Testing on a 2007 2.66GHz quad-core Mac Pro with a GeForce 8800GT, MovieGate MPEG-2 encode speeds went from 104fps under Leopard to 150fps under Snow Leopard, and decoding CPU usage dropped from 165 percent to 70 percent. Now, yes, that's just one app, and most users don't have four cores to play with, but it's still an eye-opening result, and we're definitely hoping it's the start of a trend.

Grand Central Dispatch may not exactly be a household name to the average Apple user, but it's certainly a hot topic among developers, who may know it better as "libdispatch," and are no doubt thrilled that Apple has now made the whole thing open source. Among other things, that means developers are now able to take full advantage of multi-core processors in Snow Leopard, which obviously has some fairly big implications for applications as soon as those developers are able to get a handle on things. Know what you're doing? Just like to get in over your head? Then you can find the complete source code and other necessary information at the read link below.

The Apple store has come back online bearing an order page for OS X version 10.6 in Starter, Home Basic, Home Premium, Pro... oh wait, it's just $29 as an upgrade from 10.5. August 28th, that's when, now go 'n get it.

While you wait for that order to ship, Apple wants you to know that Snow Leopard's Finder is more responsive, Mail loads messages twice as fast, Time Machine will complete initial backups 80 percent faster, and a 64-bit version of Safari 4 is 50 percent faster than its predecessors. There's even QuickTime X with a redesigned player that lets users view, record, trim and share video. Of course, this release also includes Grand Central Dispatch, a new way for devs to take advantage of multi-core processors as well as OpenCL support to accelerate apps with the help of that idling graphics processor. Oh, and out of the box support for Microsoft Exchange too. All in all, a worthy update, especially for the price.

P.S. Requires Intel-based Mac.
