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.

What AMD needs right now is marketshare so more stuff gets written in something cross-platform instead of cuda. I'd imagine that 1/2 has at least been discussed at great length for this card.

It's looking like that "something cross-platform" will be cuda, given that AMD's latest approach is to implement a compiler to convert cuda to "hip."

MI50 has ECC RAM support. That's absolutely necessary for high-end scientific compute.

Not at a 10x price difference it isn't, at least if you're at all price conscious and looking for workstations / small clusters. This makes it far cheaper to just re-run simulations as necessary to get the same statistical guarantees with regards to memory corruption errors.

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.
