Hi John,
The i3 only has two physical processing cores, each of which may operate with
two logical processors. Logical processors running on one physical core are no
where as speedy as two physically independent cores. Also 8-GB of RAM vs. 16-GB
of RAM certainly will affect throughput.
Regards,
Ken
