The 4070 is basically a more efficient 3080 with extra features for $600. It's a decent value in the 4000 lineup, but not amazing. About 22% slower than the 4070 Ti, and 25% cheaper. The 6950XT for $610 is about 5% to 20% faster in games, and has equal RT performance, but no DLSS 3. I ended up getting a 4070 Ti about a month ago. I mighty have gotten this instead if it was available. The 4000 series has about the same performance as the 3000. The 3000 series could support DLSS 3, but it wont because then there'd be almost no reason to get a 4000. The only reason Nvidia needed to switch the new Samsung node process was to improve power efficiency enough to make a 4090 and 4090 Ti.
