Over at Lifehacker they decided to put Microsoft’s claims to the test and ran a few speed tests to compare the Windows8 developer preview with Windows 7.
However they didn’t conduct those usual tests which are just a bunch of synthetic benchmarks which simply churn out numbers and don’t really make sense to the average user. Instead they performed an array of everyday tests where you could visually see the difference for yourself. All the tests were performed on a clean installation of each OS with the same programs installed.
The system used to test them on was a 3.8GHz Intel Core i7 with 6GB of RAM, a 2TB Harddrive and an Nvidia GeForce 9800 GT.
So the results? Well hands down Windows 8 won overall, and beat Windows 7 in nearly every single test that was carried out. However there was one test where it absolutely blew Windows 7 away, and that was the boot time. When Windows 7 was released it did boot surprisingly quick, but Microsoft have put a lot more work into Windows 8′s boot time, as a result it thrashed Windows 7 in this test, booting in just 10 seconds compared to Windows 7′s 35 seconds.
