“Interestingly, the iMac Pro models benchmarked appear to have custom, downclocked Xeon chips that Intel hasn’t publicly announced yet,” Rossignol reports. “There is a benchmark result for a model with a 3.2GHz 8-core Xeon W-2140B processor, while a third listing exists for a model with a 3.0GHz 10-core Xeon W-2150B chip. All of the models are identified as ‘AAPJ1371,1,’ and unlike other Xeon chips, the processors have a ‘B’ suffix.”
“MacRumors spoke with Geekbench founder John Poole, who speculated that the iMac Pro may require chips with lower thermal design power, and thus lower frequencies, due to its all-in-one form factor,” Rossignol reports. “The multi-core Geekbench score for the 8-core model averages out to 23,536, which is the highest performance of any iMac ever… The higher-end 10-core iMac Pro has a multi-core score of 35,917… And that’s not even looking at the 18-core iMac Pro, which hasn’t been benchmarked yet and will surely blow every other Mac out of the water—at least until the modular Mac Pro is ready.”
