New drivers for Windows 8 may mean a world of difference
Metro fan or not, Windows 8 is a performer
The computer geeks over at
run a few benchmarks on the
consumer preview for Windows 8
, comparing it to Windows 7. The findings indicate that Windows 8 offers improved performance on almost every test.
reports that the consumer preview of Windows 8 was generally faster, and often much faster, than Windows 7.
used a test machine running an Intel Core i5-2500K at 3.3 GHz, 8 GB of RAM, 1 TB hard drive, and an NVIDIA GTX 560 Ti video card. The same machine had previously been subjected to an identical battery of tests running Windows 7. The machine was benchmark using WorldBench 7 tests. WorldBench results showed that Windows 8 was 14% faster than Windows 7. The publication reports that a difference of 5% or more on WorldBench is noticeable performance wise, so 14% is significantly faster.
Using the same computer benchmark and PC, Windows 7 scored 100 while the system running Windows 8 scored 114. Start up time for the Windows 8 machine was 36.8 seconds compared to 56.2 seconds for the same system running Windows 7.
Web performance for the Windows 8 machine using WebVizBench gives a score of 28.6 frames per second compared to 18.9 frames per second for a Windows 7 machine. Interestingly, when running Windows 7 the test machine was faster for content creation compared to running Windows 8. The difference was slight though and new drivers for Windows 8 machines can significantly improve performance.
It's also worth noting that Futuremark is working on updating the PCMark benchmark suite for Windows 8. The office productivity tests were performed using PC Mark from Futuremark and an upgrade to the software for Windows 8 could mean significantly improved performance. As it stands now Windows 7 was quicker in both content creation and office productivity on PCMark. In Office productivity the Windows 7 system scored 2280 compared to the 2099 of the Windows 8 system.
Windows 8 could be significantly faster than Windows 7 on the same computer once drivers and benchmarks are optimized. That, however, isn't likely to happen until Windows 8 launches or is close to launch.

Video encoding is faster?

Why would video encoding be any faster on Windows 8?
At least with software encoders like x264, they are entirely CPU bound. The operating system should have very little effect on most CPU-bound tasks, unless they make a lot of kernel calls. Video encoders shouldn't be making too many of those (occasional disk writes, etc.)
I'm happy that it appears to be faster, but confused as to why.

I believe it has to do with the fact that by default, Win8 has less unneeded services running in the background.
