Intel Core i5-3450 vs Intel Core i7-3770K: comparison
Comparison of Intel Core i5-3450 and Intel Core i7-3770K: key differences and a full specification table.
Key differences
Intel Core i7-3770K has more threads (8 vs 4), a higher base clock (3.5 GHz vs 3.1 GHz), a higher maximum clock (3.9 GHz vs 3.5 GHz) and a larger L3 cache (8 MB vs 6 MB).
Both processors match on: core count (4), TDP (77 W), process node (22 nm), maximum memory size (32 GB), memory channels (2), 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.
