Chris is referring to the CPU performance, which is what most people are concerned about.

A 10% increase in sequential CPU performance (8 execution ports per core versus 6).

This shared arrangement reduces CPU performance by up to 35%.

The developer also needs to take into the account the lower CPU performance of older devices.

After the commoditization of memory, attention turned to optimizing CPU performance at the instruction level.

Which doesn't make it a particularly good test of CPU performance.

The days when CPU performance was a significant concern for most people are over.

Saving battery life is fine but not by cutting CPU performance.

Various other methods are used to improve CPU performance.

These are to a large extent limited by the screen size, CPU performance or memory capacity.
