> [Intel] QuickSync, now in its third generation with the Haswell architecture, provides dramatic speed increases for H.264 encoding and decoding (and some flavors of MPEG-2).

> This also creates some interesting disparities in performance. The newest Intel Xeon chips, like those used in the powerhouse Mac Pro, don’t support QuickSync. Because Xeons are primarily intended for use in servers, Intel doesn’t deem it necessary. This means that, in some cases, a fast Macbook Pro, Macbook Air, or iMac will outperform even a loaded Mac Pro.
