Intel Core i7 1185G7 Linux Performance

All of the laptops tested were running Ubuntu 21.04 with the Linux 5.13 kernel and Mesa 21.2-devel for providing a bleeding edge look at the Linux performance across all of these tested processors. Again, tested laptops/processors based on what I had available. All settings at the OS defaults.

In the CPU benchmarks, between the Core i7 1165G7 and i7 1185G7 it was a rather somewhat wash of results with commonly seeing no measurable difference between these Tiger Lake processors even with the advertised clock differences. At least within the Dell XPS 13 9310, it's rather thermal limited.

While the Ryzen 5 5500U makes use of Zen 2 CPU cores, with its six cores / 12 threads it easily dominated the other available laptop CPUs under test in multi-threaded workloads.

When taking the geometric mean of 180 different CPU-focused tests, the Core i7 1185G7 was less than 3% faster than the i7-1165G7.

For the web browser benchmarks, for example, within Google Chrome and Mozilla Firefox the i7-1165G7 tended to reliably deliver better performance than the i7-1185G7 at least under Linux with this up-to-date software stack...

For chess benchmarks with TSCP, Stockfish, and Asmfish, the Ryzen 5 5500U easily delivered much better performance thanks to its extra cores/threads. Unfortunately the Ryzen 5 5500U is the highest-end Ryzen 5000 series mobile processor I currently have available.

Similarly, for code compilation tests even the prior generation Ryzen 5 4500U pans out better than the Core i7 1185G7 thanks to having six physical cores. The timed build tests used were compiling the Linux kernel, GDB, Godot, Wasmer, and Mesa.
