Intel Core i7 1185G7 Linux Performance

After seeing so many losses by the i7-1185G7 Dell XPS 13 against the i7-1165G7 Dell XPS 13, I did follow up with some more benchmarks on both of those laptops...

Especially for graphics but carried through in other workloads too, the i7-1165G7 was better. For those secondary runs the benchmarks were carried out while also monitoring the peak CPU core frequency (the highest frequency found on any of the cores), the CPU package power consumption exposed via RAPL, and the CPU core temperature.

This follow-up run did confirm both the i7-1165G7 and i7-1185G7 hitting up to 4.7GHz reported under Linux but with the i7-1185G7 not hitting the advertised 4.8GHz maximum frequency. Interestingly the average CPU peak frequency found with the i7-1165G7 was indeed higher than the i7-1185G7. Both Tiger Lake SoCs had an average power consumption reported by RAPL around 22 Watts with a peak of 75~78 Watts. Within the Dell XPS, both Tiger Lake processors had an average core temperature during these benchmarks of 68 degrees with a peak of 100 degrees.

Whether it's due to a defect with Linux like the P-State CPU frequency scaling driver or some other component or an issue with the Dell XPS 13 9310 either for thermal reasons or otherwise some system firmware oddity is yet to be determined. But from these initial Linux results with Ubuntu 21.04, there at least isn't much advantage with this current showing to go for the i7-1185G7 over the i7-1165G7 unless needing TXT or TME functionality. Stay tuned for further tests exploring Tiger Lake power management on Linux and other investigative benchmarks.

Those wanting to see this additional i7-1165G7 vs. i7-1185G7 data with thermal/power/clocking metrics can do so via this extra result file.

Especially if frequently running any multi-threaded workloads, the AMD Ryzen laptop processors have a lot to offer. Even with only having access to the Ryzen 5 5500U (Zen 2) processor at the moment of their 5000 series line-up, it easily outperformed the Tiger Lake U processors in those threaded real-world workloads. It will be really interesting to see how the Linux performance compares once finally getting my hands on any Zen 3 laptop models particularly for seeing how the single-threaded Linux performance compares against Tiger Lake.
