GPU memory and RAM
GPU memory usually limits model size; RAM supports apps, data, and model offload.

Notes
Current AM5 X870 board with two rear USB4 ports, Wi-Fi 7, 5GbE, and four M.2 slots; review documented PCIe/M.2 lane sharing for the final device layout.
Needs GPU VRAM too
System RAM helps tools and offload, but GPU-accelerated model fit is limited mainly by VRAM.
AI terms in plain language
CUDA
NVIDIA’s software layer for many AI tools. Macs and AMD GPUs do not run CUDA workflows the same way.
Apple unified memory
Memory shared by the CPU, GPU, macOS, and apps; it is not the same as NVIDIA VRAM.
7B / 8B / 14B / 70B
Approximate model size in billions of parameters; larger models usually need more memory.
Quantized models
Lower-precision models, such as Q4, that use less memory with possible quality or speed tradeoffs.
Context length
How much text the model can keep in mind at once. Longer context uses more memory.
Inference
Running an existing model for chat, coding help, summaries, or document workflows.
Fine-tuning vs adapter tuning
LoRA and QLoRA train small adapters and need fewer resources than full fine-tuning.
Throughput (tokens/s)
Model output speed. Compare the same model, quantization, context, runtime, and user count; prompt processing is a separate measurement.
