The Core i7-5960X Extreme Edition is a 64-bit octa-core top-of-the-line MPU introduced by Intel for the enthusiasts market in mid-2014. The i7-5960X replaces the i7-4960X, as Intel's flagship microprocessor based on Haswell microarchitecture. This chip operates at 3 GHz with turbo frequency of up to 3.5 GHz for a single core. The i7-5960X supports up to 64 GiB of memory (DDR4). This processor was eventually replaced by i7-6950X, a Broadwell-based model.
