Understand the GPU and the Differences between CPU and GPU


The world of hosting is changing every day with the addition of some new features and specifications. A graphics processing unit is one of those features that are changing the configurations of the way we can architect dedicated servers. Over the years, GPU use has changed from its original role in rendering images and videos to gaming peripherals to essential components in scientific research, artificial intelligence, and data analytics. With such enhancements and their inclusion in these fields have changed the complete scenario. Let us here try to understand what are GPUs and the difference between CPU and GPU.

What Is GPUs?

GPUs, or Graphics Processing Units, are specialized electronic circuits designed to accelerate the processing of graphics and parallelizable computations. At their core, GPUs are specialized processors designed for handling complex calculations at remarkable speeds. In contrast to Central Processing Units (CPUs), which excel in sequential processing of a few intricate tasks, GPUs are masters of parallel processing. With hundreds or even thousands of cores, they efficiently manage numerous tasks simultaneously. Originally made for gaming, GPUs have become essential in diverse applications, evolving beyond desktops and servers to permeate mobile devices, enhancing capabilities while maintaining computational efficiency.

Importance of GPU in This Digital Age

In the digital era where data analysis by artificial intelligence is a choice of businesses, the significance of GPUs extends far beyond mere graphics, images, and video rendering. The power of GPUs in processing multiple tasks concurrently has made them most demanding in fields demanding high computational power. Since the need for such needs is increasing every day, its importance is increasing every day. Here is some importance of GPU in this digital age:

  • GPUs have played a crucial role in the development and advancement of technologies like artificial intelligence and machine learning. Many machine learning frameworks, such as TensorFlow and PyTorch, have GPU support, allowing researchers and practitioners to train and run deep learning models much faster compared to using CPUs alone.
  • Machine learning, data analysis, and complex simulations thrive on GPUs for their efficiency and speed, making them integral components in today’s computing era.
  • They are known for their primary role in rendering graphics for visual display. Today's complex game graphics, virtual reality (VR), and high-definition video content demand powerful GPUs to deliver smooth and realistic visuals.
  • Professionals in fields like architecture, engineering, and design rely on GPUs to run complex computer-aided design applications. These applications require substantial graphical processing power for rendering 3D models and simulations.
  • Certain cryptocurrencies, such as Bitcoin and Ethereal, rely on proof-of-work consensus mechanisms that involve solving complex mathematical problems. GPUs have been extensively used for cryptocurrency mining due to their parallel processing capabilities.




Difference between CPU and GPU

The fundamental distinction lies in the architecture. CPU vs GPU architecture divergence makes GPUs particularly adept at tasks requiring repetitive, parallel processing, such as image and video rendering, scientific computing, cryptocurrency mining, and deep learning applications. The difference between CPU and GPU is given below based on the top 5 factors:






General-purpose computing tasks, sequential processing.

Specialized in parallel processing, graphics rendering, and parallelizable computations.


Complex, optimized for diverse workloads.

Simple, with a large number of small cores optimized for parallel tasks.


Typically it has fewer cores and is optimized for single-threaded performance.

Hundreds or even thousands of smaller cores are optimized for parallel processing.

Task Execution

Executes a few tasks simultaneously but excels in sequential tasks.

Executes a large number of parallel tasks simultaneously.

Memory Hierarchy

Emphasizes high-speed cache for fast access to frequently used data.

Often has a less complex cache hierarchy, and relies on high-bandwidth memory for parallel data access.

It's important to note that CPU vs. GPU architecture have distinct characteristics, they are not mutually exclusive but often used together in modern computing systems to leverage their respective strengths for different types of workloads.

Dedicated servers with GPUs are designed to provide high-performance computing capabilities, especially for workloads that benefit from parallel processing, such as scientific simulations, machine learning, and rendering. The integration of GPUs into dedicated server structures enhances the server's ability to handle complex computations efficiently. Here's an overview of dedicated server structures with GPUs:

GPU Accelerators: Dedicated servers with GPUs include one or more GPU accelerators (Graphics Processing Units). GPUs are selected based on their parallel processing power and memory capacity. Popular choices include NVIDIA Tesla, AMD Instinct, and other server-grade GPUs designed for data center environments.

Memory: Dedicated servers with GPUs require ample system memory (RAM) to support both CPU and GPU processing. High-bandwidth memory (HBM) is often used in GPUs to ensure rapid data access for parallel computations.

Storage: Storage options include high-speed SSDs or NVMe drives to minimize data retrieval times. Storage configurations can be optimized based on the specific requirements of the applications running on the server.

Connectivity: Servers with GPUs often have high-speed network interfaces, such as 10 Gigabit Ethernet or faster, to facilitate data transfer between servers or with external storage systems.

Power Supply and Cooling: Due to the increased power demands of GPUs, dedicated servers with GPUs are equipped with robust power supplies and efficient cooling systems. Rack-mounted servers may include additional cooling mechanisms to maintain optimal temperatures in the power dedicated server.

GPU Virtualization: Some dedicated servers support GPU virtualization technologies, allowing multiple users or applications to share GPU resources efficiently.
