Due for release sometime next year, Snow Leopard will contain no new visible features, but major performance and core feature enhancements. Among these are vastly improved support for multi-core processors with a new technology code-named “Grand Central,” making it easy for developers to create programs that take full advantage of the power of multi-core Macs. Snow Leopard further extends support for modern hardware with Open Computing Language (OpenCL), which lets any application tap into the gigaflops of GPU computing power previously available only to graphics applications. OpenCL is based on the C programming language and has been proposed as an open standard. Snow Leopard also raises the software limit on system memory up to a theoretical 16TB of RAM.

Snow Leopard will also include native support for Microsoft Exchange 2007 in Mail, iCal and Address Book.
