Smart Access Technology works just fine on Linux. It is resizeable BAR support which Linux has supported for years (AMD actually added support for this), but which is relatively new on windows. You just need a platform with enough MMIO space. On older systems this is enabled via sbios options with names like ">4GB MMIO".

Thanks, but does this mean that every platform which supports these PCIe features will get this feature enabled with a 6000 series GPU? At least I took away from the presentation that this will be limited to AMD's 5000 series of CPUs, 500-series chipsets and the 6000 series GPUs only. My Haswell-EP should support all the necessary PCIe features and broader platform support for this feature would make the GPUs more appealing to more people (if the benefits could be realized there, too).

I don't know what windows does exactly, but on Linux at least, it will work on any platform with enough MMIO space. I suspect windows would behave the same way (although I think windows has stricter requirements about BAR resizing compared to Linux so you may need a sbios update for your platform to make windows happy).
Really want to give them a try, but not sure If the software is ready or not.Last edited by zxy_thf; 28 October 2020, 06:11 PM.

If so I saw a YT video yesterday where some one had seen some code pushed referring to the Infinity cache so maybe support is on the way.

Originally posted by piotrj3 View PostThey are both 4k gaming cards without anything beyond it and at 4k diffrence between them will be small. They are both not capable of 8k due to VRAM, they both have all exactly technologies etc. At least 3090 has vram for some 8K stuff and specific features like DLSS to make it possible.
Originally posted by piotrj3 View Postthere is literally no point to buy 6900XT
Originally posted by piotrj3 View Post, when 6800XT or RTX3080 exist, you can just buy any of those some great versions with maybe water cooling or literally the best air cooling model on market, slighty OC 6800XT/RTX3080 and you are almost the same tier performance without them being loud.Last edited by tildearrow; 28 October 2020, 09:01 PM.
