Here we re-run four benchmarks with the RX 6600 XT, but this time with Resizable BAR enabled. According to AMD, a Ryzen 3000/5000 CPU is required to use Smart Access Memory (SAM), as is a 500-series motherboard. However, my ASUS ROG Maximus XII Hero offers support for Resizable BAR on the Z490 platform, so I put it to the test with the RX 6600 XT. We have tested this previously and the gains aren't as big as we would see if we were using a Ryzen 3000/5000 CPU and compatible motherboard, but we can at least highlight the potential performance that is on offer for those with other systems.

There's no real surprises here, with the RX 6600 XT up to 8% faster with Resizable BAR enabled when looking at Assassin's Creed Valhalla, though the gains are smaller in Cyberpunk and Resident Evil Village. Watch Dogs: Legion even shows a tiny regression, though the difference of just 0.3FPS is clearly within our margin for error.
