Hey can someone else double-check that the formula being used on Page 2 for Perf/Dollar is actually making sense?<p>They had three measures:
A) Flops. Operations per second.
B) Cost. Dollars per hour.
C) Runtime. Seconds per task.<p>I expected the formula to be Flops/Cost, resulting in units of operations per dollar.<p>Instead it was computed as Flops / (Cost * Runtime), to get some units that don't make sense to me — operations * tasks per dollar seconds?
> Not only was the Google Axion processors delivering great performance in Google Cloud but doing so with the best performance-per-dollar too.<p>Nice upgrade for Google's customers. I'm guessing it does it at much lower wattage as well.
> These new C4A instances are advertised as offering up to 50% better performance and up to 60% better energy efficiency than their current generation x86 instance types.<p>Hardware (see also, Google's TPUs and their performance vs. energy cost) is one reason why I'm fairly bullish on Google.
