An Intel spokesperson recently stated that Microsoft Windows 7 offers “improved performance and stability” compared to Vista and the veteran, yet aging XP operating system.
According to Shiv Kaushik, Intel and Microsoft “closely cooperated” on optimizing both energy efficiency and performance for Windows 7.
“Our joint objective was to examine the combination of technology and features inherent in Intel processors and complement the capabilities on the software side,” said Kaushik.
“So, we focused on two primary areas to ensure energy efficiency: timer coalescing and core parking. The former improves efficiency by automatically extending idle periods and the latter loads tasks onto a specific core, allowing the others to idle when possible.”
He noted that Nehalem microarchitecture “enhanced” hyper-threading, while Windows 7 “optimized” the technology with “intelligent” scheduler decisions.
“In short, our collaboration resulted in the optimal performance of multi-threaded applications and real-world multi-tasking scenarios,” concluded Kaushik.
Intel spokesperson Uday Marty added that the two industry heavyweights had collaborated to facilitate “top” PC performance by minimizing resume, shutdown, boot and startup time.
He emphasized that Windows 7 was “much more efficient” in terms of its memory allocation than Vista.
