Quadro 5600 FX

Accelerated Computing CUDA CUDA Programming and Performance
1

In the forums, most folks are understandably looking at the 8800 GTX, but I was wondering about the most recently announced release. Our application may not be so much as financially limited, but capability limited. So, I am hoping for more specifications.

The Quadro 5600 FX states that it supports CUDA programming, but gives very few details after that. The tech specs read 1.5 GB GDDR3 with 76.8 GB/s memory bandwith, etc… [url=“http://www.nvidia.com/docs/IO/40049/quadro_fx_5600_datasheet.pdf”]http://www.nvidia.com/docs/IO/40049/quadro...0_datasheet.pdf[/url]

All of this looks promising. Specific CUDA questions:

Q1: Does the Quadro 5600 FX support 64-bit floats for CUDA programming?

Q2: How do the number of multi-processors compare to the 8800 GTX?

Q3: Estimates on CUDA performance for codes (FLOPs, or other reference comparisons)?

Q4: Any other significant differences (for CUDA) between the two architectures?

I appreciate any extra information provided.

Q1: Does the Quadro 5600 FX support 64-bit floats for CUDA programming?

   No

Q2: How do the number of multi-processors compare to the 8800 GTX?

   Same number

Q3-4:

    Not currently. Future features like double precision will be only available on Quadro.

Quadro cards have a 3-years warranty vs 1-year of the 8800 GTX.

Quadro cards also undergo much more stringent testing and qualification by NVIDIA. GeForce cards are built and tested by separate board manufacturers and testing and qualification is up to them.

Quadro FX 5600 also undergoes additional memory qualification tests that other boards (including other Quadros) don’t undergo, to help ensure the best quality memory is used and reduce the occurance of errors.

Thanks for the quick reply from NVidia guys :)

So basically, the Quadro 5600 FX is a Geforce 8800 GTX with more memory and better (or at least known) quality control?
