Intel's aggressive drive to 32nm has many reconsidering their purchasing plans over the next year.
All Westmere chips will feature higher performance andlower power consumption. This is made possible through the use offourth generation strained silicon and second generation high-k/metalgate technology, referring to the use of a High-k gate dielectric and ametal gate electrode.
Intel is reporting at least a 22 percent performance increase clockfor clock over their 45nm process, and there are still many steppingsto go before they go to market. Westmere also has seven new instructions, designed for accelerating encryption and decryption algorithms. All Nahalem and Westmere based processors will use DDR3 exclusively.
The first Westmere chips will be codenamed Clarkdale, featuring two 32nm logical processors paired with a graphics coreand an integrated memory controller built on a 45nm line. By using"Multi-Chip Packaging", Intel will be able to minimize their lossesfrom defective chips on a maturing manufacturing line. Arrandale is the mobile variant, with additional power saving technology for laptops.
Gulftown is the successor to the Nehalem-based Core i7 and is due in the middle of 2010. Gulftownhas six cores, but is capable of efficiently handling twelve threads atonce, thanks to its next generation Hyper-Threading. It will use theX58 chipset due to the LGA-1366 socket, but there are rumors of a newerversion coming in 2010 that will feature support for USB 3.0 and SATA6Gb/s.
DailyTech has received information that Core i5 Lynnfield and Clarksfield CPUs will be replaced by quad core Westmere variants in the middle of 2010. Intel refuses to comment on unannounced products, although they did state that "additional 32nm productswill follow in 2010".
Right now, Intel is focusing on ramping up production of Clarkdale and Arrandalefor the fourth quarter of this year. Fab D1D, Intel's manufacturingresearch factory in Hilsboro, Oregon, is already outfitted with 32nmequipment and will begin commercial production in Q4. Fab D1C and AFO(Aloha Factory Operations), in Oregon as well, will also ramp up in thefourth quarter of this year.
Intel's "Megafab", Fab 32 in Chandler, Arizona, will start 32nmproduction in early 2010, followed by Fab 11X in Rio Rancho, NewMexico. Other fabs may follow to meet demand.
Product cancellations are usually bad, but not if they are replaced with something better.
Intel's P1268 32nm development process is progressing better than expected. It is doing so well, in fact, that they are cancelling Havendale and Auburndale, the 45nm mainstream value versions of Nehalem. These were supposed to be the first mass produced chips with on die integrated graphics and an integrated memory controller.
Havendale was a dual core version of Lynnfield, itself the Core i5 mainstream version of the Nehalem Core i7. It would've used the same LGA-1156 socket as Lynnfield.
Auburndale was the mobile version of Havendale, but it had more in common with Clarkfield, the mobile variant of Lynnfield.
Having graphics on die saves motherboard manufacturers money becausethere is no longer a northbridge to buy and integrate. By loweringplatform costs, Intel wants to bring Nehalemtechnology to a new market, at a price point it previously was not ableto. This would also drive DDR3 adoption, something that DRAM manufacturers have been anticipating.
The original launch date for Havendale was towards the end of Q4, missing most of the crucial Christmas buying season. Auburndale would've been introduced in Q1 of 2010. This was to allow time for the production ramping of Lynnfield and Clarksfield into the mainstream market.
With 32nm development so advanced, Intel made the decision to pull in Clarkdale and Arrandalefrom the middle of 2010 to Q4 of 2009. They seem confident that theywill be able to ramp in time to meet demand from the critical Christmasseason.
Clarkdale is the 32nm successor to Havendale, builtusing two logic cores and a graphics core using what Intel's"Multi-Chip Packaging". The logical cores are built on a 32nm process,but the integrated memory controller and graphics core are built on a45nm process. It is capable of running four threads at once with a newgeneration of Hyper-Threading, promising increased efficiency. A server variant of Clarkdale is also to be introduced later in Q1 of 2010.
Arrandale is the mobile version of Clarkdale, also with integrated on die graphics. It will also allow switchable graphics within Windows 7 and Windows Vista, enabling the use of a higher performance GPU when plugged in. Both Clarkdale and Arrandale will use 5 series chipsets, exclusively with DDR3.
Intel's has 32nm plans with Clarkdale and Arrandale for the mainstream value segment, but enthusiasts who are looking for quad core performance at a reasonable price will look at Lynnfield and Clarksfield instead.
Lynnfield is the 45nm quad core variant of the Core i7, featuring 8MB of L3 cache and an on-die dual-channel DDR3 controller. Based on Nehalem,it is targeted at the mainstream performance segment, and uses a newLGA-1156 socket that is incompatible with the Core i7's LGA-1366 socket.
With new sockets will come new chipsets. Intel will expand their 5series of chipsets with new models for consumers and businesses. All Nahalem and Westmere based products use DDR3.
The Q57 chipset, codenamed Piketon, is targeted at businesses, while the P55 chipset, codenamed Kings Creek, is targeted at consumers.
Kings Creek will be supplemented in Q1 2010 by the P57. Bothwill have support for two external 8-lane PCIe graphics. They aresupposed to be in the Performance mainstream segment.
Neither USB 3.0, SATA 6Gb/s, PCIe 3.0, or ECC memory support were on the list of features that DailyTech received, although this may change in the future.
Clarksfield is the mobile version of Lynnfield for laptops. It uses the Capella Platform with a new chipset codenamed Ibex-Peak M. As with the current Centrino 2 platform, wireless internet will be available through an 802.11n Wi-Fi module (Puma Peak) or a WiMAX chipset (Kilmer Peak).
DailyTech has received information that Lynnfield and Clarksfield will be replaced by quad core Westmere variants in the middle of 2010. Intel refuses to comment on unannounced products, although they did state that "additional 32nm productswill follow in 2010".
The timing couldn't be better, as Windows 7 is slated to launch at around the same time. It will have many features, including improved usage of multiple cores.
