Windows 7 will give boost to PC hardware.
Windows 7 will be more than just a better interface. Under-the-hood changes will allow chips from Intel, Nvidia, and Advanced Micro Devices to ratchet up Windows 7 performance above previous Microsoft operating systems.
Microsoft on Wednesday said it has finalized the code for Windows 7, set to ship with new PCs starting October 22. Improvements will include how Windows handles multitasking, graphics acceleration, and solid-state drives
Microsoft is working closely with Intel, whose chips will power the vast majority of PCs running Windows 7. A July 22 post from Joakim Lialias, Intel Alliance Manager for Microsoft, described how Microsoft and Intel "saw unique opportunities to optimize Windows 7 for Intel processor technology" in the areas of performance, power management, and graphics.
In his blog, Lialias focused on improvements to multitasking based on "SMT Parking," which provides additional support to the Windows 7 scheduler for Intel Hyper-threading Technology. With Hyper-threading, the operating system sees a single processor core as two cores. For example, a quad-core system would be seen as having eight cores, thus potentially improving multitasking--or doing tasks (threads) simultaneously.
Hyper-threading is back in vogue at Intel after being pulled from Intel Core 2 chips (it debuted in the Pentium 4 processor). Nehalem Core "i" series processors use Hyper-threading, as do Atom chips. Intel, in fact, now includes Hyper-threading as part of a chip's core specifications. The Core i7-975 processor, for example, is listed as "4 Cores, 8 Threads."
