Earlier this month I provided benchmarks showing the Intel UHD Graphics 770 with Alder Lake compared to other CPUs/APUs under Linux. Those tests were done with the latest open-source Intel Linux graphics driver code at the time, but for those running Alder Lake and wondering if it's worthwhile moving from the stable versions to more bleeding-edge components, this article is for you.

This issue led to memory leaking from one process to another and only uncovered by accident. To address this class of memory corruption issues moving forward, Google is proposing a new "Page Table Check" feature moving forward...

Linux 5.16-rc1 is coming out later today and already I'm seeing some fallout in the new kernel's performance... In particular, bad news for Alder Lake that is already seeing the Linux performance trailing Windows 11 seemingly due to the lack of Thread Director integration right now in the kernel and any other missing optimizations around Intel's hybrid architecture. A new feature of Linux 5.16 is unfortunately having unintended regressions for Alder Lake with at least the flagship Core i9 12900K. Here are the results from the latest kernel bisecting that uncovered this latest upstream slowdown.
