granularity equals bus width times prefetch is a simple FACT.

LOL, is that coming from our resident mathematician? I would think a mathematician would break down this equality to the smallest common denominator.

What I don't like about this equation is that 'Bus Width' is a dependent variable.

For example, we start with a graphic card design and it has some given memory bandwidth requirement. After you choose what type of memory to use, the bus width falls into place. The bandwidth requirement is the independent variable while the bus width is the dependent variable.

So here's the math to break down elixe's equation to the smallest common denominator:

Granularity = Bus Width * prefetch

Where: Bus Width = bandwidth / (core clock * prefetch)

Substituting the 'Bus Width' quantity into the first equation we get:

Granularity = [bandwidth / (core clock * prefetch)] * prefetch
Granularity = bandwidth / core clock

LOL, would you call that a simpler FACT?

You may want to suggest to elixe to give it up. Ha.
