if the 6800xt does 100mh and 180 watts it will be a great miner.
if the 6800xt does 90mh and 200 watts it is okay.
It also needs to be available.
I almost got a Nvidia 3080 at Best Buy today. but it locked out of the cart,
Why does everyone assume these ridiculous numbers for 6000 series GPUs? Did you see the specs? They all have GDDR6 with 256 bit bus, 512 GB/s bandwidth only. They will do ~60 MH/s at best in stock, maybe up to 70 MH/s with memory overclock.
If it was entirely VRAM based then an ASIC would simple need HBM and a cheap FPGA or CPU to mine beyond that capable by a video card. The cores have to actually calculate the solutions and the RAM is needed to index that table. Clearly the core count is significantly higher because they were able to increase the efficiency even on the same node, so more of that 16GB of memory will be utilized. You could pair a RX460 with HBM memory and map a large bus to the memory it would still crawl. You need all parts running for ETH (even though everybody always parrots that core is irrelevant).
