After Effects is a very well-known program for video post-production, to add animations and visual effects in videos. To evaluate the performance of each CPU running this program, we ran a workload consisting of 25 compositions that applied several filters and effects to a variety of input file types such as PSD (Photoshop), AI (Illustrator), EPS, and TIF. After each filter was applied, the composition was rendered to an uncompressed AVI file of the same resolution as the input files. The results below are the time each CPU took to finish the whole batch, given in seconds, so the lower the number the better.

On After Effects CS4 Core i5-750 was 30.99% faster than Core 2 Quad Q6600 and 47.82% faster than Core 2 Duo E8400.

Core i7-870 was 6.14% faster than Core i7-920, 16.20% faster than Core 2 Extreme QX 9770, 21.05% faster than Core i5-750, 45.52% faster than Core 2 Quad Q6600 and 58.80% faster than Core 2 Duo E8400.

Core i7-920 was 15.88% faster than Core i5-750, and they run at the same clock rate.

Core i7-965 was the fastest CPU here, being 7.43% faster than Core i7-870 and 26.92% faster than Core i5-750.
