NVIDIA GeForce RTX 4070 vs NVIDIA Tesla P40
Side-by-side comparison for AI and gaming. Which one should you buy in 2026?
Bottom Line
NVIDIA Tesla P40 wins — more VRAM at the same or lower price. No contest for AI.
AI Model Compatibility
How each GPU handles popular AI models. VRAM determines whether a model fits — green means it runs, red means it won't.
Estimated Performance (tok/s)

NVIDIA GeForce RTX 4070
The RTX 4070 offers solid 1440p gaming performance at a reasonable price point. With 12GB of GDDR6X and low 200W power consumption, it is efficient and capable. For AI use, the 12GB VRAM handles 7B-8B models at Q4-Q8 quantization. It is a popular choice for budget-conscious gamers, though the 4070 SUPER offers better value if you can stretch the 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.
