Achieving up to 125 TFLOPS of FP16 Tensor performance, the V100 represented a significant advancement for AI workloads. This powerhouse uses first-generation Tensor Cores to accelerate deep learning tasks efficiently. Let’s consider the table below that compares the NVIDIA V100 with H100
Feature | NVIDIA H100 | NVIDIA V100 |
---|---|---|
Architecture | Hopper | Volta |
CUDA Cores | 16,896 | 5,120 |
Tensor Cores | 528 (4th gen) | 640 (1st gen) |
Memory | 80GB HBM3 | 16GB or 32GB HBM2 |

The H100 significantly outperforms the V100, offering much higher compute power, memory capacity, and bandwidth. These architectural improvements and specialized features enhance its suitability for modern AI workloads.
One of the key factors in selecting a GPU is to find the right balance between training and inference performance. The performance of GPUs can vary significantly based on the type of model being used, the dataset size, and the specific machine learning task. GPUs can perform quite differently depending on the specific model type. Thus, the choice of the right one will depend on the requirements of the workload.
NVIDIA H100 can achieve the highest throughput for training large models such as GPT-4, BERT. It’s optimized for high-performance computing and advanced artificial intelligence research. In addition, it supports massive amounts of data and deep models with a large number of parameters.
The A100 is also great for training large models, though it doesn’t quite match the H100’s performance. With 312 TFLOPS for tensor operations and 2 TB/s memory bandwidth, it can handle massive models but with longer training times than the H100.
On the other hand, the V100 uses an older architecture. While it can be used to train large models, its low memory bandwidth and tensor performance of 125 TFLOPS make it less suitable for next-generation AI models.
It’s a good choice for AI researchers and developers for experimentation and prototyping but lacks the enterprise-level features of the H100 and A100.
Both the H100 and A100 perform very well with multi-instance GPU (MIG) capability, which enables inference tasks to run simultaneously. The H100 can be partitioned into multiple instances as opposed to the A100, making it more scalable for large-scale deployments. Let’s have a look at the landscape of GPU architectures designed for inference tasks. When evaluating options, we encounter several prominent contenders:
Cost is another consideration when selecting a GPU. The cost will depend on the features and performance we’re looking for. Although the H100 is the cutting edge of current technology, it’s also the most expensive system designed for enterprise-level applications. Let’s see how the cost behave for different GPUs based on their use cases and target audiences:
The GPU we choose depends on the workload, budget, and scalability required.GPUs can perform differently depending on the specific model type and the nature of the tasks being executed. Consequently, it’s essential to match the GPU with our project needs.
NVIDIA H100 is designed for large enterprises, research institutes, and cloud providers. These organizations would benefit from its performance to train massive AI models or perform high-performance computing. It offers the largest selection of modern AI techniques, with the additional features required for training machine learning models,inference, and data analytics tasks.
For any organization that doesn’t need bleeding-edge performance, the A100 is a great choice. It’s fast for AI training or inference workloads that benefit from multi-instance GPU (MIG) technologies. This enables the partitioning of resources for multiple users. It’s well-suited to an environment that maximizes efficiency, such as cloud environments.
For a moderate workload, the NVIDIA V100 GPU is a cost-effective solution that can get the task done. It’s not as powerful as the H100 or the A100, but it still delivers enough performance at a lower price point.
The RTX 4090 is best suited for developers, researchers, or small organizations that need a powerful GPU for AI prototyping, small-scale model training, or inference. It offers impressive performance for its price, making it an excellent choice for those working on a budget.
Let’s consider a table summarizing the GPU selection based on workload, budget, and scalability:
GPU Model | Best Suited For | Key Features | Use Case |
---|---|---|---|
H100 | Large enterprises and research institutions | Best for large-scale AI tasks and data analytics | Advanced AI research, large-scale model training, inference |
A100 | Cloud environments and multi-user setups | Fast AI training, supports resource partitioning (MIG) | Cloud-based AI tasks, multi-user environments, efficient resource usage |
V100 | Moderate workloads and smaller budgets | Cost-effective, handles AI training and inference | AI model training and inference for moderate-sized projects |
RTX 4090 | Developers, small organizations | Affordable, great for AI prototyping and small-scale tasks | AI prototyping, small-scale model training, research on a budget |
This table highlights each GPU’s ideal use case, key features, and applicable scenarios.
Choosing the right GPU is especially important in the fast-moving world of AI and machine learning since it impacts the productivity and scalability of the model. The NVIDIA H100 is a great choice for organizations on the cutting edge of AI research and high-performance computing.
However, depending on our needs, other options like the A100, V100, or even the consumer-grade RTX 4090 can deliver strong performance at a lower cost.
By carefully examining our machine learning workloads and analyzing the strengths of each GPU, we can make an informed decision. This will ensure the best combination of performance, scalability, and budget.
