So is this correct? ARMv7 Cortex A15 > ARMv7 Cortex A7 > ARMv7 Cortex A9 > ARMv7 Cortex A8 > ARMv6 ARM11xx > ARMv3 ARM7xx

- Symmetry 15y agoWell, sort of. The ordering depends on the frequency each of the cores is run at and that depends on the process node as well as the architecture. The A7 is only expected to get 1.9 DMIPS/MHz while the A8 gets 2.0, but the A7 is designed for much faster clock speeds so it ought to perform better than even most A9s. EDIT: I just submitted an Anandtech article that explains all this much better. EDIT2: Oops, someone else had already submitted it and now its off the top of the "new" page. How this article beat it out is beyond me.

- aphexairlines 15y agoThank you, that article helps a lot.
- masklinn 15y agoPower wise, I believe it's A9 > A7.
- lgeek 15y agoAlso useful to remember that A15 and A7 are binary compatible and that these are the only cores which support LPAE.
- wmf 15y agoNo. A15 > A9 > A7 > A5 > M4 etc.
