Compute & Synthetics
Moving on to the low-level compute guts of the cards, we take a look at compute and synthetic results starting with tensor core accelerated GEMM.
While using binaries compiled for Volta, Turing is backwards compatible in that respect as it is in the same compute capability family (sm_75 compared to Volta's sm_70). In terms of compute resources, the RTX 2080 Ti's 544 tensor cores and 1545MHz boost clock is not far off of the Titan V's 640 tensor cores and 1455MHz boost clock, so the latest Turing-optimized binaries should better reflect the RTX 2080 Ti's raw GEMM acceleration capabilities. Likewise for the 368 tensor core RTX 2080, whose tensor-accelerated HGEMM performance in TFLOPS is somewhere around 20% less than the RTX 2080 Ti.

Way too expensive. If those cards were the same price as the 1080 / TI it would be a generation change.This actually is a regression, the price has increased out of every proportion even if you completely were to ignore that newer generations are EXPECTED to be a lot faster than the older ones for essentially the same price (plus a bit of inflation max).
paying 50% more for a 30% increase is a simple ripoff. no one should buy these cards ... sadly a lot of people will let themselves get ripped off once more by nvidia.
and no: raytracing is not an argument here, this feature is not supported anywhere and by the time it will be adopted (if ever) years will have gone bye and these cards will be old and obsolete. all of this is just marketing and hot air.

There are those who claim buying RTX to get the new features is sensible for future proofing; I don't understand why they ignore that the performance of said features on these cards is so poor. NVIDIA spent years pushing gamers into high frequency monitors, 4K and VR, now they're trying to flip everyone round the other way, pretend that sub-60Hz 1080p is ok.And btw, it's a lot more than 50%. Where I am (UK) the 2080 Ti is almost 100% more than the 1080 Ti launch price. It's also crazy that the 2080 Ti does not have more RAM, it should have had at least 16GB. My guess is NVIDIA knows that by pushing gamers back down to lower resolutions, they don't need so much VRAM. People though have gotten used to the newer display tech, and those who've adopted high refresh displays physically cannot go back.

I wonder if NV did not hike prices so much on purpose so they don't have to lower existing GTX prices that much. There is still ton of GTX in stock.poohbear - Friday, September 28, 2018 - link
Why the tame conclusion? Do us a favor will u? Just come out and say you'd have to be mental to pay these prices for features that aren't even available yet and you'd be better off buying previous gen video cards that are currently heavily discounted.zozaino - Thursday, October 4, 2018 - link

Why does the 2080ti not use the tensor cores for GEMM? I have not seen any benchmark anywhere showing it working. It would be a good news story if Nvidia secretly gimped the tensor cores.
