Compare Processor Numbers
Is faster always better? Yes, but it's not always what you should buy.
So as you evaluate the performance of the components below, don't analyze them in isolation from each other, but consider them interdependent partners that make up your projected system. And, keep in mind that your future needs—adding software from a growing family or a growing business—might be different later.

Looking for an Intel Core i5 desktop PC?
◊ Intel® Turbo Boost Technology requires a PC with a processor with Intel Turbo Boost Technology capability. Intel Turbo Boost Technology performance varies depending on hardware, software, and overall system configuration. Check with your PC manufacturer on whether your system delivers Intel Turbo Boost Technology. See www.intel.com/technology/turboboost/ for more information.
Δ Intel® Core™ i5-750 processor with a 2.66 GHz base frequency reaches a maximum Turbo frequency of 3.20 GHz. See www.intel.com/technology/turboboost/ for more information.
‡1 PCMark* Vantage is a collection of various single- and multi-threaded CPU, Graphics, and HDD test sets with the focus on Windows* Vista application tests. Tests have been selected to represent a subset of the individual Windows Vista Consumer Scenarios.
‡2 As measured based on VirtualDub* 1.7.2 with DivX* 6.7 codec comparing Intel® Core™ i5-750 processor based laptops to previous generation Intel® Core™2 Quad processor Q9400. Actual performance may vary. See www.intel.com/go/consumerbenchmarks/ for important additional information.
‡3 As measured based on Adobe* Album Starter where the workload consists of running auto smart-fix on 50 6MP photos that total about 118MB in size.
‡4 Apple iTunes* 7.4.3 is a digital media application that can be used to manage digital music such as converting from one digital audio format to another. In this case, Apple iTunes is used to convert 61 minutes, 24 seconds of music from WAV to MP3 format with a bit rate of 160Kbps for listening on your iPod*.
‡5 3DMark* Vantage CPU test covers the two most common CPU-side tasks: Physics simulation and artificial intelligence. Measurements compared for the Intel® Core™ i7-950 processor and the Intel® Core™2 Quad processor Q9650.
‡6 Intel® High Definition Experience and Performance Ratings Test 2009 (Intel® HDXPRT 2009) is a benchmark that runs consumer digital media applications on a PC, measures performance, and provides an indicator of the expected quality of video playback. Intel® HDXPRT 2009 automatically runs tests using commercially available applications from the following usage categories: music encoding, photo and video editing, and High Definition video playback. Test compared the Intel® Core™ i7-920XM processor and the Intel® Core™2 Extreme Processor QX9300. Actual performance may vary. See www.intel.com/performance/desktop/extreme/ for more information. Results may vary depending on many variables including the processor, memory, disk drive, graphics card and operating system on the test system.

‡7 As measured based on VirtualDub* 1.7.2 with DivX* 6.7 codec comparing Intel® Core™ i5-750 processor based laptops to Intel® Pentium® Processor E5300. Actual performance may vary. See http://www.intel.com/performance for important additional information.
‡8 As measured based on Adobe Photoshop Lightroom* 2.3, a photography application that lets you manage, adjust, and present a large amount of photographs. For this scenario Lightroom 2.3 is used to resize 125 ten-megapixel and 75 six-megapixel JPEG photos at 480x360 resolution for posting to Facebook* or viewing on portable devices such as an iPhone*. The photos are also used to create a personal HTML web gallery that can be published online. Extrapolation used to calculate the number of images you can prepare in 1 minute for upload to Facebook.
‡9 As measured based on Apple iTunes* 8.2, a digital media application that can be used to manage digital music such as converting from one digital audio format to another. In this case, Apple iTunes is used to convert 61 minutes, 24 seconds of music from WAV to MP3 format with a bit rate of 160Kbps for listening on your iPod*. Extrapolation used to calculate the number of songs you can convert in 5 minutes.
