Best GPUs for Machine Learning
Learn more about GPUs and what you specifically need for your machine/deep learning task.
Machine learning and deep learning are fields that require intense computational requirements to be able to produce high-performance models and accurate outputs. The GPU you choose to work with has a big impact on your machine learning and deep learning experience.
The training phase in the machine and deep learning process take up the majority of the pipeline. The most valuable phase of the pipeline is when the data scientists, machine learning engineers, and other data professionals can start to work on fine-tuning the model to make it robust. However, these data professionals are often waiting around for the training to be complete, affecting their productivity, time, resources and money.
People are always looking for new ways to improve their current process, speed it up, or automate it purely. The adoption of GPUs into your process will enable you to perform AI computing operations in parallel.
But how do you know which GPU to use? What GPU features should be important to your machine learning task? Will it reduce the overall cost, or increase it? Why do I want to invest in a GPU in the first place?
This blog will go through these questions, taking you to the beginning on what GPUs are, how they work, the best on the market, NVIDIA GPU specs, use cases, and more.
But before we get into the specifics of the GPUs, and the different ones in which we will compare. I am going to introduce you to the basics of artificial intelligence and machine learning, ensuring all the pieces of the puzzle fit nicely. Understanding the basics of machine learning and its process will give you a better grasp of why GPUs are important, and in which stage they will be working their hardest.
What is Machine Learning?

Machine Learning belongs under Artificial Intelligence, the ability of a computer or a computer-controlled robot to perform tasks that are usually done by humans as they require human intelligence.
Machine Learning is the process of allowing models to learn and improve using past experience by exploring the data and identifying patterns with little human intervention. Today we currently work with 4 different types of machine learning: Supervised Learning, Unsupervised Learning, Semi-Supervised Learning and Reinforcement Learning.
Supervised Learning is when an algorithm learns using a labeled dataset and analyzes the training data based on its knowledge learnt using the labeled dataset. These labeled data sets have inputs and expected outputs.
Unsupervised Learning learns on unlabeled data, therefore it requires the model to infer more about the hidden structures of the data in order to produce accurate and reliable outputs.
Semi-supervised learning is a combination of supervised and unsupervised learning. It uses labeled data to make predictions, and unlabeled data to learn the shape of the larger data distribution.
Reinforcement Learning is the training of machine learning models to make a sequence of decisions and focuses on learning the optimal behavior in an environment to obtain the maximum reward. It is considered the science of decision-making.
Machine Learning Process:
So what does the machine learning process look like? Let’s go through the 7 steps of Machine Learning.

Your data collection is based on the problem or task you are trying to solve. Your data can be pre-collected, or collected by yourself. An important aspect to remember is that the quantity and quality of your data dictate how accurate your model turns out.
Once you have collected your data, you will need to prepare it in the correct format for it to undergo analysis. This includes cleaning the data, randomizing data, and preparing it for the training phase. You can also create visualizations of the data to give you a better understanding of relevant relationships between variables or class imbalances. You will then split that data into training and evaluation sets, before inputting it into the model.
Choose the Model
Depending on the task at hand, different algorithms are used for different tasks. Therefore, you will need to have an in-depth understanding of what you are trying to solve and what you want your expected output to show.
Training the Model
We all need to learn in order to be proficient in a subject. The same goes for machine learning models – they undergo a training phase which helps them learn about the data, the relationships, and specific variables. The goal of the training phase is for the model to be able to answer a question or make predictions correctly and effectively.
Evaluating the Model
Once the model has made predictions based on the training data, you will need to evaluate its performance. This can be achieved by using performance metrics such as Accuracy, Recall, Precision, and F1- Score. You can also test your model against unseen data to see how effective the training phase works on data the model has not seen before.
At this point, you will understand the limitations of your machine-learning model and will want to improve its performance. Hyperparameter tuning is the process of tuning the model’s parameters for improved performance. The goal is to maximize model performance, whilst being able to minimize a predefined loss function in order to produce better results with fewer errors.
Your next step would be to test your machine learning model by using test data, where the class labels are known and can give us a better approximation of how the model will perform in the real world.
What are GPUs?
Image by Author
GPU stand for Graphics Processing Unit, and they are built into your device to accelerate graphics and image processing. They are made up of thousands of smaller cores that are designed to work in parallel, allowing them to perform tasks simultaneously and much faster than the CPU.
GPUs are located on graphics cards, which are then plugged into a computer’s motherboard. GPUs are an important element in modern computing, with them constantly evolving to become more powerful to meet the current and future market in computing and technology.
Some newer CPUs have integrated GPUs, allowing them to have specific features and functionality of a graphics card built into the CPU. When it comes to working with machine learning in particular, CPUs unfortunately cannot handle the processing of large data in parallel, the same way GPUs can.
Parallel processing is the method that helps GPUs to function. It is when multiple processors handle separate parts of the same task, allowing the performance of many calculations at the same time.
GPUs have helped to improve a wide range of applications, such as artificial intelligence, scientific computing, graphics and video rendering.
Due to their ability to handle multiple tasks at the same time, GPUs are more energy-efficient than CPUs that can only handle one at a time.
How do GPUs work?
GPUs are made up of thousands of small processing units called cores, where each core can perform a single instruction at a time in a very fast manner. This is how GPUs can deal with computationally intensive tasks and complete them effectively.
As you can imagine, with all the data and tasks GPUs process within a few seconds, they require a large amount of memory to store data and other information that they need to process. Due to the type of tasks that GPUs deal with, they will typically have a much faster memory than a CPU in order to access the stored data quickly.
The generic overview of the GPU process starts with Loading the data -> Processing the data -> Dividing and assigning each part to a different core -> Cores working in parallel -> Send the results back to the memory.
Why GPUs are Important for Machine Learning and Deep Learning
Machine learning and deep learning consist of a lot of complex computing tasks, for example, computer vision, natural language processing, training deep neural networks, mathematical modelling, 3D graphics, and more.
When it comes to machine and deep learning, the most intensive phase in the pipeline is the training phase. The training phase is where your machine learning models digest the prepared data and learn more about the data, find patterns, and make predictions. Machine learning and deep learning algorithms are typically trained on very large datasets, in which the model needs to learn every aspect of the data so that it can accurately complete future predictions and tasks.
This will require a lot of computing power, in order to deal with large volumes of datasets that need mathematical calculations performed in a short period of time. With anything in life, practice makes perfect. The same goes for machine learning models, the more training the model goes through, the better it gets at making predictions.
Therefore, as you increase your training data, the training time will increase with your resources being used up – which can all become very expensive. However, with the use of GPUs, you can run machine learning models with massive numbers of parameters, and complex tasks quickly and effectively.
High Performance and Accuracy
In order for these applications to be able to produce high-performing, accurate outputs – it requires a reasonably powerful GPU. CPUs unfortunately don’t have the high processing power, cores, and memory to handle the complex tasks like GPUs do.
By being able to distribute tasks GPU features help focus on tasks and free your CPUs for other tasks, improving compute capabilities. GPU’s high performance and energy efficiency benefits are becoming more popular as technology continues to grow.
Computational-intensive tasks can use GPU clusters to work on a single task together. A GPU cluster is a group of GPUs connected and made up of multiple nodes, which contain either one or more GPUs. The nodes are connected to high-speed networks, such as InfiniBand or Ethernet.
A GPU cluster aims to take a task and divide it up into multiple sub-tasks that can be executed on different GPUs parallelly. GPU clusters are much faster than using a single GPU, and that’s why it’s very popular with deep learning training.
AMD vs NVIDIA
Typically you’ve probably heard about AMD GPUs and NVIDIA GPUs. But what’s the difference between the two? And which one is better for machine learning and deep learning tasks?
AMD stands for Advanced Micro Devices and is produced by Radeon Technologies Group. Graphics cards are important in allowing your PC to be able to display videos, pictures, and other graphics. AMDs are popular due to their offering a powerful value based on their price and a user-friendly interface. They are powerful graphic cards, however, they are not considered as powerful as Nvidia GPUs.
AMD and NVIDIA are the most widely used GPUs on the market at the moment, and due to this, they have had a back-and-forth ongoing battle for GPU supremacy. The two offer a wide range of products, at different prices.
Due to AMD being more in the affordable and comfortable range, they benefit and remain highly competitive. However, NVIDIA works with higher-end GPUs which are valued at a price for customers who need to work with specific features and a level of performance, and can simply afford it.
When you’re looking at GPUs that need to work effectively on machine learning and deep learning tasks, you will steer more towards the GPUs with more features and have a higher level of performance. NVIDIA GPUs offer that, making them very popular in the world of artificial intelligence.
Important GPU Specs for NVIDIA Cards
When looking into NVIDIA GPUs for machine learning and deep learning processes, you need to look at the must-need GPU specs. Your tasks will be more computationally intensive, and require more power and storage.
Processing cores are responsible for processing all the data that is fed into and out of the GPU. If you are using an AMD GPU, these processing cores are called AMD stream processors.
CUDA cores are solely for NVIDIA GPUs and are the processors that accelerate the execution of parallel computing. They are made up of smaller units called arithmetic logic units (ALUs) and memory access units (MMUs), and it is these units that optimize parallel processing.
The more CUDA cores a GPU has, the more it can perform multiple calculations at the same time, and perform these tasks faster. CUDA cores provide GPUs with the main capabilities why GPUs are very popular for machine learning and deep learning tasks.
CUDA cores can:
- Perform at high speed
- Provide efficient parallel processing
- Be a cost-effective alternative to computationally intensive tasks
CUDA cores specialize in parallel computing, whereas Tensor cores are more specialized processors to work with deep learning and AI workloads. Tensor cores allow for mixed-precision computing, adapting calculations dynamically, and improving and maintaining accuracy.
When working with machine learning and deep learning models, you will be working with large datasets. In order for your GPU to handle these large amounts of data, it needs memory bandwidth. Memory bandwidth is the amount of data a GPU can read or write from its memory per second. The higher the memory bandwidth, the faster the GPU can process data.
The data that the GPU can read or write from is stored. GPU memory is the amount of storage space available for the GPU to store data securely. If you are working on models such as large language models, you will need to use a lot of datasets to produce a high-performance machine learning mode. But at the same time, you will also require high GPU memory to store the data.
Use Case 1: Stable Diffusion
To give you a better understanding of GPU applications, let’s talk about stable diffusion.
What is Stable Diffusion?
Stable Diffusion is a type of diffusion model, called Latent Diffusion Model, and is the open-source alternative to DALL-E 2. The latent Diffusion Model is a machine learning model that is designed to learn the underlying structure of a dataset by mapping it to a lower-dimensional latent space. Latent diffusion models are a type of deep generative neural network, which was developed by the CompVis group at LMU Munich and Runway.
Stable diffusion is a text-to-image model, which was released in 2022. The model can generate detailed images based on text descriptions, as well as inpainting, outpainting, and more. The stable diffusion model has been trained on a large dataset of images and texts and has been used to create a wide variety of images.
How does Stable Diffusion Work?
Image by Author
Stable Diffusion starts off by first compressing the image into a latent space, which is a much smaller dimensional space than the actual image space. Stable diffusion is achieved by using a technique called the variational autoencoder, a neural network that has two parts: an encoder and a decoder. The role of the encoder is to compress the image into a lower dimensional representation in the latent space whilst the role of the decoder is to restore the image from the latent space. Although it will be compressed, it still contains all the qualities and information of the actual image.
The diffusion process is when you slowly add or diffuse noise to the compressed latent representation, and generate an image that is just noise. However, the diffusion model goes in the opposite direction and does the reverse process of diffusion. The noise is gradually reduced from the image in a controlled way, so the image slowly appears to look like the original.
This is done using U-Net architecture, a convolution-based neural network that can do image localisation by predicting the image pixel by pixel. This is how stable diffusion generates realistic and very detailed images.
In order for Stable Diffusion to run effectively, you will need:
- 16GB of RAM
- Nvidia graphics card with at least 10GB of VRAM
Real-world applications of Stable Diffusion
Here is a list of real-world applications of Stable Diffusion:
- Art creation, such as photos of real-world objects, real-like paintings, imaginary landscapes, abstract art, and more.
- Product design
Use Case 2: Large Language Models
What are Large Language Models?
Large Language Model (LLM) is a currently popular deep-learning algorithm consisting of a neural network, giving the model the ability to read, recognise, summarize, translate, predict and generate text. They are a type of transformer model, a neural network that learns context by tracking relationships in sequential data.
They require to be trained on large amounts of text data to be able to successfully generate accurate outputs. Predicting future words and constructing a sentence allows the model to better understand how humans talk and write and be able to have conversations – just like humans!
You may have heard of the popular ones ChatGPT and Google Bard.
How do Large Language Models work?
Image by Author
As we can assume from its name, Large Language Models (LLMs) need large amounts of data to be trained on. For example, if you’ve had a chance to trial ChatGPT and Google Bard, it’s quite amazing how the applications can answer the majority of your queries, with a few limitations. This is down to the variety of data sources, such as books, articles, websites, and social media that were used as training data for the model.
Large language models are types of transformer models, a neural network that learns context and tracks the relationships in sequential data, for example, words in a sentence. They use mathematical techniques called attention or self-attention, where attention is when a transformer model attends to different parts of another sequence, whereas self-attention is when a transformer model attends to different parts of the same input sequence.
LLMs use unsupervised learning, where the model learns on unlabeled data, more about the hidden structures and the construction of sentences and relationships between the words. Along with LLMs learning context by tracking relationships in sequential data, LLMs can predict the next word in a sentence by analyzing the words that came before it. The unsupervised learning and transformer model features help the LLM to learn more about language, context, grammar, and tone of language.
Looking at GPT-3, it’s a 175 billion-parameter language model that focuses purely on language and has an in-depth understanding of the written and spoken word. That is a lot of data, and a model this large would have required high computational power, high memory bandwidth, and a lot of memory. In order for GPT-3 to be successful, the company stated that:
“The precise architectural parameters for each model are chosen based on computational efficiency and load-balancing in the layout of models across GPUs. All models were trained on NVIDIA V100 GPUs on part of a high-bandwidth cluster provided by Microsoft”
Real-world applications of LLM:
- Chatbots: Powering chatbots such as ChatGPT and Google Bard AI that can have conversations with humans, by answering questions, providing customer service, and generating content.
- Virtual assistants: LLMs are used to power virtual assistants such as Siri and Alexa. They can understand and respond to natural language, as well as handle tasks.
- Translation: You can use LLMs to translate text from one language to another.
- Content generation: LLMs can generate text in different types of content, such as blog posts, product descriptions, poems, songs, and marketing materials.
