850k cores apparently. We have EPYC chips with ~100 cores at ~200w TDP. So each core is around 2W in the AMD chips. Core voltages are ~1v with modern CPUs. So

850k cores apparently. We have EPYC chips with ~100 cores at ~200w TDP. So each core is around 2W in the AMD chips. Core voltages are ~1v with modern CPUs. So that's 2A per core. 850k cores at 20kA is very much lower than the AMD chips. Must be massively parallel, lower-performing cores. But it's quite feasible that it needs 20kA. The CS-2 system on their website specs out at 23kW peak. So all this lines up with each other. As far as benchmarks and utility of such systems, I am not sure if they've proven it out.
