Mac OS X Snow Leopard Version 10.6.3

The world’s most advanced operating system. finely tuned.

64-bit

64-bit computing used to be the province of scientists and engineers, but now this generational shift in computing gives all users the tools to apply the power of 64-bit to speed up everything from everyday applications to the most demanding scientific computations. Although Mac OS X is already 64-bit capable in many ways, Snow Leopard takes the next big step by rewriting nearly all system applications in 64-bit code¹ and by enabling the Mac to address massive amounts of memory. Now Mac OS X is faster, more secure, and completely ready for the future.

NVIDIA AMD intel

Familiar, C-based language with industry support.
OpenCL stands for Open Computing Language. It’s a C-based programming language with a structure that will be familiar to programmers, who can simply use Xcode developer tools to adapt their programs to work with OpenCL. They don’t have to completely rewrite applications to use OpenCL. They need only rewrite the most performance-intensive parts of their application in OpenCL C. The vast majority of application code can be left unchanged. Best of all, OpenCL is an open standard that’s supported by the biggest names in the industry, including AMD, Intel, and NVIDIA.

OpenCL

With graphics processors surpassing speeds of a trillion operations per second, they’re capable of considerably more than just drawing pictures. OpenCL in Snow Leopard is a technology that makes it possible for developers to tap the vast gigaflops of computing power currently in the graphics processor and use it for any application.

QuickTimeX

Snow Leopard introduces QuickTime X, a major leap forward that advances modern media and Internet standards. QuickTime X includes a brand-new player application, offers optimized support for modern codecs, and delivers more efficient media playback, making it ideal for any application that needs to play media content.

Grand Central Dispatch

More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central Dispatch takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central Dispatch also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.
