Graphics Processing Units (GPUs) are an important component in deep learning as they are designed to perform the complex mathematical calculations required to train deep neural networks. They are able to perform these calculations much faster than traditional Central Processing Units (CPUs), which makes them essential for running large-scale deep learning models.

Deep learning models typically involve a large number of matrix operations, which can be parallelized and executed much faster on a GPU than on a CPU. Additionally, many deep learning frameworks like TensorFlow, PyTorch, and Caffe, have built-in support for GPU acceleration, making it easy for developers to use GPUs for deep learning tasks.

In short, GPUs are essential for deep learning as they provide the necessary computational power and speed to train large deep neural networks, allowing for faster and more accurate results.

What Are the Types of GPUs?

There are two main types of GPUs available CUDA cores and Tensor cores.

  1. CUDA Cores – CUDA cores are specialized processors designed for general-purpose parallel computing tasks. They are used for a wide range of workloads, including gaming, video editing, and scientific simulations. CUDA cores are available on both Nvidia and AMD GPUs.
  2. Tensor Cores – Tensor cores, on the other hand, are specialized processors designed specifically for deep learning and AI workloads. They are optimized to perform large matrix operations, which are commonly used in deep learning tasks such as image recognition, natural language processing and deep neural networks. Tensor cores are only available on Nvidia GPUs.

The main difference between CUDA cores and Tensor cores is their optimization. CUDA cores are optimized for a wide range of parallel computing tasks, while Tensor cores are specifically designed to accelerate deep learning and AI workloads that involve large matrix operations.

CUDA cores are general-purpose parallel computing processor, while Tensor cores are specialized for deep learning and AI workloads, which are optimized for matrix operations.

Why Should You Use GPU for Deep Learning?

In deep learning implementation, the training phase is the most extensive and resource-heavy phase. Though this phase can quickly be completed in less time if the models have fewer parameters, when this number increases, the time involved in training gradually increases. Thus, resulting in double expenditure.

With GPUs, you can successfully reduce these expenditures, allowing you to work with models with multiple parameters quickly and efficiently. GPUs can deliver such performance because it gives the liberty of conducting the training tasks parallelly and distributing tasks over groups of processors while performing computational operations.

In addition, GPUs are also used for performing computational and target tasks, which is a tough nut to crack for non-specific hardware. Thus, the bottlenecks occurring because of computation limitations no longer exist.

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.

Memory Usage

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.

Data Parallelism

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

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.
