Media Encoding

GPU Assisted Media Conversion

Our second media encoding test takes a 4GB 1920×1080 file and converts it with Arcsoft Media Convertor 7 to iPad format. One run is completed with CPU only encoding, the second with NVIDIA GPU.


Music Encoding
Our music conversion test takes an 18 track lossless album and converts it using dBpoweramp into 128Kbps Mp3 format. dBpoweramp is a multi-threaded application which allows us to convert a track on each core/thread, at any one time.


As the Edge-HD2 features an NVIDIA GPU we can take advantage of the numerous applications available which support CUDA. This means that in applications such as Arcsoft MediaConvertor we can pass some of the processing work to our GPU, leaving the CPU free to do other tasks. For this particular test this means the reduction in encoding time of 6 seconds which freeing up 8% of CPU resource for other tasks on our Sapphire system.

For music encoding, the Edge-HD2 also performs at a good level. Being able to convert a full album from disc to MP3 in under 5 minutes should be more than enough for most consumers and is very much down to the fact the system can process 4 tracks at any one time thanks to its dual core design with Hyper-Threading. We also see a clear benefit from the new architecture which is 21 seconds faster than the original Edge-HD.
