Obviously your weird inability to understand that people prioritize things other than single core performance in a device with a wide variety of use cases aside, this is a simplistic view of performance in real world devices. Apple themselves has gone from the A10 having 2 fast 2 efficiency(slow) configurations to 2 fast, 4 efficiency cores in the A11. They weren’t just inspired by you linking to your MOAR CORES picture on your blog. There’s real world advantages to having them. They didn’t become idiots overnight and just add more slow cores for no reason.
The more simplistic, slower cores actually make a big difference to system performance. I don’t know the exact details of the A11 implementation, but I would be shocked if it isn’t very much a reflection of the ARM big.Little stuff.
Number 6: Are the power savings available from big.LITTLE significant at the system level?
Saving fifty percent or more of the power of the CPU subsystem is a significant saving at the system level. When combined with DVFS, power gating, clock gating, and retention modes, big.LITTLE plays in important role in the overall power management of a mobile device, and it brings opportunities for future power reduction as software power management policies evolve and work more closely together to manage shut-down, core migration, voltage, and frequency in a coordinated policy. Bottom line, the power reductions are very good now, and they will get even better.
Number 7: Can big.LITTLE save power on high performance tasks too?
High performance applications have periods of lower intensity, for example when waiting for user input or while the GPU is active. During these periods, existing smartphone SoCs downshift to lower DVFS points and/or idle the cores. From the diagram below, we can see that during play, an HD racing game causes the DVFS mechanisms to idle the dual-core Cortex-A9 CPUs almost half the time, while operating below 1GHz over ninety percent of the time. All of these idle periods and low frequency states map well to LITTLE cores and present the opportunity to save energy, even for a high performance workload like the GT Racer HD game.

Obviously faster chips are good and all, but it isn’t a simplistic trade off of speed vs cores vs power utilization on the overall system level. Oh, and price matters to a lot of people too.
