Family 6, Model 26 (1Ah) = 45 nm Core i7 and Xeon (Nehalem)
Family 6, Model 30 (1Eh) = 45 nm Core i5/i7 and Xeon (Nehalem)
Family 6, Model 37 (25h) = 32 nm Core i3 (and mobile Core i5/i7) (Westmere)
Family 6, Model 42 (2Ah) = 32 nm Core i5/i7 (Sandy Bridge)
Family 6, Model 44 (2Ch) = 32 nm Core i7 and Westmere-EP
Family 6, Model 45 (2Dh) = Sandy Bridge-EP
Family 6, Model 46 (2Eh) = Nehalem-EX
Family 6, Model 47 (2Fh) = Westmere-EX/E7

But ask Intel first.
