HBM2E memory with a peak bandwidth of up to 716 GB/s is accetable, better than Titan V.

But a step down from 4kbit wide HBM2 1TB/sec on [URL="https://www.techpowerup.com/gpu-specs/radeon-vii.c3358"]Radeon VII[/URL]

If I'm understanding correctly the memory bandwidth may scale with tile count, meaning the 2T version could exceed an R7's bandwidth.

The one you linked mentioned FP64 support at least in the xe-hp variant. I would imagine that we will see 1/32 speed or similar dp support in the consumer variant as well for code compatibility.

[QUOTE=henryzz;588217]The one you linked mentioned FP64 support[/QUOTE]"Supported". No performance number, as I said. "Support" means > 0 DP FLOPS is all. Windows 10 Calculator qualifies for that. It could be DP/SP 1/64 and "supported". By emulation in the driver might still be called supported.

No, because it is not hardware. calc.exe needs hardware to execute DP instructions. You cannot compare software to hardware here. Only if you extended the meaning of "support" to "make use of", it might qualify. But this meaning would make no sense for hardware the other way around.

Edit: Additionally, calc.exe does not provide any kind of interface for executing DP instructions. The GUI is definitely not an interface for IEEE 754 numbers, not even in the programmer view.

I only used calc as an extreme example of DP support/implementation with very low nonzero throughput. But there are folks who try interfacing to such things.
