The use of AI is on the rise, which means more demand for computing power. Everyone knows that having enough compute power is essential because, without it all the potential of AI remains unrealized. Using compute power efficiently is important to get the best performance while using the least amount of energy. There’s a lot of information about using GPUs for AI training, but not much on which GPUs are best for AI inferencing.
This article looks into the best GPUs for AI inferencing to help you save money and reduce time spent.
Why GPU over a CPU?
In AI inferencing, GPUs are favored over CPUs for a few key reasons.
Firstly, GPUs are built to handle many tasks at once while CPUs usually do one thing at a time. This means GPUs can crunch through the complex calculations needed for AI much faster. In other words, it’s good at parallel processing
AI often involves dealing with lots of data at once, like big matrices and tensors. GPUs are great at splitting up and dealing with this kind of data quickly because they have lots of cores working together.
On top of that, GPUs have special parts like Tensor Cores, specifically designed to speed up certain types of AI calculations. This gives them an extra boost when it comes to processing AI tasks.
Overall, GPUs are just better suited for the heavy lifting that AI requires. They can handle big jobs faster and more efficiently than CPUs, making them the go-to choice for AI inferencing tasks.
Considerations for Choosing a GPU for AI Tasks.
Choosing a GPU for AI training versus inferencing involves different considerations due to the distinct nature of these tasks.
AI Training Requirements:
- High Compute Power: Training deep learning models, especially large ones, demands significant computational resources to handle large datasets and complex calculations.
- Memory Capacity: High memory capacity (VRAM) is crucial for training, as it needs to accommodate large models and batches of data. Modern models can require tens of gigabytes of VRAM.
- Parallel Processing: A high number of CUDA cores (or equivalent) and tensor cores (in NVIDIA GPUs) are beneficial for the parallel processing of matrix operations.
AI Inferencing Requirements:
- Power Efficiency: Inferencing GPUs need to be power-efficient, especially for edge devices.
- Low Latency: Low latency is critical for real-time applications to ensure quick and efficient model predictions.
- Memory Optimization: While memory is still important, inferencing typically requires less VRAM compared to training, as the models are pre-trained and optimized.
- Integer Precision: Inferencing can often use lower precision, such as 8-bit integers (INT8), which allows for faster computations and reduced memory usage.
