Here are the results from each of the benchmark tests. Each test was run
three times, and the average taken from all three runs.
No significant variance was seen between the three runs in any of the
tests, a consistency that gives me confidence in the results.
Boot time
The Windows 8 RTM has managed to shave another second off the total boot
time to a usable desktop, although the boot time to logon remains the same as
it was for the Release Preview.
Audio
transcode time
There was
no noticeable difference between Windows 8 RTM and the Windows 8 Release
Preview, though both are significantly faster than Windows 7.
The
improvement is more noticeable when large files are being transcoded.
Video
transcode time
Windows 8 RTM shows a slight improvement over Windows 8 Release Preview,
which was itself comfortably faster at transcoding video using Handbrake for Windows 7.
Again, this becomes more noticeable when transcoding larger
files.
PCMark 7
Once again, the Windows 8 RTM ends up with a far superior score than Windows 7 The bulk of the improvements were primarily made by a healthy
increase in the "creativity" score, which measures multimedia and
DirectX performance.
However, the difference between the Windows 8 RTM, Windows 8 Release
Preview and Windows 8 Consumer Preview is negligible.
3DMark 11
There appears to be no significant difference between the operating
systems.
Furmark
This test showed no significant difference between the operating systems.
Cinebench
11.5
OpenGL is still slightly faster on Windows 7 but the difference between
the operating systems bears little significance.
Heaven 3.0
the minimum FPS score was lower than for Windows 7 which indicated that
in-game FPS drops on the new operating system were greater than they are on Windows 7. However, with the Windows 8 Release Preview, Microsoft tightened up
the code and bought performance to that of what you'd expect from Windows 7
With the RTM release, it seems that Microsoft -- quite possibly with the help
of more mature graphics card drivers -- have improved the score even more.
This is good news for gamers hoping to make the switch to Windows 8.
Alien vs.
Predator
There appears to be no significant difference between the operating
systems.
