Local AI Architecture
To run Llama 3 70B at a usable 4-bit quantization (Q4_K_M), you need approximately 40GB to 48GB of VRAM. This typically requires either a Mac Studio M2/M3 Ultra with unified memory, or a multi-GPU setup like 2x RTX 4090 or 2x RTX 3090.
Apple's Unified Memory offers massive capacity at a lower price point than enterprise GPUs, making it excellent for running huge models (like 70B or 104B parameters) that wouldn't fit on a single consumer GPU. However, for smaller models that fit entirely within a single RTX 4090 (24GB), the dedicated GPU will offer significantly faster token generation speeds.
Yes, you can offload layers to system RAM using frameworks like llama.cpp. However, system RAM bandwidth is typically around 50-90 GB/s, whereas a dedicated GPU like the RTX 4090 provides over 1000 GB/s. Offloading to system RAM will cause a massive bottleneck, resulting in very slow token generation speeds.
Currently, the best budget GPU for Local AI is a used RTX 3090 (24GB VRAM). It offers the same VRAM capacity as the RTX 4090 at a fraction of the cost, making it the king of budget inference. For brand new options, the RTX 4060 Ti 16GB offers a good entry point.
