Intel’s Rocket Lake chips can handle Resizable BAR

Intel has indicated that it has been working with Nvidia and AMD for a while to support resizable BAR. The first chips that can handle this technology are the Tiger Lake H35 processors.

Resizable BAR is a technology that allows processors to access all video memory on a graphics card through a virtual tunnel. Before that, processors couldn’t access more than 256MB of video memory directly. Making all the video memory for processors accessible provides major performance improvements.

The technology was created by AMD and HP and integrated into the pcie 3.0 standard as early as April 2008, however, it was hardly used by cpu and motherboard manufacturers. Resizable BAR now seems to be getting a big revival and is being used by AMD under the name SAM for Radeon RX 6000 GPUs and Ryzen 5000 processors in combination with AMD 400 and 500 series chipsets.

Intel is now also participating and says it will embrace the technology. The company does report that it also depends on whether laptop and GPU manufacturers will support the feature. Nvidia already indicated last year that it supports the technology. The mobile RTX chips can already handle it. Desktop RTX GPUs will be supported in March by making the technology accessible through a driver update.

With Resizable BAR embraced in a big way, Intel believes that more and more game developers will take advantage of this technology and it will eventually become a standard option in games. The fact that it is also an open standard will only accelerate growth even further.
