Windows 10 vs. Ubuntu 20.10 Performance With Intel Tiger Lake, AMD Renoir

[Hibbelharry]

These tests look a bit funny. The intel CPU is intels current mobile high performance offering, meanwhile the AMD ryzen 4500u is more like their midrange, low power product, so AMD looks bad when there is no necessity here.

Except we have no real data about Windows mitigations. Furthermore, it may be glibc crippling performance. Not for the first time..

Does GNU secretly support Intel?

Just using the hardware I have available.... (The 4700U I use as my main system so normally just 4500U for Renoir testing.)

amd linux need more work, not a surprise, intel always support much better linux then amd, even today some features come after years

I doubt, but years ago their malloc library was far from optimal in some cases. I wouldn't be surprised if there are still some problems in optimizations.

Win10 2009 was just released...

Win10 2009 was just released...

So "just" that it's still not available to a lot of users, because Microsoft do love their staggered rollouts.

OK, so the .iso can be downloaded, etc... but benchmarks take time to run!

Speaking of Windows, Edge for Linux was launched in preview form. I took it for a spin to do what it is used for on windows and, surprise, it didn't started Chrome download on Google's website. Purposeful or only a innocent glitch? Firefox can be downloaded normally, though.

I took it out for a spin as well. Tried running it in Ozone Wayland mode and the browser failed to run with an Illegal Instruction. On both Gnome Shell 3.30 and Plasma 5.14 as bundled by Debian 10.

Works fine in Classic mode and in Ozone X11 mode but it means nothing to me since I run a Wayland desktop. Come on MS, stop using that antique display system. Even Chromium in Ozone Wayland mode can run on my old Plasma 5.14 if i disable GPU acceleration. This is not acceptable.

Back to Chromium and Firefox for now.

20.10 hasn't been officially released as well so Michael is probably going to run it again anyway

Windows good for AMD
Linux good for Intel

Does not look really that way, on the contrary both CPUs seem to perform better in Linux than Windows generally.
Both AMD and Intel have nice performance bumps when the same workload is run under Linux than Windows, just a couple of specific benchmarks are mixed bags.
