ATI Stream vs. NVIDIA CUDA - GPGPU computing battle royale

[news 28]

Since our initial review of five of NVIDIA's CUDA-enabled applications back

in June, we've been chomping at the bit to get our first real look at ATI's

entry into the GPU computing ring called ATI Stream. Both of these platforms

use parallel computing architectures to utilize their GPU's stream

processors, in tandem with the CPU, to significantly increase any system's

video transcoding speeds. Today, we are going to discuss both of these

technologies as well as benchmark a couple video transcoding applications

from Cyberlink that actually support both CUDA and ATI Stream.

Quote: "While Stream's transcoding times were slightly better than CUDA in

most of our performance tests, CUDA seemed to produce a higher quality image

that evened things out a bit. Stream also seemed to be more efficient in

using less of the CPU's resources for transcoding while also producing fast

transcoding times. However, these transcoding times might be lower because

it is outputting lower-quality video files as our subjective image quality

tests suggest."

 

Thanks for a post!!
