Does anyone know how the processing power of a Radeon VII compares to a Radeon Pro Vega II or Radeon Pro Vega II Duo?
The VII is a slightly kneecapped Instinct MI50. the Pro Vega II is a modified MI60. There are 4 more CUs ( 256 more stream processors ) and twice as much HBM2 ( 32GB )

If look at the theoretical peak performance numbers for MI50 and MI60 that is probably illustrative of the gap. ( 13.3 vs 14.7 TFLOP single precision so around ~10% )
If need to load a larger data set into HBM RAM then it is pragmatically a larger gap (e.g, if blow past the 16GB limit of the VII ) . If two GPUs need to swap data then the Duo can have ever larger edge ( since can do that over Infinity Fabric).
He says
2 x Radeon Pro Vega II Duo = 57 teraflops
2 x Nvidia RTX 2080 ti = 27 teraflops
TFLOPs of what? FP16? But FP32, no. Not even AMD is claiming that on their marketing bragging pages. The MI60 is 29.5 TFLOP FP16. ( 2 x is 59 so 57 is ).
So maybe a Radeon Pro Vega II is equivalent to a Nvidia RTX 2080 ti, so I'm wishfully thinking they will render in Redshift & Octane in similar speeds. If thats true hoping they will be similarly priced also.
Not sure how they would be similarly priced at all. Pro Vega II has 32GB of HBMv2 memory and 2080 ti has 11GB of GDDR6. Vega II an large interposer to hook that all together versus VRAM soldered to logic board. (i.e., is more space efficient but that costs money) That's a huge price gap right there. Vega II is 7nm (bleeding edge fab for that die size ) and 2080 Ti is mature 12nm. AMD stripped Infinity Fabric from the Radeon VII so it is up in the air to see what price AMD and Apple are going to charge to leave it on,
So maybe a Radeon Pro Vega II MPX would be $1200, Radeon Pro Vega II Duo MPX would be $2400, and two Radeon Pro Vega II Duo MPX would be $4800.
I think you are letting the Founders edition price for the RTX 2080 Ti price anchor the outlook here rather than starting with what AMD's bill of materials costs are and going forward from there with margins that AMD and Apple are likely to impose.
This is probably not going to be huge winner on best $/performance. it will more so be on the raw perf number coupled to what runs on macOS. The Pro Vega II is probably closer to $2K than $1k. The Duo is probably closer to $4K than $2K. And two Duo is probably closer to $8K than $4K (i.e., more than the base entry entire system price ).
