The specs for the newest and greatest ARM phone chip the A72, show that it is close to 3.5 times more powerful than ARM’s previously released Cortex-A15. It is also powerful enough to record and process 4K video at a rate of 120 frames per second.
While the specs of this 32 and 64bit capable chip look mighty impressive it is a predictor of things to come. These reference design chips are used for example by Apple in their A architecture because the company has an architectural license agreement with ARM; that has proved to be an amazing performer because Apple tweaks the design to perform incredibly fast in their devices sometimes above 50% from the reference design in some specific applications.
