PCWorld Labs Staff compared the performance of Windows 7 and the pre-release version of Windows 8 (Consumer Preview), which spread  started February 29.

For testing we used a computer on a quad processor Intel Core i5-2500K with a frequency of 3.3 GHz (up to 3.7 GHz in Turbo mode). PC Configuration included 8 GB of RAM, hard drive capacity of 1TB with a spindle speed of 7200 rev / min and a graphic accelerator GeForce GTX 560 Ti.

In the test WorldBench 7 Windows 8 beats Windows 7 with the result of 114 points against 100. Download time for the new platform has also proved significantly less – 36.8 s vs. 56.2 s (winning about 35%). In tests, the performance when working with Web resources has outstripped predecessor, Windows 8 is 50%.

When working with digital media of Windows 7 was slightly faster, but PCWorld Labs explains the lack of optimized drivers for Windows 8. In addition, the new operating system is 8% slower when dealing with typical office tasks: editing documents, scanning for viruses, etc.

Testers believe that the final release of Windows 8 will show even better. Recall that, for Information “Network of knowledgeable sources”, Microsoft intends to finalize the new operating system in the summer, and personal computers and tablets based on it will go on sale in the fall.
