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.
In the integer performance test, there's virtually no advantage to the 3770K, but it posts surprisingly strong results in the floating point test, beating the 2600K by an amazing 67%!
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. Again, the 3770K is no better than the 2600K at stock clock speeds, but improves dramatically when overclocked.
Interestingly, the Ivy Bridge CPU posts slightly lower scores in the Compression and String benchmarks than does the older Sandy Bridge CPU.
