An early build of Windows 11 was slower than the current version of the operating system from Microsoft.
Media experts have studied an early ISO-image with Windows 11, the release of which should take place at the end of June. Journalists were interested in how the performance of the new operating system has changed and how much faster or slower than Windows 10. For testing, the authors ran synthetic tests of both operating systems on two computers – a Dell XPS 13 9300 with a 10th-generation Intel i7-1065G7 processor and a Lenovo IdeaPad Slim 7 with an AMD Ryzen 7 4800U chip.
The Geekbench test showed that the performance of Windows 10 and Windows 11 is almost similar, PCMark 10 showed a slight superiority of Windows 10 – especially on the Dell XPS 13 9300 computer. In the Cinebench R23 test, single-threaded results were fairly stable on both platforms, but in multi-threaded mode, the old OS beat the new one. The 3DMark Night Raid benchmark showed parity of the operating systems or slight superiority of Windows 10.
The only benchmark that put the new operating system ahead of the current one was Speedometer 2.0, which checks the speed of web applications. Here Windows 11 scored over 150 points, while Windows 10 on all computers barely made it 130 points.
Journalists concluded that in terms of almost all synthetic tests, the current operating system was faster than the new one. Problems with the speed of Windows 11 is associated with the “crude” build and some compatibility issues that will be fixed after the product release.
Windows 11 is expected to be announced on June 24. Users of Windows 10, 8.1 and 7 will receive the update for free.
