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.
Here we see more of what we expect: Intel wins in integer horsepower, and AMD wins for floating point...and by a very large margin, with the stock-clocked 1100T even beating the overclocked 2500K. AMD's FX-8150 takes the win in the Prime Number benchmark as well.
SSE stands for "Streaming SIMD Extensions", and are instructions that handle multiple chuncks 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. Don't you love competition? AMD's current implementation still wins in this benchmark. The Encryption benchmark has historically been AMD's to win, and AMD does dominate here as well.
The Compress and String benchmarks are both integer-based, but the FX-8150 ekes out a win in both benchmarks. But enough with the synthetic benchmarks; let's move onto some more real-world applications.
