NVIDIA GeForce RTX 3080 Founders Edition Review- a big step forward and the tombstone for Turing

Rendering

Now it’s getting really interesting, because Arnold is the latest raytracing renderer from Autodesk, designed to meet the needs of feature-length animation and visual effects. Arnold is used in over 300 studios worldwide, including ILM, Framestore, MPC, The Mill and Digic Pictures and others. Arnold was also the primary renderer on dozens of movies, from Monster House and Cloudy with a Chance of Meatballs to Pacific Rim and Gravity. It is available as a stand-alone renderer for Linux, Windows and Mac OS X and as a plug-in for Maya, 3ds Max , Houdini, Cinema 4D and Katana.

NVIDIA and Autodesk have worked together to accelerate raytracing in Arnold using RTX GPUs. This allows artists to work more interactively with their models and spend less time waiting for their hardware. The combination of fast RTX-accelerated rendering and GPU-accelerated AI denoising also allows for rapid iteration through changes in materials, lighting, camera position and environment, with effects visible with lightning-fast updates.

You can see the advantage of the RTX cards compared to the older Pascal models very clearly, because the slowest Turing RTX is still almost twice as fast as the older Pascal flagship. And the new GeForce RTX 3080? it wipes the floor with everything else, even the Quadro flagship RTX 600. That’s what you have to do first, chapeau.

Blender is an extremely popular free and above all open source 3D suite. It supports almost the entire range of 3D pipeline modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing, and 2D animation. In other words, almost everything that the topic offers. Since the release of update 2.81, Blender now supports RTX-accelerated rendering using the NVIDIA OptiX rendering API in the Cycles renderer.

This shortens render times on NVIDIA RTX GPUs and speeds up rendering compared to CUDA or OpenCL. Measuring the final render times is a good way to evaluate the capabilities of GPUs when it comes to working efficiently and as unobstructed as possible. The GeForce RTX 3080 FE crushes everything around it to finest pixel dust, just like in Maya and Arnold. Twice as fast as an RTX 2080 Super, which scales almost 100%.

Besides OptiX, Blender can also use only GPU acceleration (CUDA or OpenCL) to render directly on the GPU with Cycles. And this is exactly where it becomes interesting to compare both approaches including the appropriate maps with my igoBOT, which is much more complex than the other two models.

The GPU renderer on the older 3ds is also a domain of the GeForce RTX 3080 FE, although here of course the geometric mean distorts the distances somewhat. The distance in front of the RTX 2080 Ti is however larger, than its projection to the RTX 2080 Super.
