With all the perf/clk improvements RDNA2 has (+21%
), plus that ridiculous frequency (~2850MHz gfx clk) the 6700XT should probably be at ~2080Ti/3070 level at 1080p, but probably not quite make it at 1440p. Still closer to them than the 2080S I guess.
It all comes down to how much IC AMD is going to use on Navi22. AMD themselves provided the cache hit rates for 128, 96, 64, 48, 32MB etc of cache in one of their slides. 96MB should make for a quite solid 1440p card, 64MB would be a bit limited, maybe, for that resolution considering there's a 192 bit bus behind that cache.
Considering there's a few less memory controllers apart from having half the resources of Navi21 (~510mm²), I'd guess they didn't skimp on the ~30mm² it'd require to implement the extra 32MB to do 96MB. Navi10 is ~250mm², Navi22 should be around that die size after all the cutting down.
It'd be ridiculous to see a little 250mm² die mostly match up against a 754mm² x02 monster and the typical ~400mm² X04 die, lol
If they go for 96MB cache, it should be an excellent high refresh rate 1080p card that can comfortably do not quite as high refresh rate 1440p gaming.
64MB, at 1440p it'd probably behave like Navi21 does at 4k, it loses some of its punch, but it can still do its thing.
