Specs:- GeForce 8800 GTX and GTS Compared

With all the pages of technology discussed that encompass the GeForce 8800 GPU, just how complex is it? Hold you breath and read this:- six hundred and eighty one million transistors. Yes, you read it right, it's really 681 million transistors. That's nowhere near any mainstream graphics processor ever made or CPU for that matter. Instead, it's got enough transistors to perhaps challenge the Itanium server processor. What's more interesting is that it's still fabricated on a 90nm process technology. You just got to wonder what's NVIDIA's yield rate of these monster GPU, but as with all public relations talk, it's all too rosy to believe. Both variants of the GeForce 8800 series will use the same G80 GPU, so perhaps the lower binned versions get marked up for the GeForce 8800 GTS cards. Here's the full specs of the GeForce 8800 graphics cards discussed and how it stacks up to some of its predecessors and relevant comparisons:-

The more appropriate query for the enthusiasts is if there will be enough of G80 GPUs being churned out to keep to NVIDIA's suggested retail price. The GeForce 8800 GTX is slated to go for US$599 and the GeForce 8800 GTS at US$449. These figures are probably what some of you have dished out to obtain the GeForce 7950 GX2 and the GeForce 7900 GTX once upon a time. So it's really interesting to see these aggressive price points offered that's actually eating out the aforementioned GeForce 7 series SKUs. At the time of writing, here's the updated suggested retail price for all of NVIDIA's graphics cards:-

GeForce 8800 GTS 640MB $449
GeForce 7950 GT 512MB $299
GeForce 7900 GS 256MB $199
GeForce 7600 GT 256MB $159
GeForce 7600 GS $129
GeForce 7300 GT < $99
