The high clocks look really impressive but we've seen it all before - people already hit 3000mhz on Turing cards last year. The performance gained is more important anyway and the high clocks don't translate into that much more performance for whatever reason - comparing a 6800xt at 2.2ghz and one at 2.8ghz, the latter is just 10% faster in games despite having 25% higher clocks
3GHz on Turing? Exotic cooling perhaps, but definitely not on air. Here people are already hitting limits hard-set by AMD (2.8GHz) and likely soon 3GHz. On air. And the only limit so far, is said BIOS hard-limit, not actual chip's limitations.
