AMD EPYC 4004 Benchmarks: Outperforming Intel Xeon E-2400 With Performance, Efficiency & Value
78 Minutes Ago - Processors - Add A Comment

Over the past several years we have seen AMD Ryzen processors being used for low-cost servers, budget web hosting platforms, game servers, and more. Since the Ryzen 5000 series we have seen the likes of ASRock Rack and Supermicro putting out interesting budget-friendly Ryzen servers and that has ramped up even more with AMD Ryzen 7000 series server performance being stellar thanks to AVX-512 and other improvements making it more practical for such workloads. AMD has now solidified its positioning for entry-level servers with the introduction of the EPYC 4004 series processors. The EPYC 4004 series is derived from the Ryzen 7000 series offerings to facilitate cost conscious server options and putting the Intel Xeon E-2400 series in the crosshairs. In this review is a look at the EPYC 4004 series along with benchmarks of nearly the entire EPYC 4004 product stack compared to Intel's current top-end Xeon E-2400 series processor, the Intel Xeon E-2488 Raptor Lake.

Farewell Intel Xeon Phi: Support Removed In The GCC 15 Compiler
Farewell Intel Xeon Phi: Support Removed In The GCC 15 Compiler
20 May 09:40 AM EDT - Intel - GCC 15 Drops Xeon Phi - 4 Comments

Last week I wrote about Intel aiming to remove Xeon Phi support in GCC 15 with the products being end-of-life and deprecated in GCC 14. While some openly wondered whether the open-source community would allow it given the Xeon Phi accelerators were available to buy just a few years ago and at some very low prices going back years so some potentially finding use still out of them especially during this AI boom (and still readily available to buy used for around ~$50 USD), today the Intel Xeon Phi support was indeed removed.

It was just earlier this month that AMD Linux kernel graphics driver patches appeared for introducing a new ISP hardware block for Image Signal Processing with new AMD APUs. Already the AMDGPU ISP firmware has appeared in linux-firmware.git indicating that this "ISP" block may be coming in hardware quite soon if not already quietly found within some products.

While EROFS is seeing Zstd support and Bcachefs is seeing performance optimizations with the in-development Linux 6.10 kernel, over on the mature EXT4 file-system side the changes are mostly small. There are some minor changes, more folio conversion work, and also adding support for the FS_IOC_GETFSSYSFSPATH ioctl that has been seeing some standardization and adoption by the common Linux file-systems.

Firewire IEEE-1394 Support Continues To Be Improved With The Linux 6.10 Kernel
16 May 06:16 AM EDT - Hardware - Linux 6.10 + Firewire - 5 Comments

While most of you have not thought about or used Firewire (IEEE-1394) in years, there still are some legacy digital video cameras and some professional audio devices relying on the interface. Last year saw a new Firewire maintainer step-up for the Linux kernel after the code had fallen dormant. The plans by that new maintainer, Takashi Sakamoto, are to maintain Linux's Firewire support through 2029. He's continuing to do a good job with the upcoming Linux 6.10 kernel bringing the latest batch of Firewire enhancements.
