Core i3 10100 vs. Core i5 10600K vs. Ryzen 3 3300X Linux Gaming Benchmarks

Last month on Phoronix were 350+ benchmarks of the AMD Ryzen 3 3300X vs. Intel Core i3 10100, including a number of Linux gaming performance tests. Following that I also ran some tests with the Core i5 10600K tossed in for those that may be weighing between the Ryzen 3 / Core i3 vs. Core i5 for gaming. Here are those additional data points...

SWVKC Is A Vulkan-Powered Wayland Compositor Focused On Performance + Correctness

While the current Vulkan API is exhaustive enough to implement full-featured Wayland compositors and X11 window managers, to date there hasn't been too much adoption considering OpenGL is still more pervasive among hardware/drivers and it's obviously a significant effort writing a new compositor from scratch. One of the leading (among few) examples of a Vulkan-powered window manager / compositor is ChamferWM, which does continue to be developed. SWVKC meanwhile is one that has been seeing development this year as an alpha-stage Wayland Vulkan compositor...

Linux Kernel Prepping To Make Use Of Intel's New SERIALIZE Instruction

As outlined a few months ago, Intel's future Sapphire Rapids and Alder Lake processors are set to add a SERIALIZE instruction. That SERIALIZE instruction ensures all flags/register/memory modifications are complete as well as draining all buffered writes to memory before the next instruction is executed. Linux is moving forward with preparing to make use of this new CPU instruction in its function for stopping speculative execution and prefetching of modified code...
