Intel's new 65-nm processors


By: Sander Sassen

Intel just issued a press-release yesterday that covered the re-opening of their high-volume semiconductor manufacturing facility in Chandler, Arizona, converting it to a leading-edge 300-mm, 65-nm process factory. Obviously this new factory will be producing the new 65-nm Pentium 4 processors that go by the codename 'Cedar Mill' and will be introduced in 2006. Cedar Mill Pentium 4s will be introduced in the 600-series of Intel Pentium 4 processors and hence will feature 2MB of L2-cache memory. These same processor cores will also end up in Intel's dual core processors much like todays Pentium Ds are basically two Prescott cores on a single substrate. Future Pentium D processors, codenamed 'Presler' will simply have two Cedar Mill cores which are also physically separated, unlike current Smithfield Pentium Ds.



Intel's Pentium 4 processor which was first introduced in 2000.

With the new Presler Pentium Ds Intel will introduce new model numbers as the Preslers will be dubbed the 900-series. And of course there'll be a series of Extreme Edition processors based on Presler. The new XEs will have support for HyperThreading and 1066MHz front side bus unlike the 900-series, effectively making them the fastest processors Intel has to offer. Unfortunately all of these processors and the NetBurst architecture that was introduced in 2000 will be superseded by a new architecture that Intel will launch in late 2006.

This new architecture will feature all of the good bits of both the Pentium 4 and Pentium M architecture such as the 64-bit extensions, fast front side bus, optimized power consumption and dual core support. The details are a bit sketchy still, but Intel seems dead set on keeping power consumption down to about 35-watts for mobile processors, 65-watts for desktop and 80-watts for server processors. That's a far cry from the up to 130-watts of power consumption some of Intel's current single-core processors are capable of. Mobile processors will go by the Merom codename, whereas desktop processors are said to carry the Conroe codename, no details yet on server processors though.

But before Merom debuts Intel will introduce their third generation Centrino mobile technology which will feature the dual-core Yonah processor. Just like Cedar-Mill and Presler Yonah will be a 65-nm processor but will feature something called 'SmartCache' by Sean Malony, Intel's executive vice president. In essence SmartCache is cache memory that's shared among the two processor cores and means a reduction in die-size and hence a reduction in manufacturing costs. According to Intel we'll also see a single-core Yonah to tailor to the entry-level notebook market, which could well be the new Celeron M.
