NVIDIA GeForce RTX 3070 Ti / RTX 3080 Ti Compute + Renderer Performance Benchmarks
Overall the performance of the RTX 3070 Ti and RTX 3080 Ti graphics cards are right where one would generally expect for these SKUs fitting into NVIDIA's RTX 30 series line-up...
For many of these compute benchmarks, the RTX 3080 Ti had larger uplift over the RTX 3080 than the RTX 3070 Ti did from the RTX 3070.
On a performnace-per-Watt basis, the new Ti cards were actually less power efficient than many of the RTX 20 series cards tested.
