AI and machine learning are no longer the exclusive domain of cloud data centres. With the right workstation, Nigerian researchers, students, and engineers can train models, run inference, and iterate on datasets locally — without cloud bills or latency.
GPU First, Everything Else Second
In ML workloads, the GPU is the computational core. NVIDIA CUDA is the industry standard — PyTorch, TensorFlow, and virtually every ML framework is optimised for CUDA. AMD GPUs can work via ROCm, but ecosystem support is still narrower.
The key GPU spec for ML is VRAM. Model size is primarily limited by VRAM:
- 8GB VRAM: Small models, fine-tuning quantised LLMs (7B parameters at 4-bit)
- 16GB VRAM: Mid-size models, computer vision at batch size 32+, BERT-large fine-tuning
- 24GB VRAM: LLM fine-tuning (13B+ at 4-bit, 7B at full precision), larger vision models
For most ML practitioners, start with an RTX 4070 12GB or RTX 4090 24GB depending on budget.
Multi-GPU Considerations
Two RTX 4090s give you 48GB VRAM for large model training. This requires a motherboard with multiple PCIe 4.0 x16 slots, a 1600W PSU, and aggressive cooling. It's a serious investment but delivers results that would otherwise require cloud spending in the hundreds of thousands of naira monthly.
CPU and System Memory
The CPU in an ML workstation handles data preprocessing, model loading, and CPU-bound operations. A high core count helps:
- AMD Ryzen 9 7950X (16 cores) or Ryzen 9 9950X — excellent for multi-threaded preprocessing pipelines
- RAM: 64GB minimum, 128GB for large dataset preprocessing — this is one of the few use cases where 128GB is genuinely warranted
Storage for ML
Training datasets can be enormous. A fast NVMe SSD as your working drive prevents I/O from bottlenecking training. A large HDD or RAID array stores the full dataset library. At minimum: 2TB NVMe + 8TB HDD.
