Sapphire Radeon HD 6790 Graphics Card Review

GPU Computing

GPU computing is something which is fast becoming a very important feature on "video" cards. NVIDIA have a number of useful utilities for CUDA enabled cards which all help to enhance the performance of day to day tasks. On the AMD front we have "Stream" applications which use the GPU to enhance performance. Here we have taken an example of the different technologies at work to find out how the cards benefit us in real world use.

GPU Assisted Media Conversion
Our media encoding test takes a 4GB 1920x1080 file and converts it with Arcsoft Media Convertor 7 or Badaboom 2.0 to iPad format with GPU assistance.

Benchmark Results

When converting video there is a clear advantage for our NVIDIA card when running Badaboom and that allows the 550 Ti system to finish around 11 seconds ahead of the Radeon, something that trends across a number of GPU computing scenarios. That said we still do see performance improvements over CPU only performance when using our Radeon GPUs.
