With Intel's just-launched 5th Gen Xeon "Emerald Rapids" processors headlined by the 64-core Xeon Platinum 8592+, one of the key upgrades with these new server processors is now supporting DDR5-5600 memory compared to DDR5-4800 with Sapphire Rapids and also the memory frequency limit with AMD's EPYC Zen 4 processors. Here are some benchmarks of the flagship Xeon Platinum 8592+ when being tested with DDR5-4800 versus DDR5-5600 memory modules.

Following the 5th Gen Xeon Scalable "Emerald Rapids" overview, you are likely wondering about the performance claims made by Intel and how they shake up in independent testing as well as how Emerald Rapids competes against AMD EPYC Genoa(X) and Bergamo. If so this article is for you with the Phoronix benchmarks of the new flagship Intel Xeon Platinum 8592+ 64-core processors being tested in both single and dual socket modes.

In addition to announcing the Core Ultra "Meteor Lake" processors, Intel's AI Everywhere event in New York City also served as the launch point for 5th Gen Xeon Scalable "Emerald Rapids" server processors. Emerald Rapids is an incremental improvement over Sapphire Rapids with emboldened AI capabilities, energy efficiency improvements, and now up to 64 cores per socket.

While Intel's AI Everywhere event today was primarily focused on Core Ultra "Meteor Lake" laptop processors and 5th Gen Xeon Scalable "Emerald Rapids" processors, Intel also briefly announced their newest Xeon D and Xeon E series processors...

At Intel's AI Everywhere event they officially launched their new Core Ultra branded Meteor Lake processors that will begin appearing in new laptops. Intel Core Ultra aims to deliver their most power efficient client processors, deliver around twice the GPU performance of existing integrated graphics, and via the NPU feature more robust AI capabilities.

There's been nothing new on the BUS1 front this year for capability-based IPC within the Linux kernel... In fact, the BUS1 out-of-tree kernel module has gone untouched for years now. But out of the BUS1 project has been Dbus-Broker for a high performance D-Bus message broker in user-space that doesn't break existing D-Bus compatibility. Out today is the newest version of that project closely tied to systemd developers...

Canonical has decided for Ubuntu 24.04 LTS that they will now enable frame pointers by default when building packages. There will still selectively be some packages where they decide to disable frame pointers due to the performance overhead, but the focus on this change is to improve the out-of-the-box debugging and profiling support on the Linux distribution...

The X.Org Server doesn't see much in the way of feature work these days with Red Hat and others divesting from classic X.Org/X11 sessions. But there continues to be new point releases of the X.Org Server and the XWayland code due to long-standing security issues within the X.Org codebase. New point releases were out last night due to two CVEs for bugs dating back to 2007 and 2009...

A few months ago I wrote about AMD Linux engineers working on ACPI PHAT support for the Linux kernel. This week new patches around Linux ACPI PHAT handling have been posted with further confirmation of this functionality coming to "future" AMD SoCs...

With Intel's very timely upstream Linux hardware support going back years, they typically start on the upstream hardware enablement well in advance of the product's planned public launch. On a number of occasions this has meant adding support to the Linux kernel for hardware that never ends up being released to consumers. There's been recent cases like the Thunder Bay support that was dropped from the kernel after it became clear that the SoC would never ship to now a more extreme case of a driver being in the mainline kernel for 15 years to support never-released hardware...

The Linux kernel's thermal driver has the obvious notion of hot and critically-hot trip points while to this point there hasn't been the opposite: cold trip points (events) but that's finally been proposed as we approach the end of 2023...

SVT-AV1 v1.8 was released this week as the newest version of this open-source AV1 video encoder originally started by Intel and continues to be developed by Intel engineers in cooperation with the Alliance for Open Media. As with most releases, optimizing this CPU-based AV1 encoder's performance continues to be a key priority...

Canonical is experimenting with x86_64 micro-architecture feature levels! They have produced an experimental build of Ubuntu Server using x86_64_v3 for requiring basically Intel and AMD CPUs with AVX capabilities. But they aren't yet committing to it as a default or when such a change may materialize...

Since the release of the Threadripper 7000 series on 20 November I've carried out and published many benchmarks of these new HEDT/PRO CPUs including the flagship AMD Ryzen Threadripper PRO 7995WX featuring 96-cores / 192-threads. All of my Threadripper PRO 7995WX benchmarks have been carried out using an HP Z6 G5 A workstation and it's proven to be an outright beast for creators, software developers, and others needing immense multi-threaded capabilities at your finger tips. Here's more about my experience with this new high-end HP workstation.

With Linux 6.7 there's now support for enabling/disabling 32-bit program support at boot-time. The "ia32_emulation=" argument can be used for enabling/disabling 32-bit user-space program support and the ability to support 32-bit system calls. Right now when forcing off the x86 32-bit support it can be confusing if the user is unaware as no warning is currently provided, but that is about to change...

The long-in-development work for a fully-functional multi-threaded FFmpeg command line has been merged! The FFmpeg CLI with multi-threaded transcoding pipelines is now merged to FFmpeg Git ahead of FFmpeg 7.0 releasing early next year. FFmpeg is widely-used throughout many industries for video transcoding and in today's many-core world this is a terrific improvement for this key open-source project...

Linux 6.6 brought an initial Intel Visual Sensing Controller "IVSC" driver. The Intel IVSC drivers have long been out-of-tree for use with Alder Lake laptops and newer. Linux 6.7 brought the La Jolla Cove Adadpter driver code as part of the IVSC controller. With Linux 6.8 there's yet more work landing on the IVSC front...

While it's been three years now since Ampere Altra Q80 was first introduced and two years since first testing the 128-core Ampere Altra Max, this ARM server platform has aged rather well with more robust hardware platforms coming to market with better firmware, the AArch64 Linux/open-source software ecosystem as a whole improving a lot during this time and more open-source projects receiving ARM optimizations, and other improvements made. While we're eagerly awaiting to see AmpereOne hardware, here is a look at how Ampere Altra Max M128-30 is standing up against current AMD EPYC Genoa(X) and Bergamo server CPUs along with Intel Xeon Scalable Sapphire Rapids processors in raw performance and power efficiency.
