Similar to what I have shown with the Ryzen 9 7950X AVX-512 desktop performance and AMD EPYC 9004 series AVX-512 server performance, the new Ryzen 7040 series mobile processors are exhibiting great AVX-512 performance for laptops. In today's article is a look at the performance impact when toggling AVX-512 capabilities for a Ryzen 7 7840U "Phoenix" SoC compared to toggling AVX-512 with prior Intel Tiger Lake and Ice Lake laptops that offer AVX-512.

Intel's Linux software engineers understand the annual GCC compiler release cadence well and acknowledge the importance of having tuned compiler support available at launch. Intel for years has tended to get their new CPU support and new ISA features upstreamed into GCC as well as LLVM/Clang well ahead of product launch so that by the time their new consumer and server CPUs are shipping, there tends to be support within compilers just not at their stable versions but already found in the likes of Ubuntu. With that said, today Intel engineers posted initial compiler patches for Lunar Lake and Arrow Lake processors...

While less than one week has passed since the Linux 6.5 merge window ended and 6.5-rc1 being issued, there is already the first set of drm-misc-next changes submitted to DRM-Next of early open-source graphics/display driver changes geared for Linux 6.6 later this year...

Now that the Linux 6.5 merge window ended this past weekend, here is the usual Phoronix overview that lists all the prominent new features and changes coming for this next version.

Last month AMD Linux kernel driver patches revealed a new feature called FreeSync Panel Replay that is basically an improvement over Panel Self Refresh (PSR) for laptop displays. That code didn't make it for the recently-closed v6.5 merge window but this week AMD engineers did post a second iteration of the patches...

With the ASUS ROG Ally being the first device powered by AMD's new Z1 Extreme SoC with Zen 4 CPU cores and RDNA3 graphics, it's been very interesting to see its performance advantages over the Steam Deck. But beyond its potential for use in gaming handhelds, it's quite fascinating to see how powerful the Z1 Extreme actually is when removing power restrictions on this SoC. In this article is a wide range of CPU benchmarks putting the Z1 Extreme up against the new Ryzen 7 7840U laptop SoC as well as prior generation Ryzen 7 PRO 6850U for reference. When adjusting the ACPI Platform Profile configuration, the Ryzen Z1 Extreme proves to be very robust from a low-power SoC delivering good battery performance up through pulling 50+ Watts while outperforming the 7840U.

While GIMP 3.0 stable likely not set to debut in 2023 but rather at least release candidates are expected, Canonical is looking at shipping a GIMP 3.0 snapshot in Ubuntu 23.10 in hopes of GIMP 3.0 stable by the time of Ubuntu 24.04 LTS or at least a near final v3.0 state...

Mesa's Radeon Vulkan driver "RADV" supports native hardware ray-tracing with RDNA2 and RDNA3 graphics cards where it's matured quite nicely over the past number of months. With the upcoming Mesa 23.2, RADV RT support is enabled by default for all supported GPUs. RADV also has emulated ray-tracing support for older generations of AMD GPUs and as of today it's finally hit a 100% pass rate...

Earlier this month I provided some initial GeForce RTX 4060 vs. Radeon RX 7600 Linux gaming benchmarks for this new sub-$300 graphics card. For those considering this latest Ada Lovelace graphics card for 3D rendering or compute purposes, here are some benchmarks of the GeForce RTX 4060 on that front by looking at the generational performance of the x060 series graphics cards from the RTX 4060 back to the GTX 1060.

Following the stunning decision last month by IBM that they would begin limiting access to the Red Hat Enterprise Linux sources, AlmaLinux quickly came out working on a path forward and Rocky Linux also shared some ideas how they may continue providing a RHEL-compatible Linux distribution. We've been waiting for Oracle to comment on their plans for the RHEL-compatible Oracle Linux distribution and today they finally issued a statement...

Besides Bcachefs missing out on Linux 6.5, another patch series that didn't get buttoned up in time for the v6.5 merge window was AMD's work on radio frequency interference (RFI) mitigation between WiFi 6/6e/7 hardware and AMD's newest SoCs with RDNA3 graphics...

About a year ago Ubuntu changed its default compression level for its initramfs handling down to Zstd level one to deal with slow initramfs creation times on low-end systems / development boards. But since then that has resulted in larger initramfs sizes and yielding other bugs like more quickly filling up the /boot partition on Ubuntu systems. Thus the developers have gone back to the drawing board and are trying to figure out a path forward for better initramfs handling that works well for low-end single board computers while also maximizing space savings and working out well for all Ubuntu use-cases...

While Google shutdown their Stadia game streaming service, with updated firmware there is Bluetooth (BLE) support for the controller as well as USB wired connectivity for those wishing to continue using this gaming controller.

The Intel Xeon Max 9480 flagship Sapphire Rapids CPU with HBM2e memory tops out at 56 cores / 112 threads, so how can that compete with the latest AMD EPYC processors hitting 96 cores for Genoa (or 120 cores with the forthcoming Bergamo)? Besides the on-package HBM2e that is unique to the Xeon Max family, the other ace that Xeon Max holds with the rest of the Sapphire Rapids line-up is support for the Advanced Matrix Extensions (AMX). In today's benchmarks of the Intel Xeon Max performance is precisely showing the impact of how HBM2e and AMX in order to compete -- and outperform -- AMD's EPYC 9554 and 9654 processors in AI workloads when effectively leveraging AMX and the onboard HBM2e memory.
