Can I deduce that the CPU A is roughly twice as fast as the CPU B

[yonngcheng]

Hi, dear all,
I am interested on the CPU Mark, especially the “CPU-Integer Math”. I want clarify my question with an example:
CPU A: Value of CPU-Integer Math = 1000
CPU B: Value of CPU-Integer Math = 500
Can I deduce that the CPU A is roughly twice as fast as the CPU B for Integer calculation?

How about the other Marks?

Yes, broadly speaking.
But in real life it isn't so simple. There can be differences between 32bit and 64bit, differences depending on the instruction mix (division is always very slow), differences depending on how much RAM the algorithm in question uses & differences depending on how well threaded an algorithm is.

Thanks a lot. Can i get the seprate list about CPU-Integer Math instead of the CPU mark? I can't not find such information on the portal. Does somebody know more details?

We don't have a chart with just integer maths on it.
We could prepare some custom dumps of the data for you, but there would be a cost.

The closest public data is the CPU chart

and single threaded chart
