AMD Smart Access Memory (SAM): How to Unlock Up to 15% More FPS on Ryzen 7000 Series CPUs is a game-changing technology that allows your CPU to directly access the entire VRAM of your GPU, eliminating bottlenecks and boosting frame rates in many games.

Understanding AMD Smart Access Memory (SAM)

AMD Smart Access Memory, or SAM, represents a significant leap forward in how CPUs and GPUs communicate. Traditionally, CPUs were limited in their access to a GPU’s video memory (VRAM). SAM removes this limitation, offering the potential for increased performance in gaming and other graphically intensive tasks.

Let’s explore the technical basics of SAM and how it overcomes traditional limitations.

The Technical Foundation of SAM

SAM leverages the PCIe bus to enable resizable BAR (Base Address Register). This allows the CPU to access the entire VRAM of the GPU, rather than being restricted to smaller chunks. This expanded access unlocks several benefits.

Overcoming Traditional Bottlenecks

In traditional systems, the CPU often has to request data from the GPU in small segments, leading to delays. SAM streamlines this process, allowing the CPU to fetch larger blocks of data more efficiently, which can significantly reduce bottlenecks.

Here’s a list of benefits conferred through enabling SAM:

• Enhanced Data Throughput: Larger data transfers between CPU and GPU.
• Reduced Latency: Decreased waiting times for data requests.
• Improved Performance: Noticeable FPS gains in supported games.

In summary, AMD SAM is a clever technology that takes advantage of PCIe bus architecture to give CPUs more complete access to GPU memory. The result is reduced bottlenecks, so that the CPU can access and use memory more rapidly. The result is more efficient graphics rendering, especially in visually demanding video games.
