eWeek - Intel is rolling out 16 new 45-nanometer processors Monday Nov. 12 code-named Penryn. The microarchitecture will remain the same, however there is a die shrink and will include 12 quad-core Xeon 5400 series processors, previously code-named Harpertown, and three dual-core Xeon 5200 series chips, formally called Wolfdale DP. The final processor is a Core 2 Extreme QX9650 for high-end and gaming. The new processors will use its Hafnium-based processor technology that will reduce power leakage—the electricity wasted while the transistors are idle—which will improve the power performance. The 45-nanometer will allow Intel to save on manufacturing costs since it can now squeeze more Penryn processors onto a 300 millimeter wafer than it could with 65-nanometers processors.
