For Cuda which is Faster ?

Hello,

For Cuda which is Faster/better to get ?

8800GTX or Quadro FX 4600 ?

Also is their a differnece between 8800GTX & 8800Ultra for Cuda ?

Thank you,
Jeff

Just compare number of multiprocessors and their clock frequency.
Both 8800GTX and Ultra have 16 multiprocessors but Ultra is clocked higher (1500MHz vs. 1350MHz for GTX). So, Ultra will be a bit faster for kernels where calculation is the bottleneck.

Hello

Thank you for your reply.

But what about compared to Quadro FX 4600 ? Which is faster/better for CUDA ?

Thank you,
Jeff

I can’t find specs for FX4600 on NVIDIA website. I suppose there are 16 multiprocessor clocked at 1500 MHz (as Ultra), but I’m not sure.

Anyway, I don’t see the point of getting Quadro for CUDA (unless you need a lot of memory, in which case FX5600 may be a good choice). High-end GeForce boards provide same performance and are much cheaper.

Appendix A in the programming manual shows that the FX4600 only has 12 multiprocessors

Yes, the FX4600 has the computational power of the 8800 GTS (96 processors) but the memory of a GTX (768 MB).

Quadro does have advantages in terms of additional graphics features and improved reliability (since they are manufactured and tested by NVIDIA).
