Has someone experience with the (new) Radeon RX 6600 XT graphics card?
I am interested, because this card is available, relatively affordable and has low power consumption.
Of interest here is the megapixel/second performance with Deep Prime.
There is a benchmark spreadsheet here https://docs.google.com/spreadsheets/d/1Yx-3n_8D3OreyVwQLA-RVqiQCAgNdXDkxScpXTur1Gs/edit#gid=0, but this card is not listed yet.
Glad you inserted ‘relatively’ before ‘affordable’ there 
It’s around 400GBP!

Given that the realworld FP32 GFLOPS throughput seems to be the most relevant thing for DeepPrime, my best guess is it should land somewhere in the Ballpark of a RX Vega 64.
But the Architecture is a bit newer and since it’s somewhat of a split in half N21/ RX 6900XT (IF Cache aside) which performs quite well given it’s raw GFLOPs, it might even perform be a bit better than the old Vega10 GPU.
However since the only RDNA2 in the spreadsheet is my 6900XT and the other RDNAs in there are somewhat lower-end Cards it`s a bit hard to tell IMHO.
I think you’ll have to try it out, but i don`t really think it will underperform!
