HD 7870 poor folding performance low usage

post #1 of 3
Thread Starter 
recently switched to AMD for the first time ever.
expected GCN to be fast at compute but it is terrible at F@H.
gpu usage is 60-70% while folding (compared to 99% for nvidia) and ETA is 7 hours (compared to 1-1.5 hours for nvidia)
there are also instances where the gpu client cpu usage spike to 25% (a full core) for a few seconds, which leads to GPU usage spiking to 99.99% for the same amount of time before cpu go down to 5% and gpu goes down to 70% again.
i don't know what is wrong. does AMD just suck?

The core currently in use was meant for the HD 5000 series.
They haven't updated it because of AMD's OpenCL compiler bugs.

The hardware is more than capable, but the software is not.
