I consider price and TDP as the two important variables, for performance, that aren't completely reconcilable. They should be considered separately, and then together for a buying decision for example. To illustrate and acknowledging that this calculation is more practical than satisfying to mathematicians: I wouldn't say that a chip that takes half of the power and costs half as much, while performing three times better, than a decade old chip is twelve times better all around. Even though the gains exceed both those indicated by price and watts, taken on their own. It performs roughly six times better per dollar spent and watt consumed, respectively. These performance differences are not reconcilable into a single number that most would quickly understand, but they should be considered together. And this in fact was the specific situation for the processor that I replaced. Not accounting for processing improvements that aren't included in thread processing speed. Try playing 4k video with a decade old processor while monitoring its utilization. Not to be argumentative as everyone is certainly entitled to their own weighting. I value TDP more than I do dollars spent. Though, both will always be unavoidably important.
