Recently, AMD motherboard vendors are implementing a new feature that aims to optimize the Ryzen processors for best gaming performance – this was first discovered with GIGABYTE’s “X3D Turbo Mode”, and is then followed by ASUS and MSI, with the former labeling the feature as “Turbo Game Mode”.
AMD Ryzen Gains More Gaming Performance
ComputerBase (via Tom’s Hardware) recently discovered that ASUS’s new Crosshair X870E Hero now feature the new Turbo Game Mode option under the Extreme Tweaker menu in the BIOS, and enabling that option will disable SMT (simultaneous multi-threading) and one of the CCDs to minimize latency as much as possible, something that is vital for gaming performance. However, you won’t be missing out if you are existing 600 series motherboard owners – even A620 models will be getting this update as well.
This is part of the AGESA 1.2.0.2a firmware that applies to all the AMD motherboards, though it’ll take some time for each vendor to implement the update for each and every Socket AM5 motherboard out there. According to GIGABYTE, its implementation can boost gaming performance by as much as 35% for Ryzen 7000X3D, 9000X3D, and 9000 series models.
MSI is also implementing the feature and will backport it to existing 600 series motherboards, but the company hasn’t announce what name will be used to refer the feature in the BIOS. “This BIOS will still be compatible with any existing MSI’s X670(E) and B650 motherboards,” the company stated in its announcement.
Pokdepinion: Still more tricks available up its sleeve, isn’t it?
What’s the catch? Will it slow down other apps or Windows? (since SMT will be disabled).
This mode is designed for gaming – for any other use cases, it’s preferred to turn off this option since as you said, it will turn off SMT (plus secondary CCD) to minimize latency.
