Radeon RX 6750XT already being tested
The Radeon RX 6750XT is the upcoming refresh of RX 6700XT with faster memory and higher clock speeds. This is the Navi 22 GPU based upper-midrange model with 12GB GDDR6, now likely clocked at 18 Gbps. Higher memory frequency and rumored increase of board power, are expected to provide a noticeable, but not significant performance uplift. It might be just enough to tackle the upcoming Intel Arc desktop cards, though.

This RX6750XT might not make a big difference in crypto mining, that 50XT difference won't be huge in hashrate performance, now that intel GPUs are around the corner all graphic cards value will decrease in coming weeks.

nice. looking forward to see hashrates.

From the change and the addition of these cards,the best refresher as you said is the 6750 XT as it will be 18 Gbps which is even higher than the Rx 6800 XT,hopefully this refresher will be able to achieve that 70 Mhsh or at least 60 Mhsh or I am dreaming to big maybe.The other refreshers I didn't see any improvement,the 6950 XT it will still have the same number of stream processors and VRAM as the 6900 XT.

I would not buy Radeon with the current uncertainty around ETH PoS. Unfortunately, I'll have to go with Ngreedia GreedForce yet again.

As good as these new AMD graphic cards are Nvidia graphic cards are still better because they support more algorithms than AMD graphic cards, if truly ETH merge will happen later Nvidia will be a better option, more futuristic IMO.

If you plan to mine ETC or some type of Progpow - i would prefer AMD cards in any case. And Dual Mining TON or ALPH is better on AMD cards, they can handle this better than Nvidia in most cases, and some more dualmining options are on the road.
Beamhash is also a good algo for AMD and Cryptonight Heaven also. Over the years i had much more problems with Nvidia and this LHR shit 

6650XT you can expect around 35mh @ 70w for ETC/ETH, Kawpow maybe around 18mh.
6750XT climb to maybe around 50 - 52mh @ 100w for ETC/ETH.
6950XT achieve around 65mh in my opinion.

I think you meant to write RX6650XT instead of RX6750XT because that RX67** is far more powerful than any RX66**, that number 7 indicates that its more superior in raw power than number 6 or are you new to crypto mining? Numbers is how we identify which will be more powerful or weaker.
