For anyone heavily invested in ray tracing, sticking with Nvidia-who brought it to market a generation sooner-might be the better bet if you can't wait a few months to see how those features and their performance shake out in the market. If all you're looking for is the best raw 4K frame rates on current AAA games, ray tracing be damned, the top end of the RX 6000 series seem like clear winners. Both of these AMD cards sport 16GB of GDDR6 VRAM, as well, but that's not clocked as highly as Nvidia's choice of GDDR6X VRAM (11GB of it in the RTX 3080, and 24GB in the RTX 3090). That's where Nvidia's RTX 3090 costs a whopping 50 percent more than AMD's RX 6900 XT for roughly the same 4K frame rates delivered. The value proposition is closer to even when upgrading to the 6800XT and just about overwhelming at the top tier. The RX 6800's 16GB of GDDR6 VRAM doubles that of Nvidia's comparable RTX 3070. But in other ways, AMD might have the edge-if higher amounts of VRAM in each class are your selling point. Consumers will probably have a hard time justifying an extra $80 at that price bracket on a card with higher thermals and a more uncertain real-time ray-tracing pedigree. In some ways, AMD looks like it might have gotten caught with its pants down on the RX 6800 pricing. On the lower end of the lineup, Nvidia takes the lead, with the 220W Nvidia RTX 3070 beating the 250W Radeon RX 6800. The new RDNA2 architecture also brings greater power efficiency to the Radeon lineup, with the 300W 6800 XT and 6900 XT beating out their Nvidia competitors by 20W and 50W, respectively.
