Nvidia reveals Resizable BAR support for Geforce RTX 30 series products

Nvidia has confirmed that Resizable BAR support is coming to their RTX 30 series graphics cards, allowing Nvidia's latest graphics cards to utilise the optional PCIe function to enable increased performance within many gaming applications. 

Resizable BAR support allows CPUs to access the entirety of a graphics card's frame buffer, allowing more data transfers to happen concurrently and increase the performance of a variety of PC titles. AMD calls their implementation of this feature "Smart Access Memory", and Nvidia's fast implementation of Resizable BAR within their graphics cards should show you how impactful this feature can be. 

Nvidia plans to deliver Resizable BAR support to their drivers in February alongside their RTX 3060 graphics card. This feature will also be part of Nvidia's RTX 30 series mobile GPUs and all future Geforce graphics cards. 

For existing RTX 30 series owners, enabling Resizable BAR isn't just a driver update away. Users of existing RTX 30 series graphics cards will need to update the VBIOS of their graphics cards to enable support for this new feature. This feature will also require motherboards to support PCIe's Resizable BAR function. 

Nvidia has confirmed that they have been working with Intel, AMD and motherboard manufacturers like ASUS, ASRock, EVGA, Gigabyte, and MSI to enable ReSizable BAR support across a wide range of motherboards.

Dude it's in the article... It's coming for everyone. 3060 is just launching alongside it with the correct BIOS. Other cards will need a bios update.Quote

The article mentions AIB cards, not the FE's.Quote

As resizeable bar is part of the PCI-E spec I wonder if this could technically work with PCI-E 3 ?Quote

FE edition owners will get BIOS updates. Nvidia would be fools not to do that.

Yes, it is in the article. I think he is mixing taking the motherboard manufacturers statement out of contents. Remember, resizable BAR needs support from motherboards and graphics card.

" Users of existing RTX 30 series graphics cards will need to update the VBIOS of their graphics cards to enable support for this new feature." That refers to all GPUs, not just FE cards.

"Nvidia has confirmed that they have been working with Intel, AMD and motherboard manufacturers like ASUS, ASRock, EVGA, Gigabyte, and MSI to enable ReSizable BAR support across a wide range of motherboards."

That statement mentions specific brands, but in the context of them being motherboard manufacturers.Quote
