Its an interesting design for sure. 4x Stacks of HBM2 means 1TBps memory bandwidth at 16GB. Only 60-compute units enabled (maybe 4-CUs are expected to break during manufacturing? Its a weird number for sure...). Since it shares dies with the MI50, the Radeon VII will have 1/2 speed double-precision, making this the cheapest high-performance double-precision card in existance. ------ FP16 compute is supported at doubl…
There's no guarantee this won't have gimped FP64, Hawaii for example had 1/2 rate FP64 but the consumer cards were 1/8 speed. But even 1/8 would leave the 1/32 NVIDIA cards in the dust. If they don't gimp FP64 it won't leave a whole lot of reason to buy the MI50 for probably 10x the price.
It's not gimped according to Ryan Smith from AnandTech: https://twitter.com/RyanSmithAT/status/1083959608371175424
Which means it destroys it's only real competitor for consumer FP64 - the Titan V - which costs 3000 Dollar.
