Intel was right: in this case, it is better to buy GeForce or Radeon. Lack of support for Resizable BAR has a huge impact on the performance of Arc maps

As shown yesterday’s reviews, the Intel Arc A770 and A750 video cards turned out to be quite good in terms of their capabilities at the recommended prices. But still, the cards have disadvantages, and one of them has been tested in practice.

We are talking about Resizable BAR technology, which greatly affects the performance of Intel adapters.

As recent tests have shown, with the Resizable BAR turned off, the performance of the Arc A770 drops by about 20-25%, depending on the resolution. This is quite a lot, so buying an adapter for a system without support for this technology is not very advisable. In fact, even Intel itself recently said directly that owners of older platforms without Resizable BAR support would be better off buying an Nvidia or AMD video card.

Recall that Intel updated recommended PC requirements to install Arc maps, and they are just tied to Resizable BAR support. AMD calls this technology SAM.
