The fast cloud rendering services provider and GPU&CPU render farm, Super Renders farm will share with you 4 rendering engines used for multi GPU rendering.

It is well known that GPU rendering can be performed using a graphics card instead of a CPU to render and can be significantly faster, as GPUs are primarily tailored for fast image rendering. GPU was created to cope with graphics-intensive applications that can burden the CPU and hinder computational performance. The principle of GPU rendering is to run across multiple cores on multiple data, putting parallel processing focused on one specific task, while freeing up the CPU to emphasize different sequential serial processing jobs.

With the reduction in GPU rendering times, there is a wide variety of rendering engines that utilize GPU rendering. In particular, simultaneous rendering using multiple GPUs can be 5 or 10 times faster than a single GPU. As a result, some of the world’s leading brands are focusing primarily on developing products that optimize multi-GPU performance. Maxon and Otoy, which bring great rendering solutions, reduce the rendering time burden for 3D artists, designers, filmmakers, etc.

The multi GPU rendering engines widely used today are Redshift, Octane, Vray, Iray, Fstorm, Eevee, Cycles, which have matured significantly and are outpacing CPU-based rendering engines in terms of both popularity and rendering speed.

Top 4 Multi-GPU Rendering Engines

1. Redshift

Redshift Rendering Technologies Inc was founded in California in early 2012 with the goal of developing production-quality, GPU-accelerated renderers that support biased global lighting technologies that have hitherto been entirely within the CPU domain. Redshift is now part of the Maxon family and is rapidly becoming the first choice of rendering engine for the motion design community. The Redshift rendering engine supports a selection of 3D programs: Autodesk Maya, Autodesk 3Ds Max, Maxon Cinema 4D, Houdini and Katana.

Recommended hardware requirements:

  • RAM: 16GB RAM or more
  • CPU: Core i7 or Xeon equivalent, 3.0GHz or higher
  • Graphics card: with 7.0 or higher CUDA computing power and NVIDIA GPU with 10GB or higher video memory: NVIDIA Quadro, Titan or GeForce RTX GPU for hardware-accelerated ray tracing.
  • Multiple GPUs

2. OctaneRender

OctaneRender® is one of the world’s first and fastest bias-free, spectrally correct GPU rendering engines, offering quality and speed unmatched by any production renderer on the market. As a product of Refractive Software, Octane was founded by Terrence Vergauwen, the lead developer of LuxRender, and in March 2012, Refractive Software was acquired by Otoy, who also received investment from Autodesk. Now as part of the Otoy family, Octane supports 3Ds Max, Maya, Cinema 4D, Houdini, Daz Studio, Unreal Engine and many other softwares.

Recommended hardware requirements:

  • RAM: 16GB RAM or more
  • Graphics: with CUDA computing power 3.0 or higher; and 10GB video memory of NVIDIA GPU: NVIDIA GeForce RTX GPU, GTX, Quadro, Titan
  • Multiple GPUs

3. EEVEE VS CYCLES

Eevee vs Cycles are the two main GPU rendering engines for Blender, the Blender Foundation’s open source 3D creation software that enables users to handle all aspects of 3D work. It includes modeling, animation, game creation, visual effects and much more. Blender is easy to download, customize and work on your own terms. The software also offers a large number of plugins for creating various types of models, animations, sculptures and more. Ultimately, comparing Evee with Cycles is more or less just comparing real time with ray tracing.

Recommended hardware requirements:

  • RAM: 16GB RAM or more
  • CPU: 64-bit quad-core CPU
  • Graphics card: At least 4GB of video memory
  • Multiple GPUs

Optimal hardware requirements:

  • RAM: 32GB RAM or more
  • CPU: 64-bit octa-core CPU
  • Graphics: 12GB VRAM or more, RTX GPU, Quadro
  • Multiple GPUs

4. FStormRender

FStormRender is a new GPU-driven, unbiased renderer with good performance that is quite easy to use. It uses convenient materials and light sources, it is simple, fast and realistic. Currently, FStorm GPU rendering engine is only available for 3Ds Max software. We hope that this amazing renderer will be available for major 3D software in the near future.

The FStormRender has many unique features such as improved tone mapping, glossy reflection shaders, glare effects, light sampling, improved ray tracer and optimized QMC sampling. The FStormRender is deeply integrated into the 3Ds Max environment and supports all necessary and critical features. The built-in scene converter allows easy and careful conversion of any scene from Corona, Octane and Vray renders. Fstorm is interactive, allowing the user to change the scene as it is rendered and to view these changes interactively without reloading. Any scene changes (other than geometry) are automatically reflected. Geometry changes require enabling live geometry updates or pressing the Reload Geometry button. Users can move the camera and get live updates in the frame buffer window.

Recommended hardware requirements:

  • RAM: 16GB RAM or more
  • Graphics: NVIDIA Geforce GPU: RTX and GTX series
  • Multiple GPUs
