I'm working for a mechanical engineering firm that specializes in vibration modeling (mainly for NASA). We're trying to see if GPGPU computing is a good fit for our applications (models).
We're considering using either a Radeon 3870 or a FireStream 9170 (possibly a Radeon 4850, if it's practical in the near term?). For the purpose of proving the applicability of GPGPU computing for our model codes, would a dedicated Radeon 3870 suffice or is a FireStream 9170 required? With the FireStream 9250 on the cusp, I'd prefer to start with the Radeon 3870 (or possibly the 4850) and move over to the FireStream in September.
What's the scoop?
