Eh, I remember enough of us being skeptical but either way, this isn't two years ago. But if you're playing current or older games the ram won't matter. Then again, if it doesn't matter that much why not buy one of the older cheaper 8GB cards that are two years old now? Frame generation I guess.
Few complained because no one could actually buy them. By the time the 3070 actually launched it was full ETH & Covid. 8 GB was fine for mining. The size of the frame buffer when it related to gaming was largely academic.
But I've been skeptical of them being 8GB the whole time. If they had been for gamers and not miners, there would have been more feedback IMO, but we'll never know.
The 3070ti, which launched later was the one I was most critical off because... it launched later. I don't give a darn about it having GDDRX, as I've already said. It could have gotten a solid 20% more bandwidth just using higher tier GDDR6 AND had 16GB too. But no.
