Initially, GPUs were created to process data from a central processor and render images for display. But modern GPUs? They do far more than just image rendering. Today’s GPUs handle complex 2D and 3D graphics in real-time and deliver far smoother frame rates and higher resolution.

As technology advanced, GPUs became essential for tasks like 3D modeling, CAD drawings, video editing, and special effects in movies. With the rise of AI, GPUs evolved to power machine learning. Imagine building a model that can diagnose a complex medical condition in minutes.

For instance, a data scientist might spend weeks compiling data to create a deep-learning model that identifies cancer signs. While promising, these models can often fail—crashing or lagging—because traditional CPUs can’t handle the enormous data loads and complexity.

This is one of the biggest challenges in deep learning: the training phase. A model must learn from millions of images while maintaining performance. This is where GPU colocation becomes invaluable. By using colocation services, businesses, and researchers access powerful GPUs in top-tier data centers without the cost of building their own infrastructure. This setup simplifies handling massive datasets and accelerates breakthroughs in science and technology.

As data volumes grow and machine learning becomes more complex, the demand for faster, more powerful GPUs increases daily. This blog will take a deep dive into the world of GPUs being used for deep learning, the factors to consider when buying one, and a detailed analysis of what GPU performs the best under extreme amounts of datasets. It will also equip you with the information you need to choose the right GPU for your machine-learning system. 

Why Are GPUs Important for Machine Learning? 

Deep learning involves large datasets and complex calculations. While a CPU can run the software needed for these tasks, it’s not designed to handle concurrent and highly complex computations efficiently. This is where a powerful GPU comes in to support the CPU by managing these demanding processes.

GPUs are super important for deep learning because they handle big datasets and do lots of tasks at once. The role and purpose of data center GPUs is to take on heavy-duty jobs, like training AI models and processing massive amounts of data, making them perfect for advanced machine learning.

Think of a GPU as the heart of your deep-learning project. It’s a specialized piece of hardware that works alongside your CPU, handling the heavy calculations. By doing so, it drastically reduces the time required to train your deep-learning model.

This capability allows businesses to: 

  • Target new opportunities: With a faster deep learning model, businesses can analyze data and deploy solutions much quicker. This speed allows them to explore emerging trends and capitalize on new opportunities, whether it’s launching innovative products, improving customer experiences, or optimizing internal operations. For example, companies using advanced GPUs can train AI models in hours instead of weeks so they can act on real-time insights and stay ahead of the competition.

  • Improved efficiency: A CPU handles all complex tasks, but it needs a GPU to function efficiently. For instance, Airbnb may use CPUs to handle user interactions but relies on GPUs for image recognition systems. This separation of tasks enhances efficiency across the platform.
  • Improved accuracy: A powerful GPU means a business can improve its deep learning system alongside AI, and provide it with more datasets that will lead to accurate calculations and an efficient system. For example, Paypal has 426 million users but how is it perfectly secure from fraudulent activities? Paypal uses a GPU for its deep learning system, this GPU functions to analyze large amounts of data being fed into it to secure its platform from fraudulent activities in real-time.
  • Increased security:  Given that a GPU is 100 times faster than a CPU, this allows businesses to push the boundaries of their deep learning systems, leading to new products, faster services, and a secure platform for millions of users. When you talk about a secure learning system, Tesla is the one to look at. Tesla uses GPUs to continuously improve real-world driving experiences, given that most of its cars are electric and feature AI-powered systems, including lane assist, cruise control, and self-driving capabilities.
  • Scalability and cost-effectiveness: GPUs allow businesses to scale their deep learning systems as data grows, without massive increases in infrastructure costs. Cloud-based solutions and GPU colocation services enable companies to access high-powered GPUs without purchasing expensive hardware. 

CPU vs GPU for Machine Learning 

To understand why GPU excels in machine learning over CPU, we need to look at the basics of how they function:

  • CPUs: These are designed for sequential tasks, focusing on accuracy. Think of them as the brain, solving one problem at a time. However, they fall short when it comes to handling multiple tasks in parallel.
  • GPUs: These excel in parallel processing. They can handle massive datasets, complex calculations, and algorithm training which makes them ideal for machine learning.

So the conclusion is that a CPU is a central body that revolves around solving one task at a time, to handle that task a team is required, and that team is provided by a GPU, which can quickly take care of all the datasets, complex calculations and make efficient algorithms for AI machine learning side by side. 

GPU for AI – Deep Learning and Machine Learning 

CPU is efficient and powerful when it comes to solving sequential tasks, but they lag behind GPUs when it comes to performing parallel tasks with more efficiency. 

For a detailed review of GPU VS CPU, have a look at our guide, where we have carefully examined both CPU and GPUs ideal for an AI framework and why a CPU lags behind a GPU.

Here are some pros and cons for GPUs used for AI: 

Pros

Parallel processing: 

GPUs can execute thousands of tasks simultaneously, like image rendering, AI machine learning, or model training, making a GPU 10 times faster and more effective. Parallel processing is the reason why businesses turn to AI colocation, which is not only efficient but makes machine learning fast and reliable. 

If you want to keep your AI machine running at full speed, partner up with TRG where we provide the perfect solution to make your AI Machine learning successful. 

Specialized Cores: 

Unlike a CPU, A GPU consists of cores designed to perform 

  • CUDA Core: A CUDA Core is designed to perform parallel tasks alongside a CPU, look at it this way, the more CUDA cores your GPU has, The faster it performs.
  • Tensor Core: Every Machine learning or deep learning project has complex calculations, a Tensor core is specifically designed to target these calculations, and act as an integral part of your machine learning system.

Bandwidth: 

A CPU performing a single task at a time has low memory bandwidth, while a GPU has a High Memory Bandwidth. Memory Bandwidth is the rate at which data can be transferred from a GPU, think of it like a highway, the bigger it is the faster data travels. 

Adaptation to AI: 

Look, AI and Machine learning, both need large amounts of datasets to work with and a GPU having high bandwidth memory, specialized CUDA, and Tensor cores tends to adopt faster, leading to short-time training phase and quick results. 

Cons

Costly: 

GPUs that can handle machine learning are typically high-end GPUs, so they’re really expensive compared to CPUs

Energy Consumption: A GPU consumes far more energy than a CPU, the reason being; that a GPU is specialized to perform sequential operations, having specific cores for each operation; to handle this load,  a GPU consumes a lot of energy that produces heat, and a cooling system is needed 

Interconnection: Interconnecting GPUs can be a complex method, it requires specific knowledge to connect these GPUs in parallel 

The Best GPU for AI in 2024

Why Data Centers Are Important for Deep Learning

A Datacenter is essential for your deep learning system in many ways: 

  • Computational needs: A deep learning system needs a lot of power to train, and data centers house thousands of GPUs ready to handle that load. It’s like having an entire powerhouse working for your AI.
  • Storage capacity: Big projects mean big data, and storing all that information takes serious space. A proper data center gives you the infrastructure you need to keep everything running smoothly.
  • Power: GPUs are power-hungry and generate a ton of heat when they’re working hard. Data centers come with advanced cooling systems and enough energy to keep things cool and running without a hitch.
  • Scalability: Need to expand your operations as your projects grow? Data centers make scaling easy. You can start small and add resources as needed without breaking a sweat—or your budget.
  • Reliability: No one likes downtime. Data centers are built to keep things running 24/7, with backups for everything from power to cooling. It’s like having a safety net for your AI projects, so you never have to worry about interruptions.

Key Takeaways

Picking the right hardware for machine learning means knowing how GPUs and CPUs work together. GPUs take care of the heavy lifting, while the best CPU for AI keeps everything running smoothly and manages tasks efficiently.

GPUs have an advantage over CPUs, whether it is complex calculations, feeding, storing large datasets, or machine learning. With specialized CUDA and Tensor cores, and the ability to link to other GPUs with NVIDIA Link, they act as a driving force to your machine learning project. GPUs can perform millions of calculations side by side, with 3D image rendering, Image recognition, adaptation to AI, natural language selection, and training deep learning models which makes it far more efficient than a CPU. This ability makes it the core element of the future of AI. 

A high-performing GPU  compared to A100 PCIe, It features SXM4 which is ideal for high-end servers having SXM slots. It features 80 GB of HBM2 memory which provides an increase in memory bandwidth as compared to PCIe-based GPU. 

Here are some factors that affect GPU performance. A CUDA core is designed to perform tasks simultaneously, more CUDA cores means your GPU can process tasks at a higher speed. AI models often work with large amounts of datasets that need to be transferred quickly. A higher memory bandwidth means your GPU can transfer more data, so ensure your GPU has enough memory ( 48GB or more )  capacity for your machine learning system. 

If you want faster calculations, pick a GPU that has more tensor cores because they’re specialized to perform complex calculations that can help with the training phase and make your model quicker. 

Different AI models work best with GPUs tailored for them, here are a few examples . Top-tier GPUs like NVIDIA A100, NVIDIA H100, AMD INSTINCT MI250X, and AMD INSTINCT MI300A work best for deep learning models as they offer the highest performance that can cater to large datasets being used in Deep learning models. 

For more common AI applications like image detection, object identification, and natural language processing go for a GPU that provides efficiency with cost effectiveness, like NVIDIA A40.

The most compatible GPUs out there are CUDA-operated GPUs like NVIDIA A100 and NVIDIA H100. CUDA-operated GPUs are compatible with both TensorFlow and PyTorch libraries. NVIDIAs newest architecture, ampere, and Lovelace offer the best compatibility. AMD GPUs are supported by an open software called ROCm that allows it to connect to different libraries, most GPUs support PyTorch but are limited to TensorFlow Libraries.
