Accroding to Digitimes, Intel has decided to postpone the debut of its new mainstream desktop PC platform, Lynnfield processors (tentatively Core i5) and 5-series chipsets, from July as originally scheduled, to early September 2009.

However, Core i5 processors will be available early for retail sale in late August, while P55-based motherboards will appear even sooner in mid-August, the sources noted. Due to the global economic downturn driving down market demand, Intel expects the launch will allow more time for 4-series inventory to deplete.

Intel plans to launch three Core i5 CPUs with frequencies of 2.93GHz, 2.8GHz and 2.66GHz and priced at US$562, US$284 and US$196 in thousand-unit tray quantities. All of them will feature a TDP of 95W. The P55 chipset will be priced at US$40.
