Trying to predict how many math calculations Intel i3 4025U can do per second

snowmagician · 12-14-2017, 04:21 PM

There are 4 cores and each core is 1.9Ghz

I learned that 1Ghz means 1 billion bits per second.

This is my calculation

1.9Ghz = 1.9 billion bits per second

1.9 billion bits per second = 237.5 million bytes per second

237.5 million bytes per second

If each calculation requires roughly 0.1 million bytes per second then

i3 4025U with 4 cores at 1.9Ghz

2370 x 4 = a bit less than 10K math equations per second?

Thanks a lot Linux Questions!!

That is not correct.

1GHz means one billion cycles per second. Usually that means the base clock frequency when used with respect to CPUs, and relates to data throughput and math calculations per second in many different and complex ways, dependent both on the chip type and the specific calculation.

Also: this is the measure you're looking for.
