As long as it’s better value than Nvidia – you know, like, less than £1,000 or whatever Nvidia prices cards at these days - it will sell and possibly bring down some Nvidia prices. Win Win. 90% of the speed for 70% of the price is a no-brainer for me.
Only that won't happen. Why do you think AMD is going to do you any favours? VEGA will be priced according to what the market will bear, and it has been proven the market will bear a high GPU price at the top end. Of course, it all depends what the performance level of VEGA is, but if it's around 1080 performance, expect a 1080 price. Do not expect it to offer 1080 performance levels for the price of a 1070... that will NOT happen.
