After amd released the sharp dragon 5000 series processor and Rx 6000 Series graphics card, it proposed a technology called Sam intelligent access, which can let the processor access all the video memory of the graphics card, which is claimed to improve the game performance by up to 13%.
Amd initially proposed 500 Series motherboard as the platform requirement, but then it was opened to 400 series motherboard. Manufacturers have begun to update BIOS one after another.
At first, I thought this was the unique secret of AMD 3A platform, but soon, NVIDIA said that it just borrowed the standard technology of PCIe, and their graphics card can also be used.
Motherboard manufacturers have proved with practical actions that Intel platform also supports it. Intel 400 series motherboard and Rx 6000 Series graphics card have been successfully opened.
It is found that AMD SAM technology is not mysterious, it is not a platform patent, but based on a special feature in PCIe standards
A new physical layer named "root complex" has been added to the core root complex of the Reebok 5000 series processorfull-rate_ pdep_ u32/64It is through it that Sam acceleration technology can be realized.
But unfortunately,This change was added Zen3 the architecture, none of the previous Zen2、Zen 、Zen structures were available, that is to say, the Ruilong 3000/2000/1000 series is completely impossible to support SAM..3
But the interesting thing is,Intel's fourth generation core Haswell, released in 2014, already supports reconfigurable bar, and the corresponding motherboard is 8 series.
In other words, as long as the motherboard manufacturer is willing to provide BIOS,Intel platform for these six years, can achieve SAM acceleration function!
Of course, the old platform a few years ago can't be updated, but at least 400 series motherboards with 10 generation core, 300 series motherboards with 8-generation / 9 generation core are all OK, it depends on the motherboard manufacturer.
As long as your motherboard BIOS has these two options, you can turn on Sam
