Hi there, recently i've seen an article about a new ATI gpu from Sapphire.
It is the new Toxic HD5970 with 4!! GB of ram memory. This card would be awesome in GPU computing.

The question is: will CUDA for ATI development take so long? That's because I'm thinking to begin save some cash to get one of these babies :D

I'm no pro in this, but CUDA is unique to nVidia. It's something that nvidia came up with and it's not just about programming but also hardware architecture. Besides, I'm sure nvidia holds rights to CUDA and it's not something ATI cards can just use. Yeah I heard the ATI cards are pulling ahead as far as playing video games and doing benchmarks, but I'll stay with nVidia, just cause nVidia always has vision beyond games.

From Wikipedia:

"CUDA (an acronym for Compute Unified Device Architecture) is a parallel computing architecture developed by NVIDIA. CUDA is the computing engine in NVIDIA graphics processing units or GPUs that is accessible to software developers through industry standard programming languages."

Hi,

We currently only support Nvidia cards thru nvidia's cuda api, we are planning to add ATI support via OpenCL in the near future, once that api is more mature...

You have a good deal going right now with the 50% discount.
If I buy Octane today, will I be able to upgrade it to support Ati cards if you provide OpenCL support in the future, or will that be an upgrade I have to pay for?

Hi,

I cannot commit to an ATI version being delivered for our current v1.0 licenses at this time.

Thanks for the quick reply.

In other words I might as well look out for an NVidia card if I decide to get Octane.

there won't be an ATI version for long unless they decide to adopt Cuda.

OpenCL has poor performance on both platforms. I'v tested some OpenCL benchmarks and I had a few gigaflops\sec less than the same bench but on CUDA. On ATi ... :cry: I don't wanna say because I don't want you all cal me an idiot fanboy. http://www.anandtech.com/show/2977/nvid ... he-wait-/6 I.v also tested at work with a few guys and we get almost the same results :cry: .
