Intel Core i7-5820K vs Intel Core i7-4960X Extreme Edition: comparison
Comparison of Intel Core i7-5820K and Intel Core i7-4960X Extreme Edition: key differences and a full specification table.
Key differences
Intel Core i7-4960X Extreme Edition has a higher base clock (3.6 GHz vs 3.3 GHz), a higher maximum clock (4 GHz vs 3.6 GHz) and a lower TDP (130 W vs 140 W).
Both processors match on: core count (6), thread count (12), L3 cache (15 MB), process node (22 nm), maximum memory size (64 GB), memory channels (4), PCIe version (3).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
