Earlier this week I delivered initial Intel Xe2 Lunar Lake graphics benchmarks on Linux while today the focus is on Lunar Lake's CPU performance. The Xe2 graphics performance under Linux was disappointingly slow with it performing even worse than Meteor Lake while RDNA3.5 graphics led. Intel has been investigating the Xe2 Linux graphics performance but I haven't heard any updates yet. Today the attention is on the Lunar Lake CPU side under Linux and it too isn't looking too good. The performance of this 8-core Core Ultra 7 256V SoC is poor in real-world multi-threaded scenarios and the performance-per-Watt is only compelling in a subset of workloads. The AMD Ryzen AI 9 365 and AMD Ryzen AI 9 HX 370 Zen 5 SoCs tended to deliver the superior performance and power efficiency under Linux.

The open-source ZLUDA project began life as a drop-in CUDA replacement that ran atop Intel GPUs using the Level Zero API. Then AMD quietly began funding it for several years as a viable CUDA implementation running atop AMD GPUs until discontinued funding earlier this year. ZLUDA for AMD GPUs was then made open-source but then in August the ZLUDA code was removed at AMD's request. Today it's taking on its third incarnation...

Last week when kicking off the Intel Granite Rapids benchmarking with the Xeon 6980P processors there was particularly strong performance within HPC and other scientific computing workloads. Besides going now up to 128 cores / 256 threads per socket, another reason for the especially strong generational uplift and against the current AMD EPYC competition is Xeon 6 Granite Rapids introducing Multiplexed Rank memory support. One of the areas I've been eager to explore is quantifying the DDR5-6400 vs. MRDIMM 8800MT/s performance difference and this article is dedicated to looking at that memory performance impact for the Xeon 6900P series.

Last week with the launch of the Intel Xeon 6900P "Granite Rapids" processors, Intel didn't disclose their list prices... Today they added the Granite Rapids list prices to their ARK database. With Granite Rapids making Intel much more competitive to the AMD EPYC competition and over prior generation Xeon CPUs, these new processors are commanding a higher price tag with the Xeon 6980P topping out at $17,800 USD...

After years of AmpereComputing talking about AmpereOne AArch64 server processors, it looks like we are finally on the cusp of seeing broader availability of the processors and servers/motherboards for this ARM server platform up to 192 cores. At the end of August I finally received a temporary review system with the AmpereOne A192-32X flagship SKU. That server was the Supermicro ARS-211M-NR and is supposed to be seeing availability real soon. Now the latest on the AmpereOne front is Giga Computing (Gigabyte) announcing general availability of their servers...

With the recent Intel layoffs and early retirement / buyout packages, I have been curious to see what impact it will have on the open-source/Linux software engineers at the company. There's at least a few driver maintainers that have unfortunately departed the company but at least no major exodus of their well respected Linux software engineers...

The Redox OS open-source Rust-written operating system project has published their September 2024 status update...

With the Intel Xeon 6900P "Granite Rapids" processors that launched last week there are SNC3 and HEX clustering modes for these new processors. The default Sub-NUMA Clustering 3 (SNC3) mode for the three compute dies while the HEX mode is like SNC1 mode formerly for all three compute dies acting as one NUMA node. Using the flagship 128-core Intel Xeon 6980P processors, I ran some benchmarks looking at the real-world performance difference for SNC3 vs. HEX clustering modes on Granite Rapids.
