Cray & AMD win supercomputer contract

I have posted these news mainly because some time ago there were here some comments about Intel winning the Aurora contract, supposedly because of a better power efficiency than AMD.

I would like to point out that the Frontier supercomputer has a public specification for the power consumption: 300 kW per cabinet, i.e. 30 ... 40 MW total.

On the other hand, there is no information about the Aurora power consumption, but it is likely that even at 2/3 of the Frontier throughput, Aurora might consume more power, simply because the Intel CPUs will use an older technology.

Nevertheless, Intel Xe GPUs will probably be made on 10 nm, because they do not need high clock frequencies, so for GPU tasks the power efficiency of Aurora might still be good.

"We were told that these future EPYC CPUs will add additional instructions and have an optimized architecture for AI and supercomputing."

It would be interesting to know if these extra instructions are AVX-512 or the extra ML instructions of Cascade Lake / Cooper Lake, or they are something else.
