Says the guy that said I needed to use latest games and drivers. Per your request I took the most recent games from a couple of reputable sites and posted the info. It all shows that the 3060Ti, on average, is upwards of 40% slower than the 3080 at 1440p.
But, since you're so hung up on the graphs from the 3090Ti review you linked and we reference the Relative performance of the 1440p from that review (
see here). You can clearly see that the 3060Ti sits about 38% slower than the 3080. If you're lost, please continue.
If you're looking at that graph and seeing the 3080 at 84% and the 3060Ti at 61% and then going: 84 - 61 = 23%, you're doing it wrong.
61 * 1.23 ≠ 84
61 * 1.23 = 75
We'll say the 3090Ti in that graph represents 100 fps (we're removing the percentage sign in hopes to remove any confusion here). Every card below it represents the difference in fps against the 3090Ti.
3090Ti = 100fps
3090 = 93fps
3080Ti = 92fps
3080 = 84fps
3070Ti = 73fps
3070 = 70fps
3060Ti = 61fps
As we can see the 3060Ti is 64% slower than the 3090Ti. This information is extrapolated by taking 100/61 = 1.639 (we'll round up to 1.64. As a percentage we drop the 1 in front of the decimal and we have 64%)
Using that same graph we can take the data of:
The 3060Ti gets 61fps
The 3080 gets 84fps
84/61 = 37.7% difference in performance.
If you were taking the 84 and the 61 and subtracting them from each other to get the % difference in overall average performance of the 3080 and 3060Ti, you're doing it wrong. I'll show you:
84 - 61 = 23 (this number is the difference in fps, not the percentage of difference. To find the percentage of difference you need to divide the numbers)
84/61 = 37.7%
If think that the 37.7% difference is still wrong, you can do the math to verify. If you think it's only 23% you can check the math to verify.
61 (fps of the 3060Ti) * 1.23 = 75
75 ≠ 84 (the fps of the 3080)
61 (fps of the 3060Ti) * 1.377 = 83.99 (round up to 84)
84 = 84
Math is fun!
