Core i7-4790K vs Core i7-7700K
The Core i7-4790K and Core i7-7700K monothread performance are slightly different furthermore their multithread performance are slightly different. These two models were released just two years apart which doesn't explain their performance difference so we should check if they belong to the same range.
