NVIDIA GeForce RTX 3060 12GB vs NVIDIA Tesla P40
Side-by-side comparison for AI and gaming. Which one should you buy in 2026?
Bottom Line
NVIDIA Tesla P40 has more VRAM (24GB vs 12GB) but costs more ($300 vs $230). For AI, the extra VRAM is usually worth it. For gaming only, NVIDIA GeForce RTX 3060 12GB may be the better value.

NVIDIA GeForce RTX 3060 12GB
The NVIDIA GeForce RTX 3060 12GB has become a legend in the budget AI community. Despite its modest gaming performance, the 12GB of VRAM with full CUDA support makes it the cheapest entry point for running local LLMs. It handles 7B-8B models at Q4-Q8 and runs Stable Diffusion 1.5. Available used for around -230, it is the go-to recommendation for AI beginners on a tight budget.
Full specs →NVIDIA Tesla P40
The NVIDIA Tesla P40 is the ultimate budget AI card — 24GB of VRAM for around on the used market. Based on the older Pascal architecture (2016), it lacks modern tensor cores and FP16 acceleration, making inference significantly slower than newer cards. But for hobbyists who want to experiment with 32B models at Q4 quantization without spending thousands, nothing else comes close on price. Requires a second GPU for display output and runs with a loud blower cooler.
