The Core i5 is coming soon -- really soon, it appears. A sales page for the Core i5 750 went up today over at Fry's Electronics. Most folks didn't expect the i5 to make a retail appearance for about another month.
The Core i5 is a Lynnfield, featuring the new socket LGA1156 -- you can kind of think of it as a mainstream version of the new technology introduced in the higher-end Core i7 parts.
The Core i5 750 is clocked at 2.66 MHz, has 8MB L2 cache and a dual channel memory controller (we are pretty sure -- even though Fry's claims its a triple channel.) At Fry's, it is selling for a reasonable $205 -- but don't but it yet, as the accompanying P55 motherboards aren't yet available, even if they were shipping the chip.
