The Marques Brownlee illustrates the GPU score of a single AMD Radeon Pro W6900X MPX module (2021 Q3) in the 2019 Mac Pro is 168k in Geekbench vs 104k for the M1 Ultra - ie 60% faster.
Roughly speaking a fully loaded (2 x MPX) 2019 Mac Pro would be 3.2 x the GPU performance of a M1 Ultra (with an 'Infinity fabric' cable connecting the GPUs). With a Vega Duo matching the M1 Ultra in some of the synthetic test - 4 x M1 Ultras might only be comparable to a fully loaded 2019 Mac pro.
So .. 4 x M2 Extremes might hit the sweet spot. Circa 128 performance CPUs cores is way more than is needed.
+) Would Apple licence AMD's Infinity Fabric v3 (which is coherent but not particularly fast) between its own 'Sleds'?
+) Will Apple adopt an open standard (like PCIe5) so that AMD or Intel can make GPU only sleds?
+) Will Apple risk moving Metal towards an APU (GPU + CPU with unified memory) optimised version?
On another note - it looks like M2 production may be delayed by a quarter. That could mean that any MacPro announcement in June (WWDC) will be a sneak peek with hardware availability in Q4.
