Factors to Consider to Find The Best GPU for Machine Learning
Here are a few things that you need to consider to find the best GPU cloud server for deep learning:
Licensing requirements for different GPUs are also different. For instance, as per the NVIDIA guidelines, some chips are prohibited for use in the data centers. As per the updates of licensing, for the use of consumers, CUDA software has certain limitations. Also, these licensing requirements require transition to the GPUs supported by production.
Interconnection of GPUs
The scalability of any project is highly dependent on the interconnecting GPUs. In addition, the interconnected GPUs decide whether or not more than one GPU and distribution strategies can be utilized. Interconnecting GPUs do not support consumer GPUs. For example, Infiniband connects various GPUs to different servers while NVlink connects multiple GPUs within a single server.
GPU usage is also affected by the training data memory requirements. To give an example, the algorithms having any medical imagery or long videos as their training data set need GPUs with more memory. In comparison, the basic training data sets will work efficiently with cloud GPUs having less memory.
Machine Learning Libraries
One needs to be aware of the different libraries used by various GPUs, and specific Machine Learning Libraries are supportive of some specific GPUs only. Thus, the choice of GPU highly depends on the Machine Learning Libraries in use. The NVIDIA GPU supports almost all the basic frameworks and MLLs like PyTorch and TensorFlow.
Performance of GPU
The model’s performance is also a factor looked for in selecting a GPU like the basic GPUs are utilized for debugging and development purposes. On the other hand, strong GPUs are utilized to speed up the training time and reduce the number of waiting hours.
GPU selection also depends on the size of data being used for processing. If the data set is vast, the GPU should be capable of working on multiple GPU training. In case the data set is more extensive than usual, the GPU should be able to enable distributed training, and it is so because, in this case, servers are required by the data sets for effective and speedy communication.
CUDA cores vs Tensor cores
CUDA cores and Tensor cores are specialized processors designed for different types of workloads. CUDA cores are optimized for general-purpose parallel computing tasks, while Tensor cores are specifically designed for deep learning and AI workloads. When choosing a GPU for AI and deep learning, it is important to consider whether the GPU has Tensor cores, which are specialized for deep learning workloads.
Single precision vs. Double precision
Single precision and double precision refer to the precision of the floating-point calculations that a GPU can perform. Single precision is faster and uses less memory, but it is less accurate than double precision. Double precision is slower and uses more memory, but it is more accurate. When choosing a GPU for deep learning, it is important to consider whether the accuracy of double precision is needed for the specific task.
Power consumption is another important factor to consider when choosing a GPU for deep learning. GPUs can consume a lot of power, especially when training large deep neural networks. It is important to consider the power consumption of the GPU and how it will impact the overall power usage and cost.
The price of a GPU is also an important factor to consider when choosing a GPU for deep learning. High-end GPUs can be very expensive and may not be necessary for all deep learning tasks. It is important to balance the cost of the GPU with the specific needs of the deep learning task.
When choosing a cloud GPU for deep learning, it is important to consider above-mentioned factors. All these factors will help you to determine the best GPU for the specific deep learning task and budget.
How to Optimize GPU Performance for Deep Learning

- Using GPU-enabled libraries: Many deep learning frameworks, such as TensorFlow and PyTorch, have built-in support for GPU acceleration. When using these frameworks, it is important to use the GPU-enabled version of the library in order to take advantage of the GPU’s computational power. Additionally, there are libraries like CUDA and cuDNN which are specifically optimized for GPU computation.
- Minimizing data transfer between CPU and GPU: Transferring data between the CPU and GPU can be time-consuming and slow down the training process. To minimize data transfer, it is important to ensure that the data being used is stored on the GPU memory. This can be achieved by using libraries like CuPy that copy the data to the GPU memory before computation.
- Batch size: The batch size is the number of samples used in one iteration of training. Increasing the batch size can improve the performance of the GPU. It is important to experiment with different batch sizes to find the optimal value for the specific deep learning task.
- Regularly monitoring GPU utilization: Monitoring the GPU utilization during training can help identify bottlenecks and inefficiencies in the deep learning process. This can be done using tools like nvidia-smi that provide detailed information about GPU utilization, memory usage, and other performance metrics.
In conclusion, choosing the best GPU for deep learning is an important step in ensuring that deep learning tasks are performed efficiently and effectively.
The progress of deep learning operations requires high computational power, and when compared with CPUs, GPUs deliver better processing power, parallelism, and memory bandwidth. Hence, GPUs are ideal for machine learning and deep learning tasks.
