What exactly does processor TDP refer to? I have an i7-4870HQ in my 15" MBP with a TDP of 47W. If I really push the processor though, it jumps up to 60W with turbo (and almost instantaneously goes from ~40 °C to > 90 °C). Is TDP in reference to the base frequency (i.e. 2.5GHz in the i7-4870HQ)? I certainly realize these processors aren't designed (with a MacBook Pro anyway) to run at the turbo frequency on multiple cores for any extended period of time. I'm just curious what exactly it's referring given that 60W is significantly higher than 47W.
