CPU

Answer

Indicative content:

Specification 2 has a higher clock speed and therefore will be able to deal with a greater number of instructions / cycles per second with the effect that processing will be faster than for Specification1.
Because of the higher clock speed the CPU in Specification 2 will use more energy and create more heat than the CPU in Specification 1.

The CPU cache memories and the bandwidths are the same.

Specification 1 has more RAM / a larger memory and will therefore be able to handle more programs and operations at the same time. The larger memory will reduce the extent of swapping with virtual memory / secondary storage which will go some way to offset the benefit provided by the greater clock speed of Specification 2.?
