Hey guys- hoping someone could help me get up to speed on multi processor systems since there doesn't seem to be a lot of focus on them lately (what with moar cores happening just fine on one package)
However it seems to me like if you really wanted a ~12 core system that didn't compromise at all on IPC, you could probably do that with two Intel Hex cores (such as the Xeon E5)
I remember these types of rigs were pretty common when things like the EVGA SR-2 motherboard were popular. But what are the more modern solutions?
It's very confusing to me because it seems not all Xeon E5's support 2P (even SB-E ones), I'm really guessing things like the 39XXk CPUs don't support it, and I don't really understand the benefits between SB-E, IVB-E and (Haswell-E?)? Are they IPC or just power consumption?
Do any 2P motherboards for SB-E or IVB-E support overclocking? At least bumping up all the cores to max turbo freq?
EDIT: Well I did some extra research and there are boards like the SR-X that support 2x Socket 2011, but from what I can gather you have to use Xeon E5's, and all the SB-E and IVB-E ones are completely locked down for overclocking -_-.
That really hurts the "bang for the buck" ratio when compared to something like an overclocked 3930k or 4930k
I guess the last question is are there any OS limitations to be aware of? Does Win 7 Pro only like a certain number of physical processors and/or max # of cores/logical threads?
