Nvidia had announced that the RTX 3060 was going to have support for Resizable BAR technology, which allows the CPU to access the GPU's VRAM more efficiently, obtaining a small performance gain. However, this will not be the only GPU that will use it, so will the RTX A6000.
Resizable BAR technology is part of the PCI Express specification but has not been enabled until now. To activate it, compatible hardware is required, in addition to a modification in the BIOS of the graphics card.
So far, the only Nvidia RTX 30 series graphics card that supports Resizable BAR is the RTX 3060, but the green team is extending its support to RTX A6000 workstation graphics cards.
NVIDIA is promising to release the supported BIOS for its RTX 30 Founders Edition cards during the month of March, as well AIB partners for their custom models.
The discovery of the Resizable BAR technology present in the RTX A6000 comes from Reddit, where the user 'millenia3d' published a screenshot that confirms it.
The Nvidia RTX A6000 graphics card is the only graphics card that takes full advantage of the GA102 silicon, which contains about 10,752 CUDA cores. The 48GB memory capacity is doubling that found in an RTX 3090, although the memory type is GDDR6 and not GDDR6X.
Buying the Nvidia RTX A6000 is costing about $ 4,650, a far higher price than the RTX 3090.
