Intel Core i5-750 vs Intel Core i7-860: comparison
Comparison of Intel Core i5-750 and Intel Core i7-860: key differences and a full specification table.
Key differences
Intel Core i7-860 has more threads (8 vs 4), a higher base clock (2.8 GHz vs 2.66 GHz) and a higher maximum clock (3.46 GHz vs 3.2 GHz).
Both processors match on: core count (4), L3 cache (8 MB), TDP (95 W), process node (45 nm), maximum memory size (16 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.
