Did you see any single WU times for the 3080?
Did you see any single WU times for the 3080?
I saw this in the comments:
AP27:
2080: 660-720
3080: 290
PPS Sieve: (2 tasks simultaneous)
2080: 215
3080: 170
As usual, avoid anything requiring FP64 with these GPUs. An old AMD 7970 is still over twice as fast as even a 3090
Saw that too. I want to see how it compares to 2080 Ti
Many of them that didn't do so well in the silicon lottery are crashing, artifacting, freezing up, blackscreening, etc. Because of that, GPU makers will start issuing new BIOS versions that downclock the GPUs so they'll work properly. Of course this means crunching perf will also drop. Not sure yet by how much.

Why didn't they wait until they had it dialed in to release it since AMD doesn't have their new GPUs out yet? Did they just get too greedy?
Anyone remember the Intel 5775C and how you could leverage the 128MB of L4 cache it had for performance gains? AMD has been rumored for months to be doing something similar for their GPUs coming out this month, but never found much evidence to support it. Now there's more evidence, though still a rumor. Seems AMD filed for a trademark of this technology and officially called it Infinity Cache so it's definitely real now, but it doesn't prove it will be in this next gen of GPUs. Keep your fingers crossed.
Rumor is Nvidia scrapped the 20GB 3080 and the 16GB 3070 and 3070 Ti today. They most certainly were real, as they were appearing in BIOS data and various PSU support lists. No official reason why was given.
I hope it's not a bad sign, meaning they found out what Big Navi can do and they aren't worried about competition so they dropped the larger memory SKUs. I really hope it's something else...
What do you make of the RTX 3090 listed slower than a RTX 2080Ti on PPS Sieve?
