The new design is awesome (if true), I get the mixed feelings though as it is different, but I personally feel the curved V-heatsink and fan on either side is awesome. I'm sure there will be some lighting too which could further improve the look in an actual system, I just hope NVIDIA implemented fan-stop option this time.
Wow, if true Nvidia ain't joking this time. 3080 could be based off the big die, GA102. I hope AMD is prepared for that.
Nvidia hasn't done this since the 700-series.
The Series X manages to fit 56 CU + 8 Renoir Zen 2 cores in 360mm2. Assume you take about 40mm2 for the CPU cores plus 20mm2 for I/O, Cache, SRAM etc. That leaves around 300mm2 for the GPU component.
So 56CU of RDNA 2 takes up roughly 300mm2.
There are 3 known RDNA2 dies:
Navi 21 = 505mm2
Navi 22 = 340mm2
Navi 23 = 241mm2
Quick maths:
Navi 21 = 56cu/300mm2 x 505mm2 = 94.26 CU
Navi 22 = 56cu/300mm2 x 340mm2 = 63.46 CU
Navi 23 = 56cu/300mm2 x 241mm2 = 44.98 CU
Bare in mind my quick maths doesn't account for the die space memory controllers, I/O, etc. take up.
So, based on that theoretically:
Navi 21 = 96CU (6144 stream processors)
Navi 22 = 64CU (4096 sp)
Navi 23 = 44CU (2816 sp)
Take this with a pinch of salt as always. But I think its reasonably well understood that Big Navi (Navi 21) will be at least 80CU (5120sp).
I think AMD will actually try to compete, but lets wait and see what happens.
