So AMD Big Navi has finally been revealed. And it's pretty much a trio of high-end graphics cards.
There's a brace of graphics cards to do battle with the Nvidia GeForce RTX 3080 and the Radeon RX 6900 XT to do battle with the GeForce RTX 3090. Here are the highlights:
Radeon RX 6900 XT: This $999 graphics card will be a 4K gaming monster designed to undercut yet almost outperforms the RTX 3090. Just bear in mind that the RTX 3090 is mostly a pro and high-ned enthusiast card, whereas the RTX 3080 is Nvidia's main 4K GPU. The Radeon powerhouse goes on sale December 8.
Radeon RX 6800 XT: Think of this as the main Big Navi GPU. It has been designed as a powerful 4K at 60 frames per second graphics card, for a price of $649; that undercuts the GeForce RTX 3080. It also beats the RTX 3080 in a suite of games at 1440p.
Radeon RX 6800: This is an odd card: it's less powerful than the XT version and will chase 4K performance by delivering more performance than the GeForce RTX 2080 Ti, according to AMD. But it costs $579, which is more expensive than the RTX 3070.
If RX 6800 XT is competitive with RTX 3080, wouldn't 11 percent more CUs and shader cores basically put it up against RTX 3090? The answer: Yup.

There are more caveats this time.
- Where the RX 6800 XT was apparently run in standard mode, and
- AMD ran the RX 6800 with AMD Smart Access Memory enabled,
- the RX 6900 XT testing was done with Rage Mode (overclocking) and Smart Access Memory both turned on.
That's potentially 6-13 percent more performance, and even then, it doesn't look like AMD will win in quite a few games. But it's definitely close.
