PassMark Performance Test 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. PassMark computes a "CPU Marks" score based on the scores of the individual tests in each test suite. For this review I used the CPU, 2D Graphics, and 3D Graphics tests.
In this benchmark we see that the Z68A-GD80's iGPU performance is noticeably behind the P8Z68's performance. Its 2D Marks score is 21% lower (528 vs. 669) and its 3D Mark performance is 15% lower.
OC Genie's overclock increases CPU Marks by 20%, 2D Marks by 34%, and 3D Marks by 17%. Virtu's i-Mode does kick in for the 3D Marks (note the 2940 score). Note, however, that this is slightly lower (about 6%) than the same video card running "natively" on the P67 platform. Virtu's i-Mode works by copying the contents of the video card's frame buffer to the iGPU buffer, and this imposes a small performance penalty.
