Windows 7 and Vista start, memory, power consumption comprehensive comparison

At the WinHEC 2008 conference a few days ago, Microsoft continued to introduce Windows 7, the first project is to compare the startup time with Vista.

Watch the video first:

On a computer with the same configuration, Windows 7 starts up about 5 seconds faster than Vista.

Microsoft said that the 5 second speed is thanks to the following improvements:

1, improve device initialization parallelism

2, reduce disk data read

3, change the startup sound

4, a lot of other details optimization and enhancement

In addition, Microsoft also showed memory consumption. A large number of windows are opened on the two systems. After a certain number of Vistas, the error is reported. The memory usage under Windows 7 is not directly related to the number of windows. Therefore, as the number of windows increases, the memory is not consumed sharply. Still running smoothly.

With the enhancement of the operating system and its functions, the battery life of laptops can not be ignored. Microsoft took out two identical notebooks and played DVD videos at the same time. As a result, Windows 7 persisted for more than an hour longer than Vista, and Microsoft said that Windows 7 can bring at least 11% more battery life, about 20. minute. In addition, Microsoft has provided some new gadgets to analyze laptop battery consumption and correct errors that affect battery life.

Other display projects include: Windows 7 interaction with Nokia N95 8GB, Logitech camera, Bluetooth 2.1 device; Atom 330 dual-core processor, 1GB RAM, 16GB The solid state drive Eee PC runs Windows 7; a set of Core i7 with Windows 7 and GeForce GTX 280 SLI platform runs Crysis and so on.

Steven Sinofsky and Jon DeVaan's presentations total about 1 hour and 18 minutes. Interested parties can click here to watch (750Kbps).
