AMD has just released the latest series of new Radeon RX 6800 cards. One of the new technologies is called Smart Access Memory (SAM) technology, which allows the CPU to fully access the GPU display memory without the need for data exchange via Windows mapping. Now no longer limited to a card with AU, ASUS has released Z490 Beta BIOS, so the Intel CPU can support SAM acceleration as well.

Traditional x86 PC architecture is limited by the PCIe specification and can map only 256MB of system memory to GPU memory at a time via the Base Address Register (BAR). This limitation has a severe impact on system memory and GPU memory. Efficiency in data transmission.

AMD has added a new Smart Access Memory technology to RDNA 2. When users use the new generation of AMD’s Ryzen 5000 series processors, PCIe Mapping is no longer used and the CPU can directly access the GPU memory, completely eliminating the gap between CPU and GPU. Game performance can be improved on average by about 6%, especially for games that use a lot of textures, the performance improvement will be more noticeable.

Smart Access Memory, in fact, is not a new technology, Intel has already used it on workstations and motherboards at the server level, called Resizable BAR (Base Address Register), but it has not been used in the DIY market and also requires the GPU support. .

At present, AMD 500 series motherboards are no longer limited to SAM support. AMD 400 series motherboards have also added support. ASUS has also added Re-Size BAR support to the Z490 Beta BIOS. After boot, the Intel platform can support Radeon RX. SAM function of 6800 new card.
