Maybe this is what he means as I've seen this advice several times, but iMacPro1,1 is first for Intel Xeon Skylake CPU without iGPU, which is quite far from our i7 Coffe Lake (Refresh in my case) CPU. For me using iGPU is not mandatory but I use it now to help the dGPU to stay cooler (which is not really a success...).
Maybe iMacPro1,1 handles graphic power management for RX 500 cards better than iMac19,x but I have doubts about that as iMacPro1,1 only has Vega while iMac19,x has plenty of RX 500 dGPU.
I agree, it would not seem logical. But again, if anyone can show data that GPU power management is better, I'd give it a try. Until then I prefer not to change SMBIOS because of issues with account reactivation.
