The AMD Big Navi, possibly a Radeon RX 6900 XT, could destroy the Nvidia GeForce RTX 3080 in GPU clock speed and beat it in overall performance.

Reliable leaker Patrick Schur tweeted a series of specs for the Navi 21 XT, aka Big Navi, stating that the graphics card will feature 16GB of GDDR6 video memory and a 2.4GHz "Game Clock." This appears to be the GPU's clock speed when running games, not the base or maximum clock speed.

Comparatively, the GeForce RTX 3080 has 10 GB of faster GDDR6 VRAM, but is clocked at only 1.71 GHz. Depending on the interaction between clock speed, memory speed, and bandwidth, the Radeon RZ 6900 XT may have room to beat the mighty $699 Nvidia graphics card.

The 2.4GHz clock speed is also the fastest speed a consumer-grade graphics card has ever reached, meaning AMD could set a new benchmark in this case. Speaking of benchmarks, the benchmark we have seen so far has Big Navi nipping at the heels of the RTX 3080.

However, the Radeon RX 6000 series, which will be unveiled on October 28, will consist of multiple graphics cards. This means that the benchmarks leaked so far may not be from Big Navi, which AMD sees as the most powerful next-generation GPU it can introduce in the graphics card field.

Big Navi, and other Radeon RX 6000 graphics cards, will use the new RDNA 2 GPU architecture, which is also found in the PS5 and Xbox Series X. This suggests that the upcoming Radeon graphics cards will support ray tracing, but it is not yet clear if they will have dedicated hardware like Nvidia's latest GeForce RTX 3000 series.

All will likely be revealed at AMD Radeon's big showcase next week. We expect to see a powerful set of graphics cards that can challenge Nvidia's latest high-end GPUs, but could also undercut Nvidia in terms of price, which would bring some serious competition to the market.
