iMac Pro - is W Xeon Processors (with lower TDP than the retail counterparts)
No Intel Xeon W-2145 @ 3.7GHz
Apple will use Intel Xeon W-2140B @ 3.2GHz ( 8 cores / 16 threads, CPUID 0x050654)
No Intel Xeon W-2155 @ 3.3GHz
Apple will use Intel Xeon W-2150B @ 3.0GHz (10 cores / 20 threads, CPUID 0x050654)
(Maybe no Intel Xeon W-2195 @ 2.3GHz, another OEM SKU for Apple for the 18 Cores)
Credit to
PIKERALPHA for the findings.
No Xeon Gold+ for iMac Pro, it makes sense as Xeon W is for mainstream single socket work station. Xeon Silver/Gold are for dual socket boards/systems. Unfortunately there is no updates yet from Apple on Mac Pro 7,1.
