When they moved to Intel, the Mac Pro 1,1 used 64 bit Xeons so was comparable to the PowerMac G5. Since the "consumer" Mac was 32-bit, there really wasn't a "regression" per se. The real problem is the original EFI was 32-bit, and the main reason there is such a harsh cut off on some of the older hardware that should still run the modern OS X, 32-bit EFI meant a limitation in Memory addressing. I have a 32/64 Mac Mini that can only address 3 GB of RAM. The processor can do 64-bit, and I have run 64 bit Red Hat on it, but it will not address larger memory.
