AMD Strix Point Linux Performance Comparison One Year After Launch
The Firefox web browser performance on AMD Strix Point shot up by some 46% over the past year. While there have been Firefox updates in that time, the improvement here is most likely attributed to the AMD P-State improvements merged to the mainline Linux kernel over the past year.
The Ryzen AI 9 HX 370 peak CPU power consumption was similar then and now at 32~33 Watts but the average while running last year at launch was 11 Watts and now is up to around 15 Watts. Again likely due to P-State changes and the web browser ending up on the Zen 5 cores rather than Zen 5C, but when factoring the performance-per-Watt it's still an improvement over where it was at launch last year.
The web browser performance -- and many other single-threaded workloads -- being faster now with the latest Linux software stack was seen across other browser benchmarks too with just slightly higher CPU power use on average.
While the single/lightly threaded workloads were seeing slightly higher power use when running on the up-to-date Linux software stack for this ASUS Zenbook laptop with Strix Point, the multi-threaded workloads at the defaults were tending to see slightly lower performance but with lower CPU power use on average yielding providing greater efficiency.
In some of these multi-threaded workloads with the newer Linux software stack the AMD Ryzen AI 9 HX 370 CPU power use dropped by 3~4 Watts on average but came out with better performance-per-Watt than when these Strix Point laptops began shipping last year. For those not wanting to lose any raw performance, there is always the performance platform profile mode for maximizing the performance over power.
