CPU vs GPU for Machine Learning

Most people believe that the CPU is the most critical component of a computer – it is referred to as the computer's brain. However, the GPU may be a more suitable option for machine learning tasks.   

GPUs are designed for parallel processing, which makes them better suited for matrix operations required by machine learning algorithms. In this post, we will compare the performance of CPUs and GPUs when performing machine learning tasks. We will also discuss some factors to consider when choosing a processor for machine learning.   

CPU Vs. GPU: The Basic Difference   

A Central Processing Unit (CPU) is the traditional processor in most PCs and laptops. On the other hand, a Graphics Processing Unit (GPU) is a processor designed to manipulate computer graphics. A CPU processes a computer's fundamental instructions, such as arithmetic, logic, and I/O operations. GPUs are usually present in computers built for gaming or other graphics-intensive applications.   

Should one opt for a GPU for machine learning instead of a CPU? The answer is 'Yes.'   

It is because GPUs are faster and more powerful than CPUs regarding specific calculations. These calculations are needed to train complex machine-learning models. Moreover, the speed of a GPU can be critical when working with large datasets or training complex models.   

How Do GPUs Work?   

GPUs are designed to render images and videos quickly. Businesses can also use them for other types of calculations needed for machine learning. A GPU consists of thousands of cores that can work together to perform parallel computations. It makes them well-suited for machine learning tasks, which often require multiple computations to be performed at the same time.   

Cloud GPUs are also faster than CPUs regarding memory bandwidth – the amount of data the device can transfer between the processor and memory per second. It is vital for machine learning because it allows the model to access data quickly, speeding up training time.   

For example, a midrange CPU will cost around $500, but you'll need to spend a little bit more on a comparable GPU. However, remember that a powerful GPU is required to train complex models or work with large datasets. Hence, it justifies a tiny gap (increase) in the price. Also, training deep neural networks can require expensive GPUs with thousands of cores, but moving to cloud GPU can fit into the budget.    

Conclusion   

While considering a CPU or GPU for deep learning, companies must consider several things, including cost, speed, and power. We recommend using a Cloud GPU for machine learning tasks whenever possible. They're generally faster and more affordable than CPUs or traditional GPUs while offering enough control for most applications.
