Hi, it’s said Quadro4600 uses PCB of 8800, what’s the difference? Could anyone point to some materials (ppt, webpage, pdf…) about Quadro at Mar.7th ?
Thanks!

I could be wrong but the quadro 4600 we have is basically a geforce 8800GTS with 768MB. I.e it only has 96 shaders but has 768 MB of RAM and is clocked at the GTS speed. So it is like 8800GTS with a bit more ram. Performance wise in cuda i found the GTX cards to be faster. The quadro 5600 is more like a GTX card i.e. 128 shader units with 1.5GB of RAM slightly underclocked but the memory seems to run a lot slower the the GTX cards. Hope this helps

In the latest version of the Programming Guide (0.8.1), in Chapter 5 there is a table that compares the GeForce 8800 and Quadro FX 5/4600 (number of multiprocessors, clock. memory).

There are also other differences that are important for some users:
the Quadro line has a 3 years warranty and is tested for professional use.
