Synthetic CPU and Final Thoughts

Super Pi Mod 1.5 Source: SuperPI

SuperPI calculates the number PI to 1 Million digits in this raw number crunching benchmark. The benchmark is fairly diverse and allows the user to change the number of digits of PI that can be calculated from 16 Thousand to 32 Million. The benchmark, which uses 19 iterations in the test, is set 1 Million digits.

Lower calculation times are better. SuperPi is not multi-threaded.

With other components like the videocard and hard drive no longer in the equation, the single-threaded performance levels between Windows Vista and Windows 7 again even.

Performance Benefit from Upgrading to Windows 7? Yes.

Microsoft has focused it performance improvements in areas where they were needed the most. While most computers with CPUs from the past five years or so are able to run multiple lightweight applications like a web browser or email client while a music player is running in the background. Similarly, dedicating a CPU to a single intensive application (especially when it's single threaded) tends to reach its maximum potential, regardless of operating system.

The real problem comes when there's a combination of an intensive multi-threaded task and other applications running simultaneously. You're compressing a multi-gigabyte ISO file that could take several minutes to complete, and you suddenly find that your system becomes so sluggish that you can no longer open up a web browser, your music player starts skipping and even basic tasks like opening up Internet Explorer are taking longer than they should.

Windows 7 makes a significant improvement over Windows Vista in these scenarios, with large performance gains demonstrated for nearly every class of processor.

In fact, dual-core processors actually stand to gain the most in this scenario as Windows 7 is much better at balancing workload between two cores than Vista's conservative approach that often left one CPU core at full usage and the other under-utilized when running background processes. If you own an older Intel Core 2 Duo or AMD Athlon processor and are noticing sluggish CPU performance, upgrading to Windows 7 can make a significant impact on your computing experience just in the way it handles CPU performance.

Quad-core owners will also a noticeable improvement in performance, particularly when it comes to encoding media. If you moved to a quad-core processor in order to edit and encode video, then Microsoft Windows 7 can make a significant improvement in the kind of performance you can get out of your PC.

If you're the type of person who was unfazed by Windows 7's fancy new features and slick interface, these performance benchmarks might make a more convincing case for upgrading. There's a lot to like in Windows 7, and that includes better CPU performance.
