I stand by my statement "you give me GDDR or HBM at DRAM prices, and I'm ready to 'suffer' the consequences in terms of performance",
if only because I'd sell those HBM and GDDR chips at a nice profit ;-)
I had seen and noted that Xbox sell-off board and I remember there have been other "console PC" designs e.g. in China which used GDDR exclusively evidently to simplify the design and because expandability wasn't part of it.
But this board has too many unknowns right down to the number, specs and interface of the chips and then evidently they had to use a discrete GPU for the gaming tests.
And I'd hazard that even if GDDR latencies were indeed penalizing code latencies, a V-cache and GPU code gains on the graphics side might largely compensate for that.
And then please remember that the original discussion was about HBM.
And there was a reason that Intel tried to fit the HMC alternative on their HPC designs and are now putting HBM on CPUs: they obviously don't do it to increase latencies.
You'd still find some HPC use case that won't fit that mold, but that's basically hyperscaler credo: once a use case's scale is big enough, only a bespoke design will fit it!
