Intel Core i7-620M vs Intel Core i3-330M: comparison
Comparison of Intel Core i7-620M and Intel Core i3-330M: key differences and a full specification table.
Key differences
Intel Core i7-620M has a higher base clock (2.66 GHz vs 2.13 GHz), a larger L3 cache (4 MB vs 3 MB) and a higher maximum integrated graphics clock (766 MHz vs 667 MHz).
Both processors match on: core count (2), thread count (4), TDP (35 W), process node (32 nm), maximum memory size (8 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.
