Intel Core i7-4820K vs Intel Core i7-4960X Extreme Edition: comparison
Comparison of Intel Core i7-4820K and Intel Core i7-4960X Extreme Edition: key differences and a full specification table.
Key differences
Intel Core i7-4820K has a higher base clock (3.7 GHz vs 3.6 GHz).
At the same time, Intel Core i7-4960X Extreme Edition has more cores (6 vs 4), more threads (12 vs 8), a higher maximum clock (4 GHz vs 3.9 GHz) and a larger L3 cache (15 MB vs 10 MB).
Both processors match on: TDP (130 W), 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.
