Since 2304 (36CU) is ~5.5TFLOP so my money is on a full fat Polaris 10: 2560 cores, which should push it over 6. That's more than PS4 Neo's 2304 (36CU). 320GB/s = 256bit with GDDR5X at 10Gbit/s. It's entry-level GDDR5X so should be plentiful volume by 2017. Eight cores very likely still based on low power x86 not Zen to keep platform compatibility and cost and die size as low as possible, although likely upgraded to Puma(+) and clocked at low-2GHz up from 1.6. No word on whether they dropped the eDRAM in order to favour going GDDR5X, but it's a likelihood since the increasing Xbox - PC alignment requires it being as PC-like as possible to please developers making UWP apps. Partners at Computex tell me Oculus is pushing a lot of resource Microsoft's way, away from PC, in order to focus on Xbox VR in Q117. Oculus does what it does best: hardware (on a fixed platform), and Microsoft has the software and channel for selling games and MS gets the Oc brand to enhance its VR credentials. As an offshoot of all this, AMD will have IP for a 2560 core Polaris 10 part with GDDR5X somewhere in its arsenal. RX 490? Then Vega becomes new Fury?
