Experiment: Comparing Four Quad-Core Architectures At 2.8 GHz

Benchmark Results: Synthetics

The AES encryption test results closely match our experience with performance among the four competitors.

The memory bandwidth benchmark shows that Intel’s memory and cache architecture delivers impressive gross performance numbers.

PCMark Vantage’s memories test confirms the Sandra findings, but the differences are smaller.

PCMark Vantage tells us that Core 2 Quad and Phenom II X4 are basically identical when it comes to performance. It also reveals that the real world advantage of Core i7 on LGA 1366 over Core i5 on LGA 1156 in this particular metric is negligible.
