Sorry, didn't mean to sound like I'm doubting your information, was just pointing out "statistics" isn't a very accurate way of comparing GPUs from different companies nowadays and the GTX470 is superior stats wise on the only stats that you can really compare fairly, the Vram.
Checking GPUreview, You probably meant the fill rates and OP/s. The fact is with modern GPUs and how different they are architecturally its not really relevant.
That's a great answer and makes a lot of sense especially with the proprietary way most companies do business these days. Few if any meaninful apples to apples comparisons keeping me ( the average buyer) in the dark. Thanks, you have been very helpful.
