> To achieve that 10% speedup, it ate up about 20% more power, so efficiency-wise, it's not worth it.
There’s a trade off between single threaded performance and power, right? I’d expect the increase in power cost to be between the performance increase squared or cubed. If you expect a one-to-one trade it is never worth it to increase frequency, haha.
The universe will give you throughput at a fair rate, but it is very stingy about latency, in general.
