Question

Consider the following two scenarios for a 150M trasistor chip. A: it contains 3 large homogeneous cores, each having 50M transistors. B: it contains 1 large core having 50M transistors and 10 small homogeneous cores having 10M transistors each. Suppose each large core has throughput 1 and small core throughput is computed using Pollack's rule: (10/50)^0.5=0.45. What is the total throughput of A and B?

Answer 1

As given in the question the throughput of large core is 1 and the throughput of the smaller core can be derived from the given formula in the question , as given in the question A contains three large core so the total output of A is 3 because A has three large cores and each core has throughput of 1 so we get the total throughput as 3. The total throughput of B is 1 + 10x(0.45) because it is given in the question that B has one large core and 10 small core so we get the total throughput as 5.5. from the drive throughput we can say that the B as more throughput then A.
