If the A770 can touch the heels of the 3070 and 6750XT, then I think it'll be a win for Intel and they'll be able to move those (assuming pricing is somewhat correct). They may have missed the Crypto-train, but at least they can make an argument under the $400 mark, for sure. There's a lot of people that will be happy to get GPUs under and around that price point.
Still... With AMD and nVidia's next gens close by, Intel better act soon. From the announcement/reveal to shelves, there should be less than a month IMO. At worst a month, since AMD and nVidia will say something at Computex as well.
Regards.
