Digitimes reports extensively on the latest family of Intel CPU cores to be roadmapped.
"Intel will begin producing its next-generation Penryn family of processors in the second half of 2007. These new processors benefit from enhancements to the Intel Core microarchitecture and also Intel's 45nm Hi-k process technology with its hafnium-based high-K + metal gate transistor design, which results in higher performance and more energy-efficient processors.
Intel has more than 15 45nm Hi-k product designs in various stages of development, and will have two 45nm manufacturing fabs in production by the end of the year, with a total of four in production by the second half of 2008. Intel plans to deliver tens of millions of these processors.
Six Penryn family processors, including dual- and quad-core desktop processors and a dual-core mobile processor are planned for release under the Intel Core processor brand name as well as new dual- and quad-core server processors under the Intel Xeon processor brand. A processor for higher-end server multiprocessing systems is also under development.
45nm next-generation Intel Core 2 quad-core processors will have 820 million transistors. The dual-core version has a die size of 107mm squared, which is 25 percent smaller than Intel's current 65nm products and operate at the same or lower power than Intel's current dual core processors.
The mobile Penryn processor has a new advanced power management state called Deep Power Down Technology that significantly reduces the power of the processor during idle periods such that internal transistor power leakage is no longer a factor. This helps extend battery life in notebbooks.
For the mobile Penryn processor, Intel has enhanced the Intel Dynamic Acceleration Technology available in current Intel Core 2 processors. This feature uses the power headroom freed up when a core is made inactive to boost the performance of another still active core.
Penryn includes Intel Streaming SIMD Extensions 4 (SSE4) instructions, the largest unique instruction set addition since the original SSE Instruction Set Architecture (ISA). This extends the Intel 64 instruction set architecture to expand the performance and capabilities of the Intel Architecture.
After Penryn and the 45nm Hi-k silicon technology introduction comes Intel's next-generation microarchitecture (Nehalem) slated for initial production in 2008."
