Intel Core i7-660LM vs Intel Core i3-330UM: comparison
Comparison of Intel Core i7-660LM and Intel Core i3-330UM: key differences and a full specification table.
Key differences
Intel Core i7-660LM has a higher base clock (2.26 GHz vs 1.2 GHz), a larger L3 cache (4 MB vs 3 MB) and a higher maximum integrated graphics clock (566 MHz vs 500 MHz).
At the same time, Intel Core i3-330UM has a lower TDP (18 W vs 25 W).
Both processors match on: core count (2), thread count (4), 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.
