When Windows Picks Favorites...

Windows is funky and AMD on Windows 11 has been even funkier.

Zen 5 CPUs launched and it has been rough- most everything was very underwhelming. Also, data was conflicting between AMD themselves and reviewers which lead to some interesting discoveries... that didn't change Zen 5, but made a realization that Windows has some issues with AMD CPUs. So, I tested it. 3 versions: Current Windows 11 (23H2) with and w/o the branch prediction patch, and the Windows 11 24H2 Preview Build. I did this on 3 different CPUs: an R9 5900x, R7 7800x3D, and i7 13700k- to get a wide variety of how this performs. THE RESULTS ARE WILD.

How long has Microsoft known this? Are they trying to hide that performance has been worse? Is Windows picking favorites???

AMD beating intel with fucking weighted clothes on.

[polvocorrupto]

Remember Intel denying that Intel Compiler executable was slowing AMD chips but yet they tried to hunt down the enthusiasts who modified it to make Intel Compiler Patcher to bypass the performance crippling on AMD chips?

[FantomasARM]

Micro in Microsoft stands for the amount of effort they are doing to optimize their software.

[Erowens]

Isn't it funny how pretty much every time Microsofts OS accidentally works better on one brands silicon than another, its always intel?

[zen]

7800x3d is so powerful that it made Intel ask Windows for help, AMD is doing things right

[seeratlasdtyria]

MOST of you guys are too young to remember..."WinTel", formerly a very commonly used moniker---for a REASON!

[DragonOfTheMortalKombat]

Intel can't get stable CPUs so they decided to use Wintel strategy lol.

[defectiveclone]

Microsoft and intel are always working close together. AMD gets second rate service.

When I was a kid, I used to hate how Windows gives a lot of bloatware, add that with having an AMD hardware, I've searched on forums that Windows intentionally sabotages AMD hardware. And now this video comes and good thing my hunch was right.

I can actually answer why AMD didn't catch this issue with testing: in-depth hardware testing on Windows _requires_ elevated admin privileges. To run all the necessary tests, these companies use custom devices with custom drivers (which are invariably unsigned). For any automated test workflow, running a queue of varied testing protocols on a system without elevated permissions is a non-starter. It would be practically impossible for AMD to see this issue coming because they would have to basically sabotage their testing system to do so. I certainly doubt they expected the OS to actually throttle CPU functionality outside of elevated mode.

As for my experience, I was contracted to Nvidia for about a year to set up and troubleshoot setups used to automate GPU hardware tests. We always turned off test-signing requirements and otherwise had the client PCs run with elevated privileges because Windows would prevent our tests from running correctly otherwise (these machines basically had to be as _unsecured_ as possible).

P.S. We had to use Windows 11, which seemed fine at first, but then it started preaching about the carbon footprints in the settings while requiring an extra click and mouse movement (or extra keyboard movement) to open the _real_ context menu. This is yet another reason to continue avoiding it.

Microsoft forcing AMD users to become Linux enthusiasts? I see this as an absolute win!

[grtitann]

Microcrap has been doing this forever.
Remember how conveniently, they couldn't release Win XP 64 until Intel was ready yet ignored the already released AMD Athlon 64?
Yeah, they are not called Wintel for nothing.

[phillysupra]

I've said it from day one. Windows 11 was specifically written for Intel 12th gen

[metatron]

This is absolutely grounds for Antitrust.

[Gatorboy]

Such a shame Windows has a monopoly on the gaming space. You wanna play games? Download Windows! You wanna do anything gaming related? Windows!

[abbottshaull]

Remember how Microsoft would intentionally make software run slower in Windows so they could buy them out add them to Microsoft line up. So no it doesn't surprise me at all.

[mm-ytsf]

AMD: microsoft! wth? why do you suck with our cpus?
MS: we were looking for your corporate christmas gift to us and couldn't find it. intel's was very generous...just sayin...

[coelhovinicius]

-see all this going on
-laughs in penguin
-gets called out
-keep laughing in penguin anyway.

If Linux ever becomes as easy to use as Windows, I'm there.

[robotron]

I wonder if they do this with AMD GPUs too. My old RX590 runs games it shouldn’t now that I’m using Linux.
