Though it might take hours (maybe even days) to finish rendering an image, traditional CPU-based rendering is more likely to deliver higher image quality and much clearer images that are devoid of noise.Ī GPU has many more cores than a CPU, but overall, each core runs slower compared to a CPU core. Rendering is a time-consuming process, but quality can’t be rushed. If speed is the main priority in your workflow, GPU-based rendering is the preferred solution. Hours of processing can be displayed in minutes and can streamline the design process when using GPUs. Where CPUs generally are able to handle individual specific tasks in sequence, GPUs offer superior memory bandwidth, processing power, and speeds up to 100 times faster to tackle several tasks that require multiple parallel computations and large caches of data. Modern GPUs have increased in their output capabilities since they were first introduced. While a CPU has a limited number of processing cores (averaging at around 24) that make it efficient at sequential serial computing and carrying out processes one at a time, GPUs consist of smaller cores in greater quantity than that of an average CPU, allowing your workstation to perform multiple tasks at the same time much more quickly. The first and most obvious factor to address is speed.

Making the Choice Between CPU and GPU Rendering.

Hopefully after reading this, you will have a better, more comprehensive understanding of what these types of rendering solutions can offer you and your studio and assist you in making a more educated decision as to what is a better option for your projects. These processor-intensive tasks may include:įor the sake of not overcomplicating this article or its purpose, we’ll be exclusively referring to comparing CPUs and GPUs used for image processing, or in this case, image rendering.

Graphics Processing Units (GPUs), which are specialized types of microprocessors that run parallel to the CPU, have recently seen a significant rise in usage as massive calculations that are needed for a single task begin to grow.

The Central Processing Unit (CPU) is the heart of your workstation and handles a lot of tasks, like executing applications, loading drivers, etc. When working in one of these industries, the most important tool in your arsenal is your workstation. High-definition image processing is the life-blood of today’s VFX, graphic design, industrial design, and animation industries.
