You have a very interesting relationship with the truth.
Rough estimates from Techpowerup's reviews:
GTX 1060 => RTX 2060: +~63%(1440p) +~60%(1080p)
GTX 1070 => RTX 2070: +~44%(4K) +~41%(1440p)
GTX 1080 => RTX 2080: +~43%(4K) +~41%(1440p)
GTX 1080 Ti => RTX 2080 Ti: +~38%(4K) +~33%(1440p)
If only the shoe was on the other foot, you would have praised Turing.
1060 ($ 249,-) >> 2060 ($ 349,-) (You will find me saying the 2060 is the only interesting release this gen, but comparing to a 1060 is not correct)
1070 ($ 379,-) >> 2070 ($ 499,-)
Should I continue? ... this isn't rocket science. Perf/dollar is 100% stagnant from Pascal to Turing and the only interesting release is found in the midrange, with performance that was available for over 2 years now.
There is absolutely nothing to praise here, and this has been clear as day since this generation was announced. Nvidia does its usual twist and bend of the numbers to extract more cash from a market that has been starving for upgrades for years, the question is should you fall for it, or use common sense and hard numbers that factor in price. The reality is, if you look at TPU reviews, barely anything has changed across the board in terms of realistic purchase options - the stack got updated and we barely gained anything. A few 5-8% perf jumps at the same price point is hopeless, (that is what AMD managed with just
driver releases over the time Pascal was released...for some perspective) - especially with twice as much time in between releases as usual.
But let's drive this home anyway, because apparently I'm saying strange things to you
970 >> 1070: +40% perf / $329,- vs $ 379,- (Let's say the usual, generational +30% got a little bonus and it costs us 50 bucks extra, reasonable!)
980 >> 1080: +51% perf / $549,- vs $ 599,- (Same deal, bigger jump)
Yeah, business as usual hm?
My god... I thought we had smart people here.
The thing is, numbering is a little misleading. If we look at price, performance and power draw, RTX 2060 is the successor to GTX 1070(Ti), RTX 2070 is the successor to GTX 1080 and the RTX 2080 replaces GTX 1080Ti. Even then, the new cards are faster. How can someone look at these cards and conclude "the only performance uplift is found in the 2080ti" is beyond me. Yet it happens.
Titan was faster too back in the Kepler days, but nobody told you it was an interesting GPU to buy for gaming.
I think its about time people cooled down their upgrade itch a bit and look at the hard numbers, most notably the one with the dollar sign in front. There is little to be gained here for a high end Pascal user, which most of us are.
