While the Intel Extreme Tuning Utility (XTU) on Windows allows for undervolting laptop processors, currently on Linux there isn't any Intel-endorsed way for undervolting your CPU should you be interested in better thermal/power efficiency and other factors. But a hypothetical Linux kernel driver could be coming for filling such void...

Stemming from our initial Intel Core i7 1165G7 "Tiger Lake" benchmarks on the Dell XPS 13 9310 last week and then also discovering better single-threaded performance on Ubuntu 20.10, one of the pressing questions was whether this is expected performance on Linux or if it's coming up short of Microsoft Windows for this first tier-one notebook to market with Intel Tiger Lake. So following those earlier tests I proceeded to do a Windows 10 Pro with all available updates comparison on Ubuntu 20.10 with the i7-1165G7. For added context, the same software stack and tests were repeated on an AMD Ryzen "Renoir" notebook.

Intel has begun adding support for Alderlake-S to their open-source Linux kernel graphics driver...

Facebook's BOLT is a multi-year project focused on speeding up the performance of binaries. This open-source project initially focused on being able to better optimize Linux x86_64/ARM64 ELF binaries as a post-link optimizer. BOLT has been seeing much success with even Google using it now for better performance and now there is work to upstream it as part of the LLVM project...

It was just on Monday that Intel's talented open-source developers merged a hefty Tiger Lake graphics optimization into the Mesa 20.3 code that for some games/software can be around ~11% faster thanks to greater caching. Just a day later another optimization has arrived for helping these latest-generation Intel graphics...

This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus...

With Ubuntu 20.10 due for release this week I have begun testing near-final Ubuntu 20.10 builds on many more systems in the lab.

From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake...

Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.
