Early Intel LGA-1156 Quad-Core SKUs Surface
Intel recently detailed its strategy with the Core brand, and its various brand-modifiers (namely i3, i5, i7, and i9). The move to give some LGA-1156 processors the Core i7 modifier, based on the performance level they offer, particularly sparked off several debates about if the move actually benefits the consumers as much as it does to Intel. Back then, Intel did not divulge much about a number scheme that characterizes LGA-1156 Core i7 processors from their LGA-1366 counterparts. Fresh information suggests that Intel may have one such number-scheme in place that will demystify its lineup.

The LGA-1156 socket lineup will be spearheaded by quad-core desktop chips that will start selling from September 8, tentatively. These consist of a 2.66 GHz part, a 2.80 GHz part, and another 2.93 GHz one. Sources revealed much earlier that these could be priced US $194, $284, and $562, respectively. Among these three, the 2.66 GHz part lacks HyperThreading technology in its feature-set, and hence, will be placed in the Core i5 series. To further clarify the lineup, the following model numbers have been suggested:

I don't understand how they come up with these chips and charge what they do for them. Same stuff with other lines also.

These consist of a 2.66 GHz part, a 2.80 GHz part, and another 2.93 GHz

I mean if they were 2.6ghz, 3.6ghz, 4.2ghz or something like to make it worth while to buy the next one up, but a .14ghz increase ?

I am sure it's all about how they bin these durning production.
