Calculate computer performance increase?
I'm trying to figure out how to calculate the increase in performance between PC configurations.
For instance:
PC X takes 0:13:15 (h:mm:ss) to render a 5 minute video
PC Y takes 0:04:31 (h:mm:ss) to render the same 5 minute video
Basically, how much faster is PC Y than PC X in this situation?
It's confusing for me because the new value is lower than the original. I tried the formula
(increased amount - original amount) / original amount x 100
but it gives me a number that doesn't look right.
I hope I can get an answer to this, I'm starting to feel dumb (Headbang)

The processor speed is inversely proportional to the time taken for the standard task. So use 1/t rather than time in your calculations.

OK, now I'm an idiot.
Can you explain any further?

First get rid of the minutes and seconds format, it's much easier to work with only one unit.
PC X has a processor speed of 
and PC Y has a speed of 
where 
is a constant.
Can you continue?
