I am making some guesses here. I assume you are asking about:
ARK | Intel® Atom™ Processor Z3736F (2M Cache, up to 2.16 GHz)
ARK | Intel® Celeron® Processor N2820 (1M Cache, up to 2.39 GHz), which is included with the ARK | Intel® NUC Kit DN2820FYKH
If correct, then this is the comparison: ARK | Compare Intel® Products
