6366 HE vs 6338P: comparison
Comparison of 6366 HE and 6338P: key differences and a full specification table.
Key differences
6366 HE has more cores (16 vs 12), more threads (16 vs 12), a higher maximum clock (3.1 GHz vs 2.8 GHz) and a lower TDP (85 W vs 99 W).
At the same time, 6338P has a higher base clock (2.3 GHz vs 1.8 GHz).
Both processors match on: L3 cache (16 MB), 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.
