Yeah, there was no way to pretend the Cell was anything close to a traditional SMP design. But Intel's Lakefield and Arm's big.LITTLE are very much meant to be treated as SMP systems, with just a few tweaks on top to deal with/take advantage of the fact that they're not completely symmetrical. That means the CPU designers actually have to be more careful about what functional differences they allow to creep in.
