Phoronix: Benchmarks: AMD Ryzen 7000 Series Performance Boosted With Ubuntu 23.10

With Ubuntu 23.10 due for release on Thursday, I've been benchmarking a number of systems to look at the Ubuntu 23.10 performance against prior releases like Ubuntu 23.04 and Ubuntu 22.04 LTS. Besides the open-source graphics driver performance for Intel and AMD Radeon graphics always being a stand-out improvement, one area that is particularly exciting with Ubuntu 23.10 is for those with newer AMD processors where there are some nice performance gains to find with this new Ubuntu Linux release. Here are side-by-side benchmarks of an AMD Ryzen 9 7950X desktop along with an Intel Core i9 13900K desktop while testing Ubuntu 22.04.3 LTS / Ubuntu 23.04 / Ubuntu 23.10.

I will be even better with 6.6.

Why can amd beat intel in everything that requires raw force (i.e. processing power), but suck so much at browser benchmarks? Javascript jit favors intel scheduling?

Likely the result of aggressive single-core boosting behaviour in conjunction with higher clockrates.

Not only this, but also: Photoshop, Lightroom, Premiere Pro, After effects, sometimes 7950X loses by more than 30% and consumes more energy.

That's why, because not every filter or effect in these programs takes up all cores.

Additionally, the hardware encoders in AMD are also much weaker than Intel Quick Sync.

More performance and less power consumption, it seems all good. You said similar gain should be obersvable for zen 2 and 3?

After my kernel upgrade and using pstate my cpu finally can downclock to 550MHz.

Tbh I consider that way more important than the few percentage of more performance

The AMD cores consume also more power, i.e. they're doing _something_, more than the intel cores, and yet
the results show their work is for naught, which is surprising since recent Zen have very good power management features
and perf/watt in the "usual" phoronix benchmarks is above intels.
Yes intel cores can boost better, but their power consumption is usually (i.e. seen on other benchmarks in the past)
also significantly higher than amds when they do that.

using AMD P-State EPP (active mode) with the powersave governor rather than ACPI CPUFreq with the Schedutil governor

Sad that even powersave is better than schedutil, but Ubuntu has another improvement waiting if they switch to performance on the next release.

Has anyone noticed that with EPP active on powersave, singlecore load doesn't raise frequencies? If I load up all cores it even gets above base clock but a single core stays below 1 GHz. Or is this buggy behavior from my platform?
