Why Use GPUs for Deep Learning

GPUs are capable of doing many parallel computations. This facilitates the distribution of training processes, which can considerably accelerate deep learning tasks.

Parallel computing is a type of computation where a particular task is divided into smaller ones, each of which can be run at the same time. Large problems can often be divided into smaller ones, which can then be solved at the same time.

For example, think about how long it would take to count all the books in a library.

It’s a simple task, but if you did this by yourself, it would probably take you a long time. If you ask a few of your friends to help you, each person counts a single shelf or a single set of shelves.

So you’ve divided the task, and each person can work independently, and then your friends can ad the results and give you the final answer.

If our processing unit has numerous cores, we can divide our jobs into smaller ones and run them all at once. This will make better use of the processing power we have available and allow us to perform our duties much more quickly.

A CPU typically contains four, six, or eight cores, while a GPU contains hundreds or even thousands of cores. This makes GPUs much better at parallel computing than CPUs.

The Best GPUs for Deep Learning & Data Science 2022

When you’re using GPUs for deep learning, you have a few different options. You can choose between consumer-facing GPUs, professional-facing GPUs, or data center GPUs, depending on what you’re using them for.

  • Consumer GPUs: If you’re an individual, then consumer-grade GPUs are probably the best option for you. They’re the most popular choice, are less expensive, and they’re still powerful enough for most deep learning tasks. You’re not limited to using a single GPU, either – you can combine multiple GPUs to get even more computing power.
  • Professional GPUs: If you’re a professional, then you might want to consider a professional-grade GPU your deep learning applications. These are designed specifically for professional use, and they’re compatible with industry-leading applications. They’re also supported for years, so they’re seen as a long-term investment.
  • Data Center GPUs: Data center GPUs are the most powerful option for most deep learning applications, but they’re also the most expensive. If you’re working on something that requires a lot of computing power, like training large neural networks, then data center GPUs are the way to go.

Best Consumer GPUs for Deep Learning

While there are a number of different types of GPUs on the market, consumer-facing GPUs are the ones that are most commonly used by gamers and other consumers. These GPUs are typically designed to be more affordable and offer a balance of performance and power efficiency.

How to Choose the Best GPU for Deep Learning?

When choosing a GPU for deep learning, there are some important factors you have to consider.

1. NVIDIA Instead of AMD

If you want to buy a GPU for deep learning, you should get an NVIDIA GPU.

AMD GPUs are not as good as NVIDIA GPUs for deep learning because they don’t have Tensor Cores or the equivalent, which means they can’t do mixed-precision deep learning training.

In addition to that, ROCm, which is like “CUDA” for AMD GPUs, doesn’t have as good of a software ecosystem as CUDA does. This means that you won’t have as many options when it comes to deep learning frameworks, libraries, and tools. The community around ROCm may be growing, but it’s still not as good as the CUDA community.

2. Memory Bandwidth

Memory bandwidth is the rate at which data can be read from or written to a memory device.

GPUs typically have a high memory bandwidth because they need to be able to process large amounts of data quickly. The amount of data that a GPU can process in a given time is determined by its memory bandwidth.

The term “memory bandwidth” is often used interchangeably with “memory speed.” However, memory speed is a measure of how fast data can be transferred between the memory and the CPU, while memory bandwidth is a measure of how much data can be transferred in a given period of time.

Memory bandwidth is important for GPUs because they need to be able to process large amounts of data quickly. The amount of data that a GPU can process in a given time is determined by its memory bandwidth.

Imagine that the Tensor Cores have already computed the results of an operation, and now they’re idle, waiting for data to arrive from memory. If the memory bandwidth is low, the Tensor Cores will have to wait a long time for data to arrive, and this will slow down the overall performance of the GPU.

On the other hand, if memory bandwidth is high, the Tensor Cores will be able to keep working, and the GPU will be able to operate at its full potential.

Memory bandwidth is, therefore, a key factor in determining GPU performance

3. GPU Memory (VRAM)

VRAM (Video RAM) is a type of computer memory that is used to store graphics data. It’s like RAM (random access memory), but it’s the GPU memory, specifically designed for use with graphics data.

When it comes to GPUs, VRAM is used to store the image data that is being rendered by the GPU. The more VRAM a GPU has, the more data it can store and the better it can handle demanding graphics workloads.

For deep learning practitioners, VRAM is an important consideration when choosing a GPU. Higher GPU memory will be able to handle larger datasets and train neural networks more quickly. When training deep learning models, it is often beneficial to use a GPU with as much VRAM as possible.

This depends on the size of the dataset, the complexity of the neural network, and the desired training speed. For small datasets and simple neural networks, a GPU with 4GB of VRAM may be sufficient. For larger datasets and more complex neural networks, a GPU with a minimum of 8GB VRAM is often recommended.

Again, the amount of GPU memory needed depends on the size of the dataset and the complexity of the neural network. For deep learning practitioners, it is important to choose a GPU with enough VRAM to meet their needs.

A sweet spot for VRAM in deep learning is 12-16GB (preferably 16GB). Even if a GPU has fewer CUDA cores, which means the GPU is slower, if it has more VRAM, it’s probably better to go for more VRAM.

You can tweak and optimize your code for lower VRAM usage. However, you’ll have to know what you’re doing.

In general, we want as many CUDA cores as we can get and as much VRAM as we can get, however, if you don’t know how to optimize your code, more VRAM is always better.

4. Tensor Cores

In a nutshell, Tensor Cores are special hardware units designed to speed up deep learning tasks. They’re available on select Nvidia GPUs, and they can provide a significant performance boost on supported machine learning workloads.

If you’re a deep learning practitioner, you’re probably already familiar with the benefits of using a GPU for training and inference. GPUs are well-suited for deep learning because they can perform many parallel computations. This parallelism makes training deep neural networks much faster on a GPU than on a CPU.

Tensor Cores take this parallelism to the next level by allowing even more computations to be performed in parallel. This makes training deep neural networks even faster on a GPU with Tensor Cores. In addition, Tensor Cores can also speed up inference, which is the process of using a trained model to make predictions on new data.

Tensor Cores have been available since the Volta architecture was introduced in 2017. Volta-based GPUs such as the Titan V and Nvidia Tesla V100 are the first GPUs with Tensor Cores. Ever since then, Tensor Cores have become increasingly popular, and they’re now available on a number of different Nvidia GPUs.

5. CUDA Cores

These are the cores that are used to process information in a GPU.

To put it simply, the more cores a GPU has, the more information it can process at once. This is important for deep learning practitioners because the more cores a GPU has, the faster it can train a deep learning model.

A CUDA core is essentially a very fast and powerful processing unit. It can execute certain instructions much faster than a CPU. This is because a CUDA core is designed specifically for parallel computing.

Parallel computing is well suited for tasks that can be divided into smaller subtasks that can be executed simultaneously. This is because each CUDA core can execute a subtask independently. Neural networks are a good example of a task that can be parallelized.

Neural networks are also known to be embarrassingly parallel. This is because they can be easily divided into smaller tasks that can be executed in parallel. This is one of the reasons why GPUs are so well suited for training neural networks. Many computations in a neural network can be easily broken down into smaller tasks that can be executed in parallel.

6. L1 Cache / Shared Memory

GPUs with larger L1 caches can help improve data processing performance by making data more accessible.

L1 caches are used to store data that is frequently used by the GPU. By having a larger L1 cache, the GPU can access the data more quickly, which can give a performance boost. GPUs with Ampere architecture have a larger L1 cache than previous generations, which helps to improve GPU performance.

7. Interconnectivity

If you’re working on a big deep learning project that uses a lot of GPU-enabled servers to do lots of computations, you might need to set up a multi-GPU system. This is where you link multiple GPUs together so they can work together to speed up the computations. However, not all GPUs are compatible with each other, so it’s important to choose the right ones that will work well together.

When you’re setting up a deep learning workstation that includes multiple GPUs, there are a few things you need to keep in mind.

First, the motherboard needs to be able to support multiple cards. Second, the power supply needs to be strong enough to power multiple GPUs. Finally, data centers need to be able to support a high number of GPUs.

If you intend to use a setup with multiple GPUs for machine learning, make sure your hardware can handle it.

8. FLOPs (Floating Operations Per Second)

FLOPs, or Floating Operations Per Second, are a measure of a GPU’s computational power. They’re often used to compare different GPUs to see which one will be better for a particular task.

An example of a FLOP would be a multiplication operation. For example, if we have two numbers, say 2 and 3, and we want to multiply them, we would say that the operation is done in one FLOP. So, a processor that can do 10 FLOPs per second can do 10 multiplications per second.

The higher the number of FLOPs, the more powerful the GPU. So if you’re looking for a GPU that can handle a particularly demanding deep learning task, you’ll want to look for one with a high FLOPs rating.

TFLOP, which stands for teraflop, refers to a processor’s ability to perform one trillion floating point operations per second. For instance, “6 TFLOPs” denote that the processing layout can perform 6 trillion floating point computations per second on average.

Of course, FLOPs aren’t the only thing to consider when choosing a GPU. But if you’re looking for raw computational power, they’re a good place to start.

9. General GPU Considerations & Compatibility

Aside from the deep learning-specific requirements, there are a few general things you need to take into consideration when choosing a GPU for deep learning.

TDP (Thermal Design Power): The first thing you need to do when choosing a GPU is to find out the TDP of your graphics card. The TDP is the maximum power that the card can consume, and it is important to know because it will help you determine how much power your card will need. You can find the TDP of your card by looking at the specs of the card or by searching for it online.

Deep learning workstations need more powerful hardware than average desktops due to the complex nature of deep learning applications. Furthermore, training deep learning models takes a long time and requires a lot of computing power.

As such, make sure your PSU has enough capacity to handle your deep learning workstation.

Cooling: Another important factor to consider when choosing a GPU is the cooling of the card. You want to make sure that the card you choose has adequate cooling because if it doesn’t, your card will overheat and potentially break down.

There are many different types of cooling systems, so you will want to research the different types and find the one that is best for your needs.

Form Factor: The form factor of your GPU is also important to consider. The form factor is the size of the card and slot type. You want to make sure that the card you choose is compatible with your motherboard and case.

The size of the card is important because you need to make sure that your case can fit the card, and the slot type is important because you need to make sure that your motherboard can accommodate the card.

CPU Compatibility: The CPU you choose should also be compatible with the GPU you choose. You want to make sure that the two are compatible so that you can get the best performance out of your system and avoid any potential bottlenecking.

Frequently Asked Questions

How Much GPU Memory Do I Need for Deep Learning?

This is a difficult question to answer. It depends on the size of the models you are training and the amount of data you have. A good rule of thumb is that you need at least 12GB of GPU memory for training most modern deep learning models. If you’re just getting started with deep learning, you can get away with using a GPU with 6GB of memory.

However, if you want to train large models or use very large datasets, you will need to use a GPU with at least 16GB of memory.

Can I Use an AMD GPU for Deep Learning?

You can use an AMD GPU for deep learning, but you will need to use the open-source ROCm platform. ROCm (Radeon Open Compute Platform) is a platform for GPU computing that is compatible with a variety of AMD GPUs.

However, ROCm is not as widely supported as CUDA, so you may have a harder time finding software that is compatible with it.

Why Use a GPU vs A CPU for Deep Learning?

GPUs are typically much faster than CPUs when it comes to deep learning. This is because GPUs are designed for parallel computing, while CPUs are designed for sequential computing.

GPUs have thousands of cores that can work on different parts of a computation at the same time, while a CPU has only a few cores. Even though the CPU is great at many computations, it is not as good at parallel computations.

Does GPU Matter for Deep Learning?

GPUs are important for deep learning because they allow us to train deep neural networks much faster than we could using a CPU. GPUs are designed for parallel computing, which is perfect for deep learning. GPUs can greatly speed up the training of deep neural networks.

What Is the Best Value GPU for Deep Learning?

The best value GPU for deep learning is the arguably the NVIDIA RTX 3080 (12 GB). This GPU provides excellent performance for deep learning at a relatively affordable price.

What Is the Best Budget GPU for Deep Learning?

The best budget GPU for deep learning is the NVIDIA RTX 3060 (12 GB). It’s a great budget GPU because it comes at a lower price point than some of the other RTX 3000 series GPUs, but it still offers excellent GPU performance for deep learning, with 12GB VRAM.

What Is the Cheapest GPU for Deep Learning?
