![]() ![]() ![]() A graphics card does run on 8x PCIe lanes, but performance is impacted, and a full 16x lanes are required to run at full speeds. The most important aspect of a processor for OctaneRender is the number of supported PCIe lanes, which directly affects the amount of graphics cards you can install. However, a processor with a fast clockspeed does help speed up loading times at the beginning of the rendering process. ![]() The render engine does not make use of a processor while rendering. Your CPU is not as crucial as your GPU in OctaneRender, but it is still important. Which CPU should I use for Otoy OctaneRender? RT cores are due to be supported in upcoming versions of OctaneRender, and early indications show they can improve render times by up to three times. They are specifically designed to accelerate ray tracing tasks such as those performed in OctaneRender. These graphics cards have dedicated technology built into them called RT cores or Ray Tracing cores. When selecting your GPU’s you should also purchase an NVIDIA RTX variant. If you require more graphical VRAM than NVIDIA GeForce cards can provide then NVIDIA Quadro is also a great option. With that said if you use any other applications that require NVIDIA Quadro, these cards work very well for OctaneRender as well. The highly popular class of graphics cards give fantastic results when rendering and has been a go-to choice for GPU render workstations for many years. We recommend NVIDIA GeForce for OctaneRender because they offer the most compute performance for your money. Upcoming releases of OctaneRender however, will introduce support for Vulkan API which may, in turn, bring support for AMD Radeon Graphics cards. Otoy OctaneRender has traditionally run on NVIDIA CUDA, and as a result, unfortunately, AMD graphics options are not compatible. NVIDIA GeForce vs NVIDIA Quadro Vs AMD Radeon Graphics for Otoy OctaneRender? Top-down cooling cards do not exhaust their heat directly out the case and therefore work well on their own, but do not cool adequately in multi-GPU configurations. These cards happily stack together in multi-GPU configurations and cool very effectively because the heat is directly exhausted out of the back of the chasis. We also recommend blower-style NVIDIA GeForce graphics cards such as those found on the the Workstation Specialists website for multi-GPU configurations instead of top-down cooling options. When configuring your system, tailor as much graphical performance as possible around your budget. Keep in mind that multiple mid-range cards often outperform a single high-end graphics card. It also scales near perfectly when adding additional cards, so we highly recommended multi-GPU options for OctaneRender. ![]() Therefore, high-end cards perform better and scale perfectly to the performance improvement each card up the range provides. OctaneRender is also exceptional at using up every bit of GPU performance available. GPU’s contain hundreds or thousands of cores whereas a CPU is limited to a few dozen at best. Otoy has made a solid choice here because rendering is a highly multi-threaded task meaning it performs better with more cores. OctaneRender is a GPU render engine, meaning that all the computing takes place on a GPU or graphics cards rather than a CPU. Let’s jump straight in with the most important aspect when building a system for Otoy OctaneRender, the GPU. Best Graphics Configuration for Otoy OctaneRender? Below we share all our findings to help you configure your next Otoy OctaneRender Workstation. We have worked extensively with Otoy OctaneRender users to provide tailored, purpose-built Workstation solutions for this exceptional render engine. Slow render times leads to missed deadlines, reduction in your production capacity and ultimately can cost you time and money. The demands of an unbiased render engine mean you need the right Workstation solution to get quick results and work efficiently. OctaneRender fully calculates each ray of light, delivering highly accurate depictions of your scene. Unbiased render engines do not use any tricks or cut any corners to speed up renders. With the high resolutions often required in OctaneRender projects and the unbiased nature of the render engine, it is especially true for this software package. Rendering any scene is a demanding task for Workstation hardware. With the performance capabilities OctaneRender provides, and the extensive list of applications it plugs into, it is easy to see why it is so popular amongst professionals. Otoy OctaneRender is one of the worlds most popular and fastest unbiased render engines in the world.
