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 FX-8350's performance on the Integer section of the benchmark is amazing...so much so that I must chalk it up to a problem or compatibility issue between the FX-8350 and this particular benchmark. The Float and Prime benchmark results mirror what we saw in the FX-8150 review, with the AMD CPUs racking up substantial wins.
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; probably since each two-core "module" in the CPU has two 128-bit floating point units. 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, and the AMD CPUs rack up a substantial win in both benchmarks. But enough with the synthetic benchmarks; let's move onto some more real-world applications.
