### Optimal CPU-corecount / GPU balance ### Optimal CPU-corecount / GPU balance
**For a good price-performance ratio** use a mimimum of 6-8 CPU cores, add one core for every additional GPU. For Multi-GPU one core must be reserved per GPU. While multi-core CPU and multi-GPU efficiency decreases for every added CPU-core/GPU, multi-core CPU efficiency increases when addig more GPUs. **For a good price-performance ratio** use a mimimum of 6-8 CPU cores, add one core for every additional GPU. For Multi-GPU one core must be reserved per GPU. While multi-core CPU and multi-GPU efficiency decreases for every added CPU-core/GPU, multi-core CPU efficiency increases when addig more GPUs:
This means it is important to select a balanced system, according to the following observations made during benchmarking:
- multi-core CPU efficiency 50%-92% (depending on step and data) - multi-core CPU efficiency 50%-92% (depending on step and data)
- multi-core CPU efficiency increases by ~5% per GPU - multi-core CPU efficiency increases by ~5% per GPU
