12 channels ddr5 = 400 gbps or more?

The chiplets aren't the problem here, it's the socket and motherboard that I'm worried about. Imagine running less than 32 cores on a 7004 system. It just wouldn't really make sense, and would be disproportionately expensive. I'm not even sure that will be an option. If AMD doesn't offer an electrically simpler socket, they're kinda just handing over low end servers to Intel. Granted, maybe Threadripper Pro will end up being the new low end server market, assuming those chips don't get this gargantuan die.

We took a hybrid approach to a recent box we bought. We got it with two 16-core EPYC processors. That means we have 64-cores at almost the highest clock rate available in the series. It is a very, very fast machine on our workload.
