The Core i7-6950X Extreme Edition is a 64-bit deca-core top-of-the-line MPU introduced by Intel for the enthusiasts market in mid-2016. The i7-6950X replaced the i7-5960X as Intel's flagship microprocessor based on Broadwell microarchitecture - also becoming the first consumer-class deca-core microprocessor.
