CPU Comparison

Intel Core i7-960 vs Intel Core i7-975

A side-by-side comparison of specs, performance and value. The Intel Core i7-960, released in October 2009, served as the final quad-core Bloomfield chip before the platform transitioned to hexa-core Gulftown. Operating at a brisk 3.2GHz base clock with a 3.46GHz turbo, it offered the highest stock frequencies of the standard quad-core lineup. This four-core, eight-thread processor was designed for users who wanted maximum out-of-the-box performance without paying the Extreme Edition premium. It maintained the 45nm process, 8MB L3 cache, and 130W TDP characteristic of the Bloomfield family. While it couldn't match the multi-threaded prowess of the upcoming six-core chips, its high clock speeds made it excellent for single-threaded gaming workloads. The i7-960 marked the end of an era, representing the peak of Intel's quad-core enthusiast strategy before core counts began to scale dramatically in the consumer space.
