Intel Corp. will release its code-named Lynnfield processors aimed at mainstream market on the 6^th of September, according to documents seen by X-bit labs. However, the high-end versions of Lynnfield chip, which will be marketed under Intel Core i7 or i5 names, will easily rival existing Core i7 both in terms of performance and in terms of price.

The first Lynnfield chiips to be unveiled will be models Core i7-870 (4 cores, 8 threads, 8MB cache, 2.93GHz clock-speed), Core i7-860 (4 cores, 8 threads, 8MB cache, 2.80GHz clock-speed) and Core i5-750 (4 cores, 4 threads, 8MB cache, 2.66GHz clock-speed) that will cost $562, $284 and $196, respectively. At present Intel Core i7-950 (4 cores, 8 threads, 8MB cache, 3.06GHz clock-speed) is priced at $562 and on October 18, 2009, Intel plans to introduce Core i7-960 chip (4 cores, 8 threads, 8MB cache, 3.2GHz clock-speed) at that price-point.

Despite of the fact that Lynnfield chips are intended to be generally more affordable than existing code-named Bloomfield (Core i7 900-series) processors, initially the price of the novelties will be similar compared to the year-old high-end products. One of the advantages the new chips have over predecessors is lower thermal design power, 95W vs. 130W.

In Q1 2010 Intel will start to roll-out the first energy-efficient chips – with 82W TDP – based on Nehalem micro-architecture: the first two chips in the new family will be Core i7-860S (4 cores, 8 threads, 8MB cache, 2.53GHz clock-speed) and Core i7-750S (4 cores, 4 threads, 8MB cache, 2.40GHz clock-speed) that will cost $337 and $259, respectively, in business quantities.

Lynnfield quad-core processor for desktops will be made using 45nm process technology and will inherit micro-architectural and architectural features from currently available Intel Core i7/Nehalem microprocessors, but will have dual-channel memory controllers. The chips will be supported by Intel 5-series chipsets and will come in LGA 1156 form-factor.
