Batches make little diff ....

To many variables per chip nowadays.

Law of science are reflected in these chips.......it's all a give and take situation.

some chips have "balanced" cores, those will never be good for a validation.....Some chips are rather "unbalanced" those will never be great at multithreaded.......

Some chips have killer core speed......enter your first chip.....but at a price....weak NB.....Then there is the opposite spectrum.....strong NB.....but then weak Core speed.

Then there is another factor that throws a curveball.....how strong the mem controller is.....think becasue your chips has good NB it has a strong IMC?

Wrong.....thats another totally diff part of spectrum.

Best you can hope for is 2 out of 4, rare to have 3 out of 4.

For benching the best you can do is know your hardware and use whatever chips suits a particular benchmark best
