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.

May 27, 2010: We discovered information about new Intel desktop and server microprocessors, planned for this quarter, in a leaked Intel document. The document lists 6 new desktop processors and one server CPU.

Core i5-655K and Core i7-875K are in stock

May 19, 2010: On May 7th we posted news about pre-order of Core i5-655K and Core i7-875K microprocessors. It seems that the processors are now in stock.

Core i7-875K and Core i5-655K are available for pre-order

May 07, 2010: Core i7-875K and Core i5-655K are 32nm microprocessors with unlocked core multiplier that are expected next month. Both CPUs are based on enhanced Nehalem micro-architecture, and feature Turbo Boost and HyperThreading technologies.
