PCMark 8 is the latest version in the series of PC benchmarking tools by Futuremark. It is fully compatible with Windows 8, and can be run under Windows 7.
Just like in previous tests that we did with these two CPU's, we find the results will be very close to those tests. You can see in the PCMark 8 tests that both the i7 4771 and E3-1285v3 are very close in performance, with the i7 4771 getting slightly better results on the P9D WS. We used a 690gtx that we had in the lab to run this test, which explains the increase in points on this test.
These two CPU's are very close in specifications with only 100MHz different in stock and turbo speeds.
PassMark performance test runs 32 tests including CPU, 2D & 3D graphics, disk, and memory tests, to come up with an overall system ranking that allows you to determine how fast your computer is in comparison with other systems.
Here we see only a slight difference between these two CPU's, which is something that will be common in the rest of the tests.
