There was an article in some embedded magazine last year about how they were seeing a trend in automotive to fewer bigger CPUs, rather than more, smaller. Mainly for load balancing. If you have 16 CPUs of performance level 1, and you have 3 tasks that require performance level 2 and 12 that require performance level 0.5, you are out of luck. But if you have 4 CPUs each of performance level, say, 8, it all fits. Heck, even parity, performance level 4x4. Parallelism is good. Load balancing is hard.
