SiSoft Sandra theoretical testing greatly favors Intel's Core i7 920 processor, although it's difficult to find real-world situations where this kind of performance scaling exists. AMD's Phenom II X4 985 Black Edition comes in exactly where it is supposed to in this benchmark, just a bit ahead of the X4 955 BE processor.

The Core i7 once again demonstrates its incredible theoretical performance in Sandra. The triple-channel memory interface allows it to post huge gains in the memory bandwidth test. The AMD Phenom II X4 965 Black Edition holds its place, incrementally faster than the Phenom II X4 955 BE CPU, but distantly behind the results posted by the Core i7 920.
