Intel Corp. plans to release its next-generation performance-mainstream microprocessors code-named Lynnfield in September this year, which is considerably later compared to the original schedule. The delay is believed to be a result of the global financial slump.

Intel originally planned to release its Core i5 processors (Lynnfield) in July ’09 and ramp up its production by back-to-school season. However, slow demand towards current-generation microprocessors and core-logic sets forced Intel to reconsider its plans and release the new chips only in early September, 2009, reports DigiTimes web-site.

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 smaller caches and dual-channel memory controllers. The chips will be supported by Intel 5-series chipsets and will come in LGA 1156 form-factor.

Intel plans to initially release three Core i5 central processing units with clock-speeds of 2.93GHz, 2.8GHz and 2.66GHz and priced at $562, $284 and $196 in business quantities. All of them will feature a TDP of 95W.

Intel traditionally does not comment on unreleased products.
