Apple Keynote 2009 WWDC New Snow Leopard Technologies

WWDC: Apple Announces New Technologies For Snow Leopard

Here we are at WWDC, in the midst of hot Apple news, and now we're onto the nitty gritty: the technology itself.

Bertrand Serlet has the honor of introducing Snow Leopard's new technologies, which revolve around taking advantage of the power of your processor. They include:

  • 64-bit Mode: Using 64-bit mode takes advantage of the mass of memory, hitting a limit only at 16 billion gigs rather than four; this means the processor can move much faster in 64-bit mode, and all of the major applications will run in 64-bit mode. Thus, twice as fast!
  • Grand Central Dispatch: GCD will control the threads of multicore processors. Basically, when you're running an application, the threads that are produced stay up when the same app is idle; GCD redirects those threads so that they're not being used up when an application is idle. Hence, another way to make Snow Leopard faster!
  • OpenCL: OpenCL (the "C" stands for computing) utilizes the raw power of graphics cards beyond just graphics; the best part of OpenCL is that it will actually have an open standard and many top tech companies are already participating.
