Intel Core i7-875K - BV80605001905AM / BX80605I7875K

CPU » Intel » Core i7 families » Core i7 » i7-875K

Specifications

Core i5-875K is one of the first not overly expensive Intel non-Extreme microprocessors with unlocked clock multiplier. According to preliminary specifications, unlocked multiplier is the only difference of this CPU from Core i7-870, and in all other aspects they are nearly identical: 45nm Lynnfield core, quad-core design, 2.93 GHz core frequency, shared 8 MB level 3 cache, and the latest Intel technologies including HyperThreading and Turbo Boost. It is expected that the Core i7-875K part will be launched together with Core i5-655K in the first half of June 2010. Official price for the i7-875K is not known yet. If the only leaked pre-order price is correct, then official price will be in the range $340 - $370.

The box has updated design with gray outline, and "Unlocked" word on the gray background on the front of the box. The box does not come with the fan/heatsink, and, therefore, is very light. It is also smaller (narrower) than other Core i7 boxed processors. Inside of the box you'll find only the CPU and installation instructions, and a lot of unused space.
