Digital Home Performance: Previous Generation Intel® Core™2 Quad Processor

1. HD content playback capability is measured for this platform using CPU Utilization (objective score in %). The playback quality is measured over the first 100 seconds of this movie and several chapters. The lower the CPU utilization score, the better.

2. Pegasys TMPEGEnc* 4.4 allows you to take almost any video file and encode it to your desired file format including DivX*, AVI, QuickTime*, MPEG 4-ISO, H.264, DVD-Video, DVD-VR, HDV camcorder, Blu-ray* disc, and much more. The input file for this workload is a 1min 16sec, 29.97fps, 1440x1080 video clip with VBR encoding and a total size of about 1.12GB. The ouput is an HDV format MPEG file with 1440x1080 resolution, 29.97fps, and 25000Kb/s CBR encoding. The extrapolation is used to calculate the number of videos you can encode in 1 hour.

3. The Intel® Digital Home Capabilities Assessment Tool (Intel® DHCAT) is an extensible and experiential framework to assess user-centric digital home platform capabilities, reflecting many current and emerging usages. DivX* Pro Version 6.6 was used to convert Hi-Def video to DivX* format for Hi-Def video archival (1 hour). On2* VP7 was used to convert standard-Def video into flash format for viewing on YouTube* (1 hour). Photo processing application based on Dcraw Library Rev. 1.332 was used to convert raw pictures to JPEG format for photo compression (15 minutes).

4. VirtualDub* is a video capture/processing utility. It is streamlined for fast linear operations over video and allows users to batch process multiple tasks on multiple video files. DivX* is a format for digital video. The workload for VirtualDub is a 66.2MB 110sec MPEG2 video file in 720x480 resolution at 5Mbps. It is converted to DivX format with 720x480 resolution with a total size of ~10.3MB. Extrapolation is used to calculate the number of videos you can convert in 30 minutes.

5. Apple iTunes* 7.6.2 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*. Extrapolation is used to calculate the number of 4-minute songs you can convert in 5 minutes.

6. Adobe Photoshop Lightroom* 1.1 is a photography application that lets you manage, adjust, and present a large amount of photographs. For this scenario, Adobe Photoshop Lightroom 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 Apple iPhone*. The photos are also used to create a personal HTML web gallery that can be published online. Extrapolation is used to calculate the number of images you can prepare in one minute for upload to Facebook*.

7. HQV evaluates the image quality for Plasma, LCD, RPTV, or Front Projector HDTV.

8. HD-HQV evaluates the picture quality of various high definition products, such as your HDTV, monitor, video scaler, HD-DVD player, Blu-ray* player, projector, or AV receiver.

9. Cinebench* 10 is a test suite that assesses your computer's 3D-image rendering capabilities.

10. PCMark Vantage* measures hardware performance for PCs running 32 and 64 bit versions of Microsoft Windows Vista*. Its benchmark result is a combination of the various test suites by PCMark Vantage to evaluate different usage scenarios.

11. Warning: Altering clock frequency and/or voltage may: (i) reduce system stability and useful life of the system, processor, and other system components; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond its specifications. Intel has not tested, and does not warranty, the operation of other system components beyond their industry standard specifications. Intel assumes no responsibility that the processor and other system components, including if used with altered clock frequencies and/or voltages, will be fit for any particular purpose.

12. Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel® products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, visit www.intel.com/content/www/us/en/benchmarks/resources-benchmark-limitations.html.

13. Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.
