How to Choose a GPU for LLM Inference
Choosing a GPU for LLM inference starts with the model, precision, concurrency target, and latency budget. Teams overspend when they shop by brand first and workload shape second.
- First input
- Model size
- Parameter count and quantization set the VRAM floor.
- Second input
- Traffic pattern
- Single-user tests and production concurrency are different problems.
- Best shortcut
- Start with fit
- If the model cannot fit, every other optimization is irrelevant.
Choose the smallest healthy route that fits your model and traffic target.
Start with the model's approximate VRAM requirement, then work backward from concurrency and latency goals. The goal is not the most powerful GPU; it is the lowest-friction route that fits and performs cleanly.

- Fit first, then throughput, then cost.
- Quantization often changes the answer more than vendor branding does.
- Routing layers make this repeatable instead of per-model guesswork.
Practical guidance
The inputs that actually matter
Teams get cleaner decisions when they anchor on model size, precision, expected load, and latency target. Shopping by GPU family before those are clear leads to waste.
- Model and precision
- Expected request volume
- Latency ceiling
- Budget or cost target
Why static lookup charts are not enough
Static charts are useful for learning, but real deployment decisions depend on current healthy supply. The right route for a model this week may not be the right route tomorrow if the market changes.
How Jungle Grid changes the workflow
Instead of forcing an exact GPU pick for every model, Jungle Grid lets you submit the workload and handles placement against available capacity. That gives you one operating model across multiple workloads and providers.

FAQ
Frequently asked
What is the biggest mistake in GPU selection for inference?
Choosing for peak safety without respecting actual workload shape. Teams then pay a premium for headroom they do not use.
Where can I find requirements for a specific model?
Because the user often wants the concrete follow-up immediately, such as the GPU requirements for LLaMA or Mistral rather than only the framework for thinking.
What should I do after reading this?
Use it to narrow the problem, then jump into a model page or pricing estimate when you want a concrete route and cost range.
