4256 EE vs 3250 HE: comparison
Comparison of 4256 EE and 3250 HE: key differences and a full specification table.
Key differences
4256 EE has a larger L3 cache (8 MB vs 4 MB) and a lower TDP (35 W vs 45 W).
At the same time, 3250 HE has a higher base clock (2.5 GHz vs 1.6 GHz) and a higher maximum clock (3.5 GHz vs 2.8 GHz).
Both processors match on: process node (32 nm).
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.
