Nvidia just crushed the competition with their recent reveal of the full specs of the 30xx series...
Specs: Up to 80 CU / 5120 GPU cores
Nvidia CUDA CoresBoost Clock Speed (GHz)MemoryGraphics
RTX 3090 - 10,496 CORES - 1.70Ghz - 24GB GDDR6X350 ($1500)
RTX 3080 - 8704 Cores - 1.7Ghz - 110GB GDDR6X320 ($699)
RTX 3070 5888 Cores - 1.73Ghz - 8GB GDDR6220 - THIS IS A $499 CARD!!!
That said, Big Navi is supposed to drop at $550, and feature 16GB of (likely slower) RAM, but I still think that Nvidia won the bang for the buck war here, by a long shot. I'm not sure those extra 8GB are going to be worth the performance deficit against the 3070, and it definitely doesn't stack up to the higher end cards.
