Smart Access Memory is a performance-boosting feature found inside AMD’s Ryzen 5000 series processors and Radeon 6000 series graphics cards. But, how does it work?
Read on to find out what Smart Access Memory is and how to enable it on your computer.
What is AMD Smart Access Memory?
AMD Smart Memory is a new feature that boosts the performance of your gaming PC when using a Ryzen 5000 processor in conjunction with a Radeon 6000 GPU.
But how does this work? Most Windows PCs only allow processors to access a limited amount of graphics memory (aka VRAM) at a time. This is usually capped around 256GB. Smart Access Memory removes those limitations by expanding the data channel to give your CPU full access to your GPU memory and improving performance.
According to AMD’s website, the feature allows for an up to 16% increase in performance, depending on the title and resolution you game in.
World of Warcraft: Shadowlands, for example, reportedly sees a 6% performance boost in 1440p, and an 11% increase in 4K. Assassin’s Creed Valhalla, on the other hand, sees a 15% boost in 1440p, but just 9% in 4K.
While the results vary depending on the title and resolution, Smart Access Memory nevertheless seems to offer improvements across the board, or at least in all the titles highlighted in AMD’s video.
