Graphics
This determines which AI models you can run and how fast.
VRAM decides which models fit. A 70B model at Q4 needs ~40 GB. If it doesn't fit, it won't run (or runs painfully slow from system RAM).
Bandwidth decides how fast they run. Two cards with the same VRAM can differ 3× in speed based on memory bandwidth alone.
Models come in quality levels, like video resolution. The original (FP16) needs the most VRAM. Quantized versions trade a small amount of quality for much less VRAM.
Most people use Q4 or Q6. A 70B model fits on a single 24 GB card at Q4 instead of needing 80 GB+ at full precision.
Memory
16 GB (1 sticks)
System RAM (not VRAM) is your multitasking headroom. While the GPU runs your model, RAM handles everything else: editor, browser, OS. 32 GB minimum for AI work; 64 GB lets larger models spill over from GPU VRAM without grinding to a halt.
Not enough RAM for this workflow
Code with AI locally needs at least 32 GB of RAM. With 16 GB, your system will struggle to run a browser, editor, and AI model at the same time.
Storage
1.0 TB (1 drives)
AI models are large files. Here's what typical models need on disk:
1 TB minimum, 2 TB recommended. A few models, a code editor, and your OS fill 1 TB fast.
