Funny maths, "As you can see, in Cinebench R23, the dual EPYC Milan 7763's are 34% faster than the dual Ice Lake Xeon 8380's."

- taneliv 5y agoYeah, I also wondered about that, isn't it more like 52% faster?
- TwoBit 5y agoDepends on how you define the math of "x% faster than"
- AussieWog93 5y agoThe English language defines the denominator in your equation as the object of the sentence. If you have 100 blue smarties in a bowl, and there are 20% more red smarties than blue, then you have 120 red smarties. There is no ambiguity.
- m463 5y agoI think that percentages shouldn't be used for things like this. Show an absolute time, how many units/second of work. percentages just (intentionally??) confuse things. the problem is that %faster and %slower are not equal
- tromp 5y agoIndeed, the EPYC is 52% faster than the Xeon, which makes the Xeon 34% slower than then EPYC.
- TwoBit 5y ago(113000 - 74000) / 113000 = 34%
- mkl 5y agoYes, but that's the opposite denominator from usual. If I say I got 50% more apples from my trees this year, I can only really mean (this_year - last_year)/last_year = 50% (i.e. 1.5 times as many).
- maesij 5y agoIncorrect. 74k should be in the denominator, that is what's being compared against (baseline).
