Resizable BAR Tested with Intel - The Power of Boosted Memory Access

WYP · #1 30-01-21, 10:55 AM

Resizable BAR is no longer an AMD-only feature. Will Intel systems receive the same performance benefits?

Pretty impressive to say the least. Almost like DLSS magic where a click of a switch and boom instant fps increase, not to the same extent but still impressive. It'll be interesting to see how much impact alongside DLSS this would have. Would it be another similar magical boost? If so Nvidia will really be hammering AMD even more.

Bring on the RTX Bios's with this feature enabled, not sure why Nvidia is taking so long, it seems the driver is already prepped.....

Driver enablement isn't supposed to be coming until the release of the RTX 3060. Nice to see that there is a way to confirm it is working on Nvidia hardware. With AMD you kinda need to trust that it's working...

Nvidia needs to do a lot of validation before it goes public. They need to make sure that enabling this does not add new bugs or degrade performance in some instances.

Yeah I heard that AMD disables Resizable BAR on driver level for many titles, since it can lead to issues.

Guess we'll have to see how it looks with Nvidia then, because if this doesn't create any negative issues, it's an absolute nobrainer.
Let's just hope that motherboard manufacturers don't lock this for the cheaper models...

I wonder if resizeable bar could implemented on PCI-E 3 systems or is PCI-E 4 a requirement ?

The Intel system that I used does not support PCIe 4.0, so that should answer your question.

PCIe 4.0 just adds more bandwidth to the interconnect, it won't give more GPU memory access.

Ahh yeah gotcha, I wonder if this could be implemented for older gen cards and not just new gen ones.

I'm sure it can be implemented for older cards with GPU Bios update, but the big Q is will vendors bother updating any bios's older than current gen cards and will Nvidia give them the tools to do so...
