Another good article, and i definitely like the idea of more regular smaller, and as a result simpler/easier to understand,
articles.

A good if somewhat basic analysis of modern GPU's.
I'm interested as to weather or not you did any testing / theorizing that took into account memory bandwidth, prior to ignoring that factor?

I cant help but think *purely guessing though* that if you added a scaling factor that accounted for differences in memory bandwidth, that your results might be even more accurate, especially when generalizing from the laptop to the desktop version of the cards.

EG. Memory bandwidth / number of processing cores
( or maybe establish a baseline memory Bandwidth for each model of GPU, and then compare against that....

Also interested as to why you chose notebookcheck.net as your data source? Why not use Anand/Hardocp/techreport and compare desktop GPU's?


Oh and i would have been interested to see results from the new VLIW4 ati cards, even if the are outliers and represent a different architecture.

Cheers,

PiedPiper
