So it does seem as though at lower resolutions, the earlier RDNA4 drivers weren’t as efficient as they could’ve been.
In a test suite of 16 games, HUB saw an improvement of ~9% at 1440p for the RX 9070 XT (with no improvement in four games) with the latest available drivers compared to the drivers available during launch reviews. The RTX 5070 Ti saw a ~2.5% improvement under the same conditions.
The difference is minor at 4K for both cards, with a 3~4% improvement for each. Seven games in the 16-game test suite did not show improvement for the RX 9070 XT in these 4K tests.
As impressive as these gains are, overall it doesn’t really change much. Overall, [the 5070 Ti and 9070 XT] should deliver a very similar gaming experience. So then, as has always been the case, it’s the price that will largely be the deciding factor.
