As good as the RTX 3070 performance is, we feel that even for gaming at 1440p, that 8GB VRAM buffer is going to be less than ideal in the not so distant future. It’s perfectly acceptable on mainstream bound $300 (or cheaper) cards, but for $500, you could do a little better.
For an extra $80, there's now the option of the Radeon RX 6800 which packs twice as much VRAM. Despite costing 16% more, the Radeon is already offering gamers around 16% more performance on average. Of the 18 games we tested, there wasn't a single instance where the 3070 was faster than the 6800, which is more definitive than the
6800 XT vs. RTX 3080 comparison.
As noted in our review of the 6800 XT, Nvidia does offer an edge with Ampere GPUs in the form of more mature
ray tracing support and
DLSS 2.0, both of which you may or may not take advantage of, depending on the games you play and the small (but growing) list of titles supported.
Meanwhile, the potential advantages of the RX 6800 includes the much bigger VRAM buffer that will prove beneficial for all games that require more than 8GB of VRAM (e.g.
Doom Eternal), while SAM is a neat feature that boosts performance, though limiting the feature to Ryzen 5000 owners is not too cool.
