On the iMac, duplicating the 2GB folder was about 30 percent faster, zipping the 4GB folder was 21 percent faster, and unzipping the compressed file was 43 percent faster than the new high-end Mac mini. When comparing the new Mac minis to a $1499 2.7GHz Core i5 iMac ( ) with 4GB RAM, a 7200-rpm 1TB hard drive, and AMD Radeon HD 6770M discrete graphics (we are working on Lion test results with the entry-level $1199 iMac), the results show the iMac beating the new Mac minis in every test. We ran a timedemo in Call of Duty 4 at a resolution of 1024 x 768 with 4X anti-aliasing turned on.-Macworld Lab testing by James Galbraith, Mauricio Grijalva, and William Wang. We recorded how long it took to render a scene with multiprocessors in Cinebench and ran that application’s OpenGL, frames per second test. We used Handbrake 0.95 to encode a single chapter from a DVD previously ripped to the hard drive to H.264 using the application’s Normal settings. We converted 135 minutes of AAC audio files to MP3 using iTunes’ High Quality setting. In iMovie ’11, we imported a camera archive and exported it to iTunes using the Mobile Devices setting. We duplicated a 2GB file, created a Zip archive in the Finder from the two 2GB files and then unzipped it.
All other test results in the above chart are in seconds lower results are better. Call of Duty 4 and Cinebench graphics results are based on framerate higher results are better.
