Reply #25: Core i3 & Core 2 < Core i5 < Core i7 & Xeon

[pokerfan]

Core i5 is a brand name used by Intel for several upcoming processors. It is positioned between the mid-range Core i3 and Core 2 and the high-end Core i7 and Xeon brands.

As of September 7, 2009, there is only one Core i5 processor: The Core i5 750,<1> which is a 2.66 GHz quad-core processor with Hyper-threading disabled. This appears to be a case of crippleware, as the other two speed grades of LGA 1156 processors introduced at the same time include Hyper-threading, but are Core i7 processors.
