then undisclosed driver that was being prototyped behind the scenes. A driver that we now introduce to the community at large in a very early stage.

AMD's strength historically lies at the budget end of the spectrum, where the majority of gamers are playing at 1080p, and spending $1,000 or less for their entire system.

Compiling LLMs into a MegaKernel: A path to low-latency inference

news.ycombinator.com Zhihao Jia 2025-09-03 10:20:54

One of the most effective ways to reduce latency in LLM inference is to fuse all computation and communication into a single megakernel — also known as a persistent kernel. In this design, the system launches just one GPU kernel to execute the entire model — from layer-by-layer computation to inter-GPU communication — without interruption. This approach offers several key performance advantages: Eliminates kernel launch overhead, even in multi-GPU settings, by avoiding repeated kernel invocatio

Zen 2’s launch was a defining moment for AMD. For the first time in many, many years, AMD’s single thread performance could go head to head with Intel’s best. Zen 2 also started a trend where AMD brought up to 16 cores to desktop CPUs, giving consumers very strong multithreaded performance without having to buy HEDT platforms. But Zen 2 was also flexible and did a very good job of scaling down to lower power targets. That was especially true when Zen 2 cores were implemented in more power effic
