Linux Address Space Isolation "ASI" Revived After Lowering 70% Performance Hit To 13%

Several years ago Google engineers began exploring address space isolation for the Linux kernel and ultimately proposing Linux ASI for better dealing with CPU speculative execution attacks. While the hope was it would better cope with the ever growing list of CPU speculative execution vulnerabilities, the effort was thwarted initially by I/O throughput seeing a 70% performance hit. That level of performance cost was unsustainable. But now that I/O overhead has been reduced to just 13%...

AMD Ryzen AI Max+ 395 With Framework Desktop vs. Intel Core Ultra 9 285K Linux Performance

Last week alongside our Framework Desktop review with the AMD Ryzen AI Max+ 395 "Strix Halo" SoC I posted benchmarks of the Strix Halo performance compared to the Ryzen 9 9950X / 9950X3D socketed desktop processors. For those wondering similarly how the top-end Strix Halo SoC in the Framework Desktop competes with the Intel Core Ultra 9 285K "Arrow Lake" flagship in performance and power efficiency, here are those comparison benchmarks.

Early Linux 6.17 Tests Show Some AMD Strix Halo Performance Improvements & Regressions

Even prior to the Linux 6.17-rc1 release on Sunday I already had kicked off some Linux 6.17 Git benchmarking in being eager to see how the performance is beginning to shape up for this next kernel release that is set to power the likes of Ubuntu 25.10 and Fedora 43. There is some good news and bad news with my early testing on the ZBook Ultra G1a for AMD Strix Halo...

Intel Posts Latest Patches For DRM Sharpness Property To Enjoy With Lunar Lake & Beyond

For over a year now Intel has been working on a new DRM sharpness property for making use of Lunar Lake's new adaptive sharpening filter capabilities built into its display engine. This new sharpening filter with Lunar Lake and future SoCs can hep with sharpening blurred or upscaled content and over the past year has gone through several rounds of code review. The latest patches were sent out last week for this DRM sharpness property...

AMD EPYC 4545P Achieves 2.24x The Performance At Half The Power Of The First EPYC CPU

Recently we looked at the performance of the AMD EPYC 4545P that is a 16 core 65 Watt processor in the EPYC 4005 "Grado" series. This is quite an interesting processor for those after low-power servers, edge AI deployments, and other purposes with no similar Ryzen 9000 series processor or competition from Intel offering sixteen performance cores at around 65 Watts. Complementing all the performance and power data from that review article, here are some additional tests putting its performance and efficiency compared to the original AMD EPYC 7601 flagship processor that ushered in the EPYC family eight years ago.
