Top 7 Best GPU Render Engines – Our Top Single-GPU & Multi-GPU Rendering

When GPU rendering was born, we saw a marked change in the rendering speed of GPU rendering compared to CPU rendering: faster than CPU rendering. Nowadays, GPU Rendering is considered not only a trend but also an essential rendering type for most 3D artists globally. And GPU render engines come with it.

In front of many GPU render engines, which is the best choice for you? And what are the best GPU render engines? In this article, VFXRendering will be going to list the 7 best GPU rendering engines including single-GPU & multi-GPU rendering engines. Before we proceed with the ranking, we will go over some essential concepts about render engines.

Best GPU render engines

What is GPU renderer?

GPU render engines or GPU-accelerated renderers, it is an engineered program based on such disciplines as light physics, mathematics, and visual perception. GPU rendering engines use GPU card-based for rendering. Some rendering engines use single-GPU for rendering and some others use multi-GPU (over 2) for rendering. It is called a single-GPU render engine and a multi-GPU render engine.

Some popular names of GPU renderers include Arnold GPU (Autodesk), Iray (NVIDIA), Octane (Otoy), Redshift (Maxon), FStorm, V-Ray RT (Chaos Group), Lumion, Enscape, Twinmotion, etc.

What is the best GPU Render Engines?

We will classify them into 2 groups: single-GPU rendering engines & multi-GPU rendering engines. We only list alphabetically, not in ranking. Let’s get checked!
