Intel has brought forward the mass production of its 32nm processor codenamed Clarkdale to the fourth quarter of 2009, from the originally planned first quarter of 2010, according to Digitimes.

The 32nm Clarkdale is expected to account for 10% of Intel’s total OEM desktop CPU shipments, while 45nm Core i7 processors will take up 1%, Lynnfield-based processor 2%, Core 2 Quad processors 9%, Core 2 Duo E8000/E7000 series processors 35%, Pentium E5000/E6000 series 31%, Celeron E3000 and Atom series together 8%, and 65nm Pentium E2000 and Celeron 400 together 4%.

The proportion of Clarkdale-based processors will rise to 20% in Q1 next year, while 45nm CPUs will account for 78%, and 65nm Celeron 400 series will drop to 2%.
