AMD Big Navi leak reveals big boost speeds to fight Nvidia RTX 3080

Another leak for AMD's upcoming Radeon RX 6000 serial, which includes the Big Navi graphics cards, has popped upwards in Apple'south macOS BigSur 11 beta. And by the looks of things, AMD'south new cards could boast promising performance to claiming the Nvidia GeForce RTX 3080.

A Reddit user posted some specs for both Big Navi (aka Navi 21) and Navi 22, a less powerful GPU going by the codename of Navy Flounder. The specs have a lot of data that was leaked in a recent Linux update, but this time reveals some tidbits well-nigh clock speeds.

The latest leaks take Large Navi tipped to come with 80 compute units (CUs) and 5,120 stream processors, and the new leak notes ane version of Big Navi will ramp up to a clock speed of 2.2GHz. Comparatively, the standard edition GeForce RTX 3080 boosts upwardly to i.71GHz.

And our sister site Tom's Hardware noted that Navi 21 could evangelize unmarried-precision operation of 22.5 Tflops. That's an impressive figure but information technology falls short of the GeForce RTX 3080's 29.viii Tflops, which ways that Big Navi might not be the "Nvidia-killer" information technology has been previously championed as.

Interestingly, Navi 22 is tipped to achieve a clock speed of 2.5Ghz. Just it will supposedly have 2,560 stream processors and 40 CUs. All that ways information technology is tipped to deliver 12.8 Tflops of performance.

Both graphics cards await prepare to offering a strong upgrade over the Radeon RX 5700 XT and RX 5700, which are based on the older RDNA compages. The Radeon RX 6000 series volition use AMD'due south RDNA 2 architecture, which the PS5 and Xbox Serial 10 GPUs are likewise using.

Reference was also made to Navi 31, which Tom's Hardware noted could come with the same stream processors and CUs as Large Navi but potentially have a higher clock speed and increased functioning. But most notably information technology will apparently accept AMD's RDNA 3 GPU architecture, potentially making it a future refresh of Large Navi.

It's worth pointing out that Mac machines tend to utilise Radeon Pro graphics cards, and then the clock speeds and teraflops performance might not be correct for consumer variants that can exist popped into gaming PCs.

The Radeon RX 6000 series is expected to be revealed on Oct 28. So we haven't got as well long to look to encounter what AMD has in store for its side by side-generation graphics cards.
