Apple announced an update to the Mac mini, which includes next-generation Intel Core processors, new graphics, high-speed Thunderbolt I/O technology, and Mac OS X Lion. Apple says it has twice the processor and graphics performance of the previous version.

The outer design is pretty much the same.

“Mac mini delivers the speed and expandability that makes it perfect for the desktop, living room or office,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “With faster processors, more powerful graphics and Thunderbolt in an incredibly compact, aluminum design, the new Mac mini is more versatile than ever.”

The new Mac mini will be available in Apple’s retail stores on July 21. It’s now available through apple.com. It costs $599.

Apple also announced the Thunderbolt Display, which lets you move data between devices and your computer with what Apple calls “unprecedented speed”. It’s 27 inches and has a FaceTime camera. All the features can be found here.

The Thunderbolt Display will be available within the next 60 days through Apple.com, Apple’s Retail Stores, and through authorized resellers. It’s $999.

As previously mentioned, Apple has also updated its Macbook Air line with Thunderbolt.
