5 best and most cost-effective deep learning GPU systems

Deep learning is transforming industries and creating new possibilities in healthcare, finance, entertainment, and many more. However, deep learning algorithms require powerful hardware to run efficiently and effectively. Access to hardware is essential for the smooth training of complex neural networks.

Graphical Processing Units (GPUs) have emerged as the backbone of deep learning systems, surpassing the capabilities of Central Processing Units (CPUs) due to their parallel processing capabilities. However, this comes at a premium because GPUs are pricey. This article will help you understand how GPUs work and identify the top five cost-effective ones for deep learning.

What is Deep Learning?

Deep learning is a subset of machine learning that employs algorithms to model high-level abstractions in data. This method is based on the structure and function of the brain, often referred to as artificial neural networks. Deep learning simulates how our brain works, enabling systems to learn, identify objects, and perform complex tasks with increasing accuracy without human intervention. This machine-learning technique teaches computers to do what comes naturally to humans: learn by example.

Deep learning can automatically learn and improve from experience, examining algorithms and adjusting them for better performance. It's a powerful tool in artificial intelligence (AI), imitating how humans gain specific knowledge.

What is GPU for Deep Learning?

As previously discussed, GPUs are electronic circuits specialised in manipulating and altering memory at high speeds to speed up image creation in a frame buffer intended to be displayed on a device. GPUs have been repurposed in deep learning due to their ability to perform multiple, simultaneous computations.

The parallel architecture of GPUs makes them exceptionally well-suited for intensive computation tasks like deep learning. They excel at executing matrix operations and performing multiple calculations simultaneously, which are fundamental in training neural networks—making GPUs indispensable tools for deep learning.

How do GPUs for Deep Learning Work?

Single Instruction Multiple Data (SIMD) Stream Architecture is widely used in GPUs today. This design enables them to perform parallel operations and perform more efficiently for specific tasks. When training a deep learning model, the model's parameters are updated using gradient descent optimization algorithms, which involve numerous matrix calculations.

The parallel processing capability of GPUs is beneficial for deep learning tasks, as they require extensive computations on large amounts of data. GPUs excel at performing these matrix operations in parallel, resulting in a substantial speedup in training times.

GPU-accelerated deep learning frameworks offer flexibility to design and train custom deep neural networks. These frameworks provide interfaces to commonly used programming languages, making it easier for developers to leverage the power of GPUs.

How to Choose the Best GPU for Deep Learning

Choosing the right GPU for deep learning involves considering several factors; the size of the GPU memory is critical as it determines the size of the neural network you can train. A larger memory will allow you to train larger models or use larger mini-batch sizes.

The computational power of the GPU, typically measured in floating-point operations per second (FLOPS), is another crucial consideration. A higher FLOPS value indicates a more powerful GPU.

Energy efficiency is also an essential factor, especially for those planning to run large-scale training jobs. More energy-efficient GPUs can lead to significant savings in electricity costs.

Finally, the price of the GPU should align with your budget without compromising the performance requirements of your deep learning tasks.

Other factors to take into consideration:

1. CUDA Cores: The number of CUDA cores directly influences the GPU's processing power. More CUDA cores usually translate to faster training times.
2. Memory (VRAM): Deep learning models with large datasets require ample memory for efficient training. Ensure that your GPU has sufficient VRAM to accommodate your model and data.
3. Memory Bandwidth: A high memory bandwidth facilitates the quick exchange of data between the GPU and the memory, which is crucial for speedy calculations.
4. Tensor Cores: Tensor cores, found in some GPUs, are specialised units for matrix operations commonly used in deep learning. They can significantly accelerate certain operations.
5. Compatibility: Ensure the GPU is compatible with your existing hardware and software stack. Also, check if it supports popular deep learning frameworks like TensorFlow and PyTorch.
