7770 has 72GB/s, XOne's main memory is 68.3GB/s - additional XOne's enhancements will certainly boost performance of its GPU, but so will additional enhancements in PS4's GPU. Hence, I think 7850vs7770 comparison is fair starting point.

The problem with your number is that you are not taking in account of the eSRAM(very low latency) which has a higher bandwidth than the gimp one in the 7770 on top of other possible enhancements and that the DDR3 has a lower latency than GDDR5. I'm just trying to be fair. :P


I am actually, but I'm also taking into account enchancements implemented in PS4's GPU that Cerny talked about. That's why I'm comparing vanilla 7850 and 7770, though both PS4 and XOne have better GPUs in reality.

Not that it will matter for the most part, except for few exclusives - as someone mentioned before, people have problems seeing difference between next and current gen (which is quite...amusing), though there is 8-12x difference in raw proccesing power between them.
