This article confuses incomparable figures. X1 has 30% higher integer performance than A77, iso-process, A78 has 20% higher integer than A77, 5nm vs. 7nm.
X1 is in fact 22% faster than A78, iso-process. The takeaway here is that ARM now intends for the A78 to be a specialized mid-core, since it's 36%
more efficient, i.e. consumes 36% less power, at A77's peak performance, while X1 is to be the specialized performance core, or flagship core.
