Intel Core i7-2715QE vs Intel Core i5-520E: comparison
Comparison of Intel Core i7-2715QE and Intel Core i5-520E: key differences and a full specification table.
Key differences
Intel Core i7-2715QE has more cores (4 vs 2), more threads (8 vs 4), a higher maximum clock (3 GHz vs 2.93 GHz) and a larger L3 cache (6 MB vs 3 MB).
At the same time, Intel Core i5-520E has a higher base clock (2.4 GHz vs 2.1 GHz) and a lower TDP (35 W vs 45 W).
Both processors match on: process node (32 nm), 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.
