Windows 8 is faster than Windows 7
The most obvious of Windows 8 is definitely the Metro interface, but many changes compared to Windows 7 are not visible to the naked eye. Microsoft, for example, has stated that Windows 8 is faster than Windows 7 at boot time. PCWorld has done some tests to check the veracity of this statement.
The test setup requires a PC equipped with an Intel Core i5-2500K at 3.3 GHz, 8 GB of RAM DDR3 at 1,333 MHz, a 1 TB hard drive at 7,200 rpm and a video card NVIDIA GeForce GTX 560 Ti. PCWorld has used its benchmark WorldBench 7 which allows to evaluate the overall performance of the system, assigning a percentage value to the individual tests that make up the suite (Office Productivity, Content Creation, Web Performance, Storage Performance and Startup Time).
The published results show that the Windows 8 Consumer Preview is 14% faster than Windows 7 with all of the tests included in WorldBench 7. The start time of the PC with Windows 8 is 36.8 seconds, about 35% lower than that of Windows 7 (56.2 seconds). This number is even more interesting when you consider that the test ends only when you receive a text file. In Windows 8 must be started before the desktop interface to run the file located in your startup folder. The boot time will be even lower if you replace the hard disk with an SSD.
To measure performance in rendering web pages is WebVizBench test was used. Again here win the Windows 8: Internet Explorer 10 achieves 28.6 frames per second, about 50% more than Internet Explorer 9 and thank to the optimizations of the browser and hardware acceleration.
Windows 8 is positioned behind Windows 7 in content creation (audio/video encoding and image editing), although for a few seconds. This certainly depends on the video driver, not yet updated for the new operating system. Finally, in testing PCMark 7, Windows 8 is about 8% slower than Windows 7, but this result may change with the new version of the benchmark from Futuremark released.
