A photo of an AMD Ryzen 9 9950X processor

We live in some strange times. Let’s say you’ve splashed the cash and bought yourself a brand newRyzen 9 9950Xprocessor. It’s got 16 cores, 32 threads and it’s a seriously capable CPU, though not the absolute best for gaming. Well,Asusreckons it has a fix for the latter in the form of a new Turbo Game Mode, that halves the number of cores and quarters the number of threads.

Specifically, what Turbo Game Mode (TGM) does is disable one of the CCDs (Core Complex Dies) and SMT (Simultaneous Multithreading). In short, it turns the likes of the 9950X into an 8-core, 8-thread processor. The idea is that some games just don’t like to have threads scattered across separate dies or sharing any cores.

A screenshot of an Asus motherboard BIOS, showing the Turbo Game Mode option

To see if this is the case for any of the games in our CPU benchmarking suite, I ran them afresh with thebeta 2505 BIOSfor theAsus ROG Crosshair X670E Heromotherboard. The test setup used aRyzen9 9950X, 32 GB of DDR5-6000 CL28, aGeForce RTX 4070, and Windows 23H2.

You can see the results for yourself below but as a quick summary, Cyberpunk 2077 and Baldur’s Gate 3 ran worse with TGM enabled, Metro Exodus and Total War: Warhammer 3 ran exactly the same as without it, and Homeworld 3 and Factorio ran better with it on.

A mixed bag but when Homeworld 3 only ran 2% better on average, and Factorio 5% quicker, it raises a simple question: Is it worth using it at all?

One thing worth considering is that this is a BIOS option and not something that you can flick on and off while in Windows. TGM absolutely ruins the CPU’s content creation capabilities so it’s not a setting that you’d ever use in that situation.

And unless you only play a specific collection of games, where TGM does help, you’d get pretty annoyed having to reboot your PC every time you wanted to play something different.

The biggest gaming news, reviews and hardware deals

When I first reviewed AMD’s dual CCD Zen 5 chips, theRyzen 9 9900Xand 9950X, I noticed that the recommended power settings actually made things worse. AMD stated that one should use the Balanced power profile in the old Control Panel and then Balanced or Best Performance in Windows settings.

This configuration would allow AMD’s drivers to activate core parking on the second CCD when a game is detected. In other words, turn the 9950X into an 8-core, 16-thread chip from the perspective of the game. I found that this didn’t actually help and the review performance figures were collected using High Performance in the Control Panel (i.e. no core parking).

Mindful of the fact that there have been numerous updates to AMD’s drivers, Windows, and AM5 motherboard BIOS files since then, I went back to see if the recommended power profile settings were better.

Well, they’re not, or at the very least, they’re not with my configuration—High Performance/Best Performance still produces better results than Balanced/Best Performance, although the gap between them is now a lot smaller than it was originally.

Now, I’ve only tested five games, which is a tiny sample, and I’m sure there are games out there that would genuinely benefit from Turbo Game Mode being enabled. However, having to jump in and out of the BIOS to switch it is a drag and I can’t see many opting to use it regularly if the overall change it brings is zero.
