Next, we measured the amount of time required for LAME to encode a WAV to an MP3. The song we used for this was Klein Mandelbrot from the Blue Man Group.
Although glxgears is quite subjective and doesn't reflect real-world results, we took the average of five runs to better compare the Intel Celeron D and Pentium 4.
To wrap up the CPU benchmarking, we ran three Opstone benchmarks from Blue Sail Software. The benchmarks ran were Vector Scalar Product, Sparse-Vector Scalar Product, and Singular Value Decomposition. These Blue Sail Software benchmarks are geared to appraise the floating point-performance of CPUs. For all of the testing in this article, we used the Pentium 4 build of each of these benchmarks, which are SSE & SSE2 optimized.
