45nm Next Generation Intel® Core™2 Processor Family (Penryn) and Intel® Streaming SIMD Extensions 4 (Intel® SSE4)

The 45nm Next Generation Intel Core 2 processor family (Penryn) is the next generation of Intel processors based on Intel® 45nm transistor technology, a new transistor breakthrough that allows for processors with nearly twice the transistor density and drastically reduced electrical leakage. Penryn includes new instructions (Intel SSE4) and microarchitecture enhancements that will deliver superior performance and energy-efficiency while maintaining compatibility to already existing applications.

For developers, this means improved performance and energy-efficiency for existing software, and the opportunity to further optimize software to take full advantage of Intel SSE4 and the microarchitecture enhancements available in Penryn.

Check out the articles and links below to learn more about Penryn and Intel SSE4, and how they will help you create applications with superior performance and energy-efficiency.

Reply to Bruce, May 2007: Supplemental Streaming SIMD Extensions 3 and Intel(R) SSE4 will be supported in the next version of Microsoft Visual Studio* (codename Orcas). Note that Supplemental SSE3 and Intel SSE4 support will be in the form of intrinsics, as opposed to automatic code generation.

Penryn-based systems will be in production 2H '07.

When will the Microsoft Visual C++ compiler support SSE4? Visual Studio 2005 does not even support Supplemental SIMD3 instructions today. Our projct depends on the Microsoft compiler tools and so the Intel compiler is out of the question.

Where can I purchase a Penryn system?
