While I have been very eager to test out the Core Ultra 200V Lunar Lake series on Linux in part due to the new Xe2 integrated graphics, after several days of pushing a new Lunar Lake laptop on Linux the results have been very disappointing. Besides needing a very leading-edge software stack to enjoy the Xe2 accelerated graphics out-of-the-box, the performance currently is poor. It's a fraction of the Windows performance and currently falls behind the Meteor Lake graphics performance and in turn also being well behind the AMD RDNA3.5 competition with the Ryzen AI 300 series laptops.

The newly-merged sched_ext allows for the Linux kernel scheduler to be made more extensible by allowing BPF programs to be loaded to affect the kernel's scheduling behavior. There's now a similar take on CPU frequency scaling: cpufreq_ext. There's a "request for comments" patch series on cpufreq_ext for making extensible CPU frequency scaling algorithm adaptations with BPF...

Earlier this week in the launch-day Intel Xeon 6980P Granite Rapids review/benchmarks I unfortunately wasn't able to provide any CPU power consumption and performance-per-Watt benchmarks due a Linux kernel issue and the minimal time ahead of launch for testing. I've now repeated the Xeon 6980P benchmarking on the Linux 6.8 kernel of Ubuntu 24.04 LTS with power monitoring working and have those power efficiency numbers to share today for how Granite Rapids compares to prior Emerald Rapids / Sapphire Rapids / Ice Lake and against the current AMD EPYC Bergamo/Genoa(X) competition.
