Factory Factory posted:All this time I've taken IPC to refer to Instructions Per Clock (which Intel is also kicking AMD's butt with). The More You Know. When concerning CPU performance, it does mean Instructions Per Clock. While a fast CPU (and especially fast/efficient core/socket interconnects) may speed up Inter-Process Communication, it is mainly a software implementation issue and a not a metric for CPU speed. Unless there are benchmarks showing a marked performance advantage for Intel vs. AMD in Inter-Process Communication, which is independent of other characteristics of the CPUs (such as memory, cache or integer performance), I think Agreed is confused.

I was a bit hasty, some parts of the microarchitecture can have a large impact on some IPC performance, such as the speed of execution of instructions that support locking primitives such as CMPXCHG, which has IIRC indeed seen some performance gains in later Intel CPUs. Benchmarking CMPXCHG and similar can give you some indication of the CPU's IPC performance, but since there a some types of IPC of which does not necessarily depend on hardware support, it will only be limited to measuring just a subset of possible IPC mechanisms. And in any case, it will tell you nothing of the general performance characteristics of the CPU. A CPU that has fantastic lock performance can sucks at everything else and vice versa. IPC meaning Inter-Process Communication here of course  A fast CPU will probably be pretty fast at IPC as well, but as said, it's not a metric like Instructions Per Clock (which has it's own problems).
