PassMark PerformanceTest 7.0
The PassMark PerformanceTest allows you to objectively benchmark a PC using a variety of different speed tests and compare the results to other computers. PassMark comprises a complete suite of tests for your computer, including CPU tests, 2D and 3D graphics tests, disk tests, memory tests, and even tests to determine the speed of your system's optical drive. PassMark tests support Hyper-Threading and systems with multiple CPUs, and allow you to save benchmark results to disk (or to export them to HTML, text, GIF, and BMP formats).
Knowledgeable users can use the Advanced Testing section to alter the parameters for the disk, network, graphics, multitasking, and memory tests, and created individual, customized testing suites. But for this review I used only the built-in CPU tests, which aren't configurable. The CPU tests comprise a number of different metrics. The first three I'll look at are integer performance, floating point performance, and a benchmark that finds prime numbers.
The CPU Integer, Float, and Prime tests benefit from overclocking, with the ASUS scores increasing by 18% in all cases.
SSE stands for "Streaming SIMD Extensions", and are instructions that handle multiple chunks of data per instruction (SIMD = Single Instruction Multiple Data). SSE instructions work on single-precision floating point data and are typically used in graphical computations. SSE was Intel's response to AMD's "3D Now", which itself was a response to Intel's MMX instructions. Overclocking nets the ASUS boards 19% extra in the SSE test and 18% in the Encrypt test.
The Compress and String benchmarks show an 18% and 13% improvement, respectively, with overclocking.
