As expected, SAM will be an integral part of AMD’s increased performance and now NVIDIA is unveiling the technology by claiming that BAR is part of PCI Express specifications. While there was no confirmation of this, there were many rumors about it, with the company stating that its Hardware supports it and that it will be powered on its Ampere GPUs.
If Ampere supports intelligent memory access, why is it not already enabled?
The most obvious and perhaps the most important question. The fact is that, obviously, NVIDIA has not seen the need to do the job with technology so far, when its rival has already introduced flying instruments that way.
So, once in the ring it looks like the two will once again compete with this and it is likely that AMD’s profits will be put in place if NVIDIA keeps track of the distance and with the same performance jump as AMD.
The company has announced that the support will be for Ampere GPUs in the RTX 3000 series and will come as software updates (possibly for drivers) with something new that will separate them from AMD and set the trend: it will be fully compatible with programs based on Intel and AMD CPUs.
This could cause AMD to open its hand to try to disrupt its technology with Intel, as there is nothing at first that makes us think it should be its only platform.
Both AMD SAM and the same NVIDIA will also be drinking
The fact is that although the announcement of AMD is on the table as today it is NVIDIA, the technology will come later than when the GPUs are still around. In addition, AMD seems to indicate that PCIe 4.0 is required to support SAM, but in reality and if we are accurate, the BAR is involved in what it says and should be compatible with PCIe 3.0
This is due to the 256 MB allocation we talked about yesterday and how this new technology will allow full access to GPU memory, eliminating any potential occasional problem, resolutions and Hz.
From NVIDIA, re: SAM: “The power of BAR resilience is part of the PCI Express spec. NVIDIA computer hardware supports this functionality and will enable you to Ampere GPUs with upcoming software updates. We have an internal function and we see the same performance results. “

From NVIDIA, re:SAM: “The capability for resizable BAR is part of the PCI Express spec. NVIDIA hardware supports this functionality and will enable it on Ampere GPUs through future software updates. We have it working internally and are seeing similar performance results."

As we have seen with AMD, the benefits can range from 5% to 11% in performance, which is more than worth considering the increase in performance of GPUs from one generation to the next.
So it is more than expected that NVIDIA statistics are the same and above all, as it affects the Intel and AMD platforms, as this can set the balance for card purchases in some way.
