Windows 7 beta 1 performance - How does the OS compare to Vista and XP?
 

Rather than publish a series of benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), I’ve decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests to find out which OS comes out top. These series of tests will pitch Windows 7 build 7000 32-bit against Windows Vista SP1 32-bit and Windows XP SP3 32-bit. The scoring for each of the tests is simple. The winning OS scores 1, the runner up 2 and the loser scores a 3. The scores are added up and the OS with the lowest score at the end wins.
