The Intel Core 2 Duo series is about to embark on a die shrink, from 65nm to 45nm. The new Core 2 Duo's, codenamed "Penryn", will have a slew of new features. The Penryn's will support a new set of SSE instructions, have higher clock speeds while maintaining the same power draw, and have a larger L2 Cache. The dual core Penryn will have 410 million transistors, and the quad core Penryn will have 820 million. All of the Penryn's will be on a 300mm package. Like with the current generation quad core offerings, the quad core Penryn's will have two dual core processors on one package. The Penryn series will have the same power requirements as the Conroe, which translates to 35W laptop chips, 65W dual-core desktop chips, and 80W quad-core desktop chips. Intel has successfully tested the Penryn's on several operating systems for stability, and we should see something commercially available around Q2 2007.
