AMD has introduced Variable Graphics Memory (VGM), a feature that allows users to dynamically allocate up to 75% of their system memory as dedicated video RAM. This is achieved by tapping a button in AMD’s desktop Adrenalin app, making it easy to reroute power without diving into the BIOS.
Currently available for AMD AI “Strix Point” laptops, VGM can turn a 32GB laptop with 512MB of video memory into a 24GB one with 8GB of dedicated VRAM. The amount of RAM that can be diverted depends on the system’s total RAM.
In early testing, turning on VGM didn’t prove to be a silver bullet for every game. While some titles saw significant frame rate boosts, others experienced smaller or no boosts at all. For example, playing Control with 8GB of VRAM resulted in a notable 11-frame-per-second (fps) increase from 54fps to 65fps.
AMD also announced the Fluid Motion Frames 2 (AFMF2) technology, which is now available for Strix Point laptops in technical preview. AFMF2 increases frame rates by imagining new frames, reducing jitter and lag. When combined with VGM, assuming a baseline of at least 50fps, users can expect substantial boosts.
The company also unveiled the RX 7800M, a new up-to-180W chip featuring 12GB of dedicated video memory. This GPU is essentially a stripped-down version of the RX 7800 XT and fills a gap in AMD’s lineup between the flagship RX 7900M and the RX 7600M XT.
