Popular Use Cases for NVIDIA AI GPUs

Training and inference for large language models

Large-scale natural language processing is powered by NVIDIA AI GPUs. They can support:

• Training enormous models like GPT, LLaMA, Mistral, Claude, etc.
• Low-latency inference at scale for real-time chatbots, translation, summarization and content generation.
• LoRA and fine-tuning of domain-specific applications with smaller datasets.

Such workloads usually demand multi-GPU systems or cluster-based systems with A100, H100 or GH200-series GPUs and NVLink and high-performance networking (InfiniBand).

Computer vision and video analytics

The NVIDIA GPU has an enormous advantage in AI models that operate on images and video, such as object detection, face recognition, and surveillance analytics, because:

• Video streams that have high frame rates to be processed in real time.
• Convolutional neural network (CNN) deep learning acceleration, image segmentation, and optical flow.
• Edge-to-cloud implementation of solutions such as NVIDIA Jetson (edge devices) and DGX systems (data center).

Use cases examples include retail analytics, smart city infrastructure, traffic management, medical imaging, and industrial automation.

AI research and academic usage

NVIDIA GPUs are common in universities and research facilities to:

• Try new model architectures and training strategies.
• Perform massive simulations in such areas as physics, biology, and climate science.
• Donate to open-source AI such as Hugging Face and PyTorch.

The GPU-accelerated computing is flexible in that it enables researchers to test new hypotheses with little time spent waiting on the CPU-based systems.

Performance and Benchmark Highlights

Inference Throughput Benchmarks

Regarding the speed of inference, NVIDIA Tesla H100 is the overall champion in all benchmark tests. It delivers:

• Faster results on large-scale language models such as GPT-3, GPT-J and BERT.
• Low latency performance, which is essential to real-time use cases such as chatbots, semantic search and voice assistants.
• Scalability, the ability to be deployed easily in multi-GPU or cluster settings without performance loss.

It is based on the H100 architecture which runs thousands of inferences per second with a dramatically reduced compute overhead than previous generations, powered by fourth-generation Tensor Cores and Transformer Engine.

Training time comparisons

To be efficient in training, the NVIDIA RTX 6000 Ada Generation (PRO) presents quite astonishing outcomes:

• It trains mid-sized models (e.g., ResNet-50, LLaMA-7B) up to 35 percent faster than older-generation GPUs such as the RTX A6000 or V100.
• Perfect fit to developers and data scientists who perform iteration-based training and fine-tuning and quick prototyping.
• Supports larger in-batch sizes and faster convergence rates with the higher memory bandwidth and better tensor performance.

This speed can be used to reduce the time it takes to develop and also iterate the models more often.

Power efficiency and thermal performance

The new generation of AI GPUs produced by NVIDIA are designed not only to be fast, but also to be energy efficient and thermally optimized:

• Top performance-per-watt: throughout the product range, including data center-level H100s, to workstation-level RTX GPUs.
• High-end cooling solutions, such as vapor chambers, and dynamic fan control make the system stable at high loads.
• Eco-friendly deployment of AI-supported systems- less energy used, less money spent on operations, and fewer carbon emissions.

This performance-efficiency combination makes them well suited to hyperscale data center and on-premise AI infrastructure.

How to Choose the Best NVIDIA GPU for AI

The appropriate NVIDIA GPU to use in your AI workloads will vary depending on several factors such as the task (training or inference), project size, budget, and infrastructure. The decision making process is examined in more depth below:

Use-Case-Based Selection: Training vs. Inference

Inference Workloads

To run trained AI models in production or in real-time systems, you want low-latency and high-throughput optimized GPUs. Recommended options:

• NVIDIA A100: Tested inference capabilities with language models, vision models and recommendation systems. Perfect to deploy on a large scale.
• NVIDIA H100: new architecture, including Transformer Engine support, which provides major speed-ups to LLM inference, with improved efficiency.

Such GPUs are perfectly suited to real-time chatbots, recommendation engines, edge-to-cloud inference systems, and batch-based prediction systems.

Training Workloads

Performance in training is paramount as regards model development, especially in case of large data or complex architecture. Choose:

• RTX 5090(Ada): A consumer grade high-end GPU with great FP16/BF16 performance and sufficient VRAM on small to mid-size models.
• RTX 6000 Ada Generation (PRO): It is made to work with intensive training and has a high memory and professional level reliability.

Such cards are very good at fine-tuning, transfer learning, training vision models, and experimenting with LLMs on a workstation or a lab system.

Budget Considerations vs. Performance Scaling

It does not require the best hardware to begin with every project. This is one way of doing it:

Entry-level GPUs (e.g., RTX A4000, A5000) are the best choice to test code or conduct small-scale experiments or learn.

• When the model size and user traffic increases, upgrade to A100, H100 or multi-GPU configurations.
• Take advantage of cloud GPUs or hosted bare metal to have flexibility without making any upfront capital investment.

This is useful to trade-off between performance needs and monetary limitations, particularly in the case of start-ups, research & development teams, or research labs.
