Intel Core i7-2700K vs Intel Core i5-2320: comparison
Comparison of Intel Core i7-2700K and Intel Core i5-2320: key differences and a full specification table.
Key differences
Intel Core i7-2700K has more threads (8 vs 4), a higher base clock (3.5 GHz vs 3 GHz), a higher maximum clock (3.9 GHz vs 3.3 GHz) and a larger L3 cache (8 MB vs 6 MB).
Both processors match on: core count (4), TDP (95 W), process node (32 nm), maximum memory size (32 GB), memory channels (2), PCIe version (2).
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.
