RTX 4090 Performance Benchmarks for AI/ML
While synthetic benchmarks provide a general idea of performance, real-world AI/ML benchmarks are more valuable. Here are some key performance indicators:
- Stable Diffusion: The RTX 4090 excels at image generation with Stable Diffusion. Expect significantly faster image generation times compared to older generation GPUs. Generation times can range from 10-20 seconds per image depending on the model and parameters.
- LLM Inference: For large language model (LLM) inference, the 24GB of VRAM is crucial. The RTX 4090 can handle smaller models entirely in VRAM, leading to low-latency inference. For larger models, offloading to system RAM might be necessary, impacting performance.
- Model Training: The RTX 4090 can be used for training smaller models or for fine-tuning larger models. It's not ideal for training massive models from scratch due to its limited VRAM compared to enterprise GPUs. However, techniques like mixed-precision training and gradient accumulation can help mitigate this limitation.
- General Deep Learning: In general deep learning tasks, the RTX 4090 offers a significant performance boost over previous generation consumer GPUs and even some older enterprise GPUs, making it suitable for a wide range of applications.
Best Use Cases for RTX 4090 in the Cloud
The RTX 4090 is well-suited for a variety of AI/ML workloads:
