Intel promises to add Smart Access Memory support to Arc Alchemist graphics cards

Intel has confirmed that Arc Alchemist discrete graphics cards will eventually receive support for Smart Access Memory, which opens up the AMD Ryzen CPU to the entire RAM stack of the graphics card.
Thanks to this, performance in some games can significantly increase.Image source: IntelIntel previously reported system requirements for Arc Alchemist graphics cards, which indicated the need for support for Resizable BAR (ReBAR) technology in the computer.
The feature must be active for \"optimal\" performance of Intel discrete graphics cards.
The counterpart of Resizable BAR is Smart Access Memory (SAM) technology.
It is used on AMD platforms.
Talking to Neowin, Intel representatives confirmed that Arc will also support SAM: \"As we noted in our blog post, the deployment of Arc series graphics products involves a phased and gradual rollout to target platforms to better serve our customers.
Our platforms support Resizable BAR technology and in the future, when Arc graphics cards become available at retail, we will add support for AMD platforms with their Smart Access Memory,\" Intel commented.As with Intel platforms, of which not all support or fully support Resizable BAR, not all AMD platforms support SAM.
This feature requires a Ryzen 3000-series processor no older than Ryzen 3000 (Ryzen 3000G models are not supported) and a motherboard with an AMD 500-series chipset.
The future Socket AM5 platform for Ryzen 7000 processors is also likely to get SAM support.According to Neowin, the first gaming tests show that the Intel Arc A380 desktop graphics card on a PC with AMD processor perform worse than on a PC with Intel.
It is very likely just because the latter lack support for Smart Access Memory technology.
