This simple integer benchmark focuses on the branch prediction capabilities and the misprediction penalties of the CPU. It finds the solutions for the classic “Queens problem” on a 10 by 10 sized chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores. For example — with HyperThreading disabled — the Intel Pentium 4 Northwood based core processors get higher scores than the Intel Pentium 4 Prescott core based ones due to the 20-step vs 31-step long pipeline. CPU Queen Test uses integer MMX, SSE2 and SSSE3 optimizations and is usually a good indication of how efficient a CPU’s branch prediction abilities are.
