NVIDIA GeForce GTX 680 To RTX 2080 Ti Graphics/Compute Performance

Lastly is a look at the overall GPU temperatures of the tested graphics cards. The GeForce RTX 2080 Ti Founder's Edition card had an average GPU core temperature of 67 Celsius which is lower than the other cards tested. The peak operating temperature and also minimum temperatures were too a few degrees lower.

The GeForce RTX 2080 Ti did consume the most power of the tested GPUs... The total AC system power consumption average when running with the RTX 2080 Ti was 273 Watts and a 378 Watt peak. That's compared to the GTX 1080 Ti with a 249 Watt average or 349 Watt peak.

Hopefully you found these numbers useful. The GPU compute performance improvements were most profound for the GeForce RTX 2080 Ti and I have a lot more OpenCL/CUDA tests forthcoming on Phoronix.
