Best AI Models for NVIDIA Tesla M40 24GB (24.0GB)
Maxwell (2015): no Tensor Cores, slow FP16, GDDR5 — the cheapest 24 GB card but also the slowest here. Passive server card; needs added cooling.
24 GB is the enthusiast tier for running AI models locally. It comfortably handles 7B–13B models at high quality and opens the door to larger 30B models at moderate quantization.
This is one of the most popular memory tiers for local AI, found in GPUs like the RTX 4090 and RTX 3090. You can run Llama 3 8B, Mistral 7B, and Qwen 2.5 7B at Q5_K_M or Q6_K quality with fast token generation and generous context windows. Larger 14B models like DeepSeek R1 Distill fit comfortably at Q4_K_M. For even bigger models, 30B class runs at Q2–Q3, but 70B models are generally too heavy for single-GPU inference at this tier.
Runs Well
- 7B models (Llama 3 8B, Mistral 7B) at Q5–Q8 quality
- 13B–14B models at Q4–Q5 quality
- Small models (3B–4B) at FP16 precision
- Multimodal models like LLaVA 7B
Challenging
- 30B models only at Q2–Q3 quantization
- 70B models do not fit in VRAM
- Large context windows with 14B+ models

Frequently Asked Questions
- Can NVIDIA Tesla M40 24GB run Qwen3.6 27B?
Yes, the NVIDIA Tesla M40 24GB with 24 GB can run Qwen3.6 27B, Gemma 3 27B IT, Gemma 4 26B A4B IT, and 1520 other models. 447 models run at excellent quality, and 528 at good quality. Check the compatibility table above for the full list with VRAM usage and estimated speed.
- Is NVIDIA Tesla M40 24GB good for AI?
The NVIDIA Tesla M40 24GB has 24 GB of GDDR5, making it excellent for running local AI models. It supports 975 models at good quality or better. With 288.0 GB/s memory bandwidth, it delivers reasonable token generation speeds. This is an enthusiast-grade GPU that handles most popular open-source LLMs.
- How many parameters can NVIDIA Tesla M40 24GB handle?
With 24 GB, the NVIDIA Tesla M40 24GB supports models from 3B to 30B parameters depending on quantization level. At Q4_K_M (the recommended sweet spot), you can fit roughly 40B parameters. This means 7B models at high quality (Q6/Q8) or 30B+ models at Q4.
- What quantization should I use on NVIDIA Tesla M40 24GB?
For the best balance of quality and speed on the NVIDIA Tesla M40 24GB, start with Q4_K_M — it preserves ~85% of the original model quality while keeping VRAM usage reasonable. With 24+ GB, you have the headroom to run 7B models at Q5_K_M or even Q6_K for noticeably better output quality. For larger 30B models, Q4_K_M remains the sweet spot.
- How fast is NVIDIA Tesla M40 24GB for AI inference?
With 288.0 GB/s memory bandwidth, the NVIDIA Tesla M40 24GB achieves approximately 42 tokens/sec on a 7B model at Q4_K_M — that's very fast, well above conversational speed. A 14B model runs at ~21 tok/s. Token generation speed scales inversely with model size — smaller models are significantly faster.
tok/s = (288 GB/s ÷ model GB) × efficiency
Smaller models = faster inference. Memory bandwidth is the main bottleneck for token generation speed.
Estimated speed on NVIDIA Tesla M40 24GB
~11 tok/s~10 tok/s~11 tok/s~10 tok/sReal-world results typically within ±20%. Speed depends on quantization kernel, batch size, and software stack.
- What's the best model for NVIDIA Tesla M40 24GB?
The top-rated models for the NVIDIA Tesla M40 24GB are Qwen3.6 27B, Gemma 3 27B IT, Gemma 4 26B A4B IT. The best choice depends on your use case: coding assistants benefit from code-tuned models, while general chat works well with instruction-tuned models like Llama or Qwen.
- What power supply and cooling does NVIDIA Tesla M40 24GB need?
The NVIDIA Tesla M40 24GB has a TDP of 250 W. A good rule of thumb is to provide at least double the GPU's TDP to cover the rest of the system — that means a 550 W PSU or larger. A mid-tower case with one intake and one rear exhaust is usually sufficient. Keep dust filters clean, as sustained inference generates continuous heat rather than the brief spikes typical of gaming.
- Anything to watch out for with NVIDIA Tesla M40 24GB?
Maxwell (2015): no Tensor Cores, slow FP16, GDDR5 — the cheapest 24 GB card but also the slowest here. Passive server card; needs added cooling.
