They clearly said the 3080 is around 80% the performance of the 2080 in like 5 diferent games. How on earth did you go on to say that its then going to be twice the performance of the 2080ti? Nvedia claimed 2x the performance, digital foundry said 1.8x the performance. This is why I say the 3070 wont be as powerful as a 2080ti. Yes nvedia flops have always been better, wich is why I tried to correlate performance between nvideas cards and you brought up amd. But if you compare tflop to tflop from touring to ampere, performance is lost and its what I was arguing from the very begining. Yes, I saw I was wrong about the price, then I edited and corrected it. But you where wrong also as you claimed it was $500 and are trying to pretend you always said $450. And at the same time not addressing that the $450 dollar 5700xt beat in performance the $500 rtx 2070, not only that it got pretty close to the $700 rtx 2080. I would say for not having hardware based ray tracing, that is very good. And no, digital foundry did not backed what nvidea said, they where 20% below and I would argue thats a very big gap to be discarded as marging of error. There is no real info on the 3070 real world performance. We have digital foundry comparing the 3080 to the 2080. From there I just calculated from the paper specs. on paper, the 3080 is 33.33% better than a 3070. the comparison digital foundry made demonstrated the 3080 is around 80% better than a 2080. I know its not how it should be done, but we have no other data, but I did a quick rule of 3 to asses the 3070 is 20% better than a 2080. But the problem is that the 2080ti is at least 30% better than a 2080. thats why Im giving it a marging of error and say that they will at most match the 2080ti. |
I did read the slides and watch the video that's how I know that nothing really backs anything you've try to say because the were times in the DF video where performance jumped to like 96% the 80% is an overall average and 1.8 in 4K with raytracing and all at ultra falls into the region of twice the performance that's how such numbers work.
Your Tf part again is not making sense because what is shown is contradicting you if performance is lost how are games running much better with what you claim is a smaller jump? How is it DF are saying the news cards are allowing things to be done while running 4K with raytracing and 60fps? That indicates quite the opposite of what you're arguing and yes AMD would be brought up because you're using this argument to make their case.
5700xt doesn't beat the 2070 the latter is slightly better at the same performance and the former isn't close to the 2080Ti where did you even get that from the 2080Ti is 35% better than the 5700xt and that's with out features like raytracing, even the 2080 is 18% better in performance and the 2080 Super which replaced the 2080 is 25% better. These numbers are from benchmark where

The last part I don't even know who taught you math or what kind of math you're trying to apply because your own logic contradicts you in this part because you say that on paper 3080 is 30% better and gets 80% better performance which not only contradicts your earlier notion on less performance per flop but you go on to say that 3070 being 20% better will only match the 2080Ti in real performance after calculating 30% lead to 80% increase performance on the 3080? Under your own math 20% better specs on the standard 2080 would be roughly around 50-60% increase in performance, the 2080Ti has a 15% increase over the standard 2080 this means under your own math the 3070 would surpass the 2080Ti as they've said.
