AMD's Ryzen 9000 series are slightly faster on Windows admin accounts – and no one knows why

WTF?! AMD pulled the wraps off their latest Ryzen 9000 desktop processors powered by the new Zen 5 architecture this month. But there's an odd catch – the chips seem to deliver better gaming performance if you're logged into a full Windows administrator account.

The quirky discovery was made by our own Steve Walton at Hardware Unboxed while benchmarking the Ryzen 7 9700X. After putting over a dozen games to the test, he found the 9700X was averaging around 3.8% higher frame rates when using a Windows administrator login versus a standard user account.

And it's not just these latest chips – the previous-gen Zen 4 chips (Ryzen 7 7700X in testing) exhibited a 2.8% boost as well...

The performance also fluctuates wildly between games. Steve saw a 7% improvement in the average frame rate in Cyberpunk 2077. That may not sound like a lot, but it translates to 10 FPS, which is no joke.

Curiously, this performance delta only crops up in games. Application benchmarks like Photoshop, Premiere, and Blender all performed identically regardless of the account privileges used. AMD has corroborated Steve's findings and confirmed that maximum performance can be indeed extracted from an admin login (or running games "as administrator" was found to work as well).

This is obviously not an ideal long-term solution given the security implications of routinely using an administrator-level account. Admin users have elevated system privileges that could be exploited by malware or hijacked through tactics like phishing. The best practice is to use a regular user account for everyday computing to minimize risk.

Regardless, Steve tells us there was a lot of back and forth between him and AMD to find the source of the performance discrepancy before a possible cause was worked out. In a nutshell, it seems there's some kind of performance bug in Windows 11 that's hampering Ryzen processor capabilities in gaming workloads when running under a limited user account.

Steve also stresses that it's a general Ryzen bug and not something specifically impacting the latest Zen 5 chips, so this is no reason to skip them. It isn't yet clear if Intel chips are affected – that will probably need some more testing.

The positive news is that AMD says the bug should be resolved in a future Windows update, so the best course of action for now would be to simply…wait. But for hardcore gamers looking to eke out every last ounce of power from their new (or old) Ryzen CPU, creating a secondary admin profile could be a worthwhile stopgap – just don't take our word for it.

So if it affects all Ryzen CPUs, why did it take Steve to figure this out?!?

And why can it only be fixed on the Windows end?

How has AMD fabricated a CPU architecture (actually several) that gets limited in this way?

And not notice for YEARS?!?

Run Linux and you won't be limited in this way? It's clearly a Windows / Microsoft bug and if you want to be a conspiracy theorist then it's probably because Intel was paying off MS to limit / hamper AMD CPUs. As to why no one would notice...because no one would / should run games via an "admin" account and it's probably not a scenario that gets routinely tested and even then..would most likely be written off as a "Windows bug" anyway.
 
Are we sure about that attribution to Steve? Rumblings about this came days earlier from Level1techs' Wendel in musings about discrepancies windows vs linux peformance.

I expect Steve was the first to test it extensively, but I don't know that it would have occurred natively because he never tested that way to begin with and so wouldn't have had a frame of reference to say it's definitely something in Windows.

Plenty of people run windows in admin mode… and regardless of whether the issue is Windows’ or AMD’s, it is on AMD to solve it - as people will buy windows anyways (got to love a monopoly), but can switch to Intel if they have problems…
 
What namby-pambiness is this? Admin-mode only presents risk if you are objectively not intelligent enough to even know how to switch to admin mode and yet somehow accidentally(!) turn it on, in which case you won't be aware of your admin status, have never heard of antivirus software, and so will obviously click on sketchy links in emails about how your car's extended warranty has expired.

A person who knows what admin mode is (it's rather self-evident) will also know enough not to click on obvious phishing links, and will know to install a broad-range anti-virus/threat mitigation application.

I've run admin mode exclusively on every Windows PC I've owned. I have that idiocy of UAC turned off. My PC's have never been compromised, going back to Windows XP.

This falls into the warning labels on buckets that if you stick your head in it while full you could drown.

It is not just an account with admin privileges but the actual hidden admin account so I doubt many people do run as this admin account. I speculated the performance delta was a windows issue back in the 9700X launch comments and it will be for AMD and Microsoft to solve. Switch to intel if they wish but how long will their 13th and 14th gen intel chip last?
 
I dont think is a Ryzen issue, I have noticed this a long ago, there are certain silent actions at app level that are denied by security and that game of asking and getting denied makes a bit of a bog on limited users.

No... it's just any account with admin privileges... it also works by simply right-clicking a game and "running as admin"..

It's definitely a "Windows Issue" but... it's on AMD to fix this - or at least bring it to someone at MS' attention... and since it's been around for YEARS - why hasn't it been addressed yet?
 
Does it only apply to games with anti-cheat software? I would imagine the anti-cheat software would have to job through a lot of additional hoops if it wasn’t running as an elevated account. Otherwise, I have no clue what may cause this.
 
Is this a dual ccd issue or are the single ccd chips affected too? How far back are ryzens affected? Is my 5800X affected?
