The GTX 470 is of course the baby of the two new models due out from NVIDIA. Of course, we use the word 'baby' quite loosely. On the specifications front the model carries with it 448 CUDA cores, 56 Texture Units and 40 ROP Units. All these are done on a 40nm core which we figure has been the biggest issue for NVIDIA when it has come to the release of this card.
Below you can see a GPU-Z screen shot of the model. Having a look at it, we can see all the main MHz that we need to know about. The core comes in at 607MHz while the shader clock carries with it a 1215MHz clock.
As for the memory, we're seeing NVIDIA use GDDR5 for the first time on a high-end product; they're using a 320-bit memory bus which is the reason we have a slightly weird sounding 1280MB of total memory. This comes clocked in at 837MHz or 3348MHz QDR.
NVIDIA cards of course offer some great features which are lacking on ATI cards. To some people, however, these features simply don't matter. For gamers the big selling point is of course PhysX of which support is growing for on a regular basis; there's no denying that uptake isn't fantastic, though.
CUDA is another big selling point, but really only aimed at a certain crowd outside of gamers. There are a number of great applications that support the technology and it's extremely useful in some scenarios.
Also included is Ray Tracing and some new Anti-aliasing support. I highly recommend that if you want to learn some more about these technologies, you check out the article that was posted just before this; GTX 400 Series - What you need to know. It not only covers the features in some more detail while also looking at Surround Gaming, but also the specifications of both the GTX 470 and GTX 480 while at the same time looking at some of the topics that have ran rampant over the past six months.
