You’re calculating the performance per watt wrong on many of the newer cpu’s you guys are adding, you’re supposed to calculate it using the PL2 instead of the PL1. 45-80 watts is being used when running these benchmarks so the performance per watt is very misleading. (For the x9 388h) Also this isn’t the only chip that gets calculated this way as i’ve stated earlier so PLEASE fix this problem.
