Following last week's launch testing of the Intel Core Ultra 9 285K and Core Ultra 5 245K Arrow Lake desktop processors, the next area I've been exploring deeper has been the DDR5 memory performance including with CUDIMMs. Here's a closer look at the Core Ultra 9 285K performance under Linux while testing several different sets of memory and running Ubuntu 24.10.

Going back to earlier in the year AMD Linux engineers have been prepping the kernel for PCI Express TLP Processing Hints (TPH) support that allows for hints that can be injected to improve latency and lowering traffic congestion when there are several possible cache locations on the server with the TPH noting the optimal location of a Transaction Layer Packet (TLP). This PCIe TPH support is set to be merged upstream with the forthcoming Linux 6.13 cycle...

Intel merged Linear Address Masking into the Linux kernel last year as a means of allowing user-space to store metadata within some bits of pointers without masking it out before use. LAM can be useful for virtual machines, sanitizers / profiling / memory tagging, and other uses. While the brand new Intel Arrow Lake and Lunar Lake CPUs support LAM, the Linux kernel is now disabling LAM out of security concerns...

For the past year Intel software engineers have been developing a PCIe cooling driver to reduce the PCIe link speed to cope with thermal issues.

Back in 2020~2021 there was lots of talk and work around FUTEX2 for improving the Linux kernel's Futex implementation for fast user mutex. The FUTEX2 work was driven in large part for helping Steam Play / Wine gaming by better matching the behavior of Microsoft Windows with its WaitForMultipleObjects handling. While the initial code landed back in Linux 5.16, there's been other remaining FUTEX2 features still desired like variable-sized futexes and NUMA-awareness. Finally now we're seeing that work revived...

When a number of Russian Linux developers were removed from their MAINTAINERS file in the Linux kernel, it was described as due to "compliance requirements" but vague in what those requirements entailed. Linus Torvalds then commented on the Russian Linux maintainers being de-listed and made it clear that they were done due to government compliance requirements / legal issues around Russia. Now today some additional light has been shed on those new Linux kernel "compliance requirements"...

Earlier this month Intel announced the Core Ultra 200S "Arrow Lake" processors and today they go on sale. In turn, the review embargo also lifts for these new desktop processors. Up first today on Phoronix is the Intel Core Ultra 9 285K Linux performance review for this flagship 24-core desktop processor.

For the recently launched AMD EPYC 9005 series "Turin" processors there is good support out-of-the-box running on the likes of Linux 6.8 as found with Ubuntu 24.04 LTS. The one exception is if wanting to engage CPU power monitoring you need a RAPL/PowerCap patch that was just upstreamed in v6.12. But what about using a newer kernel for greater performance in light of all the upstream optimizations to the kernel in general? Here are some Linux 6.8 vs. 6.11 vs. 6.12 kernel benchmarks on a dual AMD EPYC 9755 server...

That use has continued to grow and an unofficial estimate now puts it at around one billion RISC-V cores shipping in 2024 NVIDIA chips...

Following the launch of the Raspberry Pi AI Kit back during the summer with up to 13 TOPS performance for AI inference, the Raspberry Pi AI HAT+ was announced today with up to 26 TOPS capabilities...

Following the ASUS AIPT patch posting this weekend from an Intel Linux engineer that was analyzing my previously-published Lunar Lake results showing rather poor performance on the ASUS Zenbook S 14, the performance has been looking much better. On Monday I posted updated Intel Xe2 graphics results showing strong uplift now that the ASUS Lunar Lake laptop was operating in its standard mode rather than whisper mode. In today's article is data from more than 400 CPU/system benchmarks to see how the Core Ultra 7 256V performance has improved with this new Linux kernel patch and compared to the prior AMD Ryzen and Intel Core laptop comparison data.
