Recently HXL on Twitter shared a cryptic tweet highlighting the max clocks on an upcoming Radeon (Navi 31) GPU. The GPU can allegedly hit 4.0GHz which we think is the max boost clock, much higher than NVIDIA’s ‘leaked’ 3.0GHz. The cooling solution would be Liquid Nitrogen as sustaining such speeds for long periods of time is not possible.

The specs for AMD’s Navi 31 were leaked by angstronomics a while back.
- gfx1100 (Plum Bonito)
- Chiplet – 1x GCD + 6x MCD (0-hi or 1-hi)
- 48 WGP (96 legacy CUs, 12288 ALUs)
- 6 Shader Engines / 12 Shader Arrays
- Infinity Cache 96MB (0-hi), 192MB (1-hi)
- 384-bit GDDR6
- GCD on TSMC N5, ~308 mm²
- MCD on TSMC N6, ~37.5 mm²
Similarly, Navi 31 was also benchmarked and compared against NVIDIA’s offerings.
Trouble for NVIDIA?
Navi 21 was able to hit ~2.4GHz, so a generational leap is increasing frequencies by ~70%. That’s insane ‘if true’. However, HXL did say ‘almost’ and the new 5nm process node is an uplift of around 1.25x. So Navi 31’s actual clock speeds should be around ~3.5GHz (2.8GHz Max for Navi21 * 1.25).
Should NVIDIA be worried? Definitely, although their silicon is also clocking in at around ~3.0GHz, so the max possible could be in the 3.6–3.7GHz territory.
With such insane clock speeds, we are definitely waiting for these GPUs to launch. Lucky for us, AMD will announce their RDNA3 lineup within the upcoming weeks. Are you excited to see how far AMD’s silicon can go this year?
