![]() ![]() The firm says that it plans to iterate on performance in future updates, but that it does not expect Redshift CPU to challenge Redshift GPU for raw speed. ![]() However, Maxon describes it as “the first steps to a full CPU version” with “a lot of room for improvement with performance”: in particular, hybrid renders may currently actually be slower than rendering on GPU alone. The initial release supports all of the features of Redshift GPU, with the exception of Round Corners, and CPU and GPU output should be “perceptually indistinguishable”. Rendering on the CPU also avoids two disadvantages of GPU rendering: the performance hit associated with rendering scenes too large to fit into GPU memory, and the high current street prices of GPUs. On the Redshift forum, Maxon notes that CPU support “opens up doors for Redshift to work on CPU render farms”, including commercial rendering services, and the CPU farms maintained by many large VFX facilities. It’s a striking addition to a product whose tagline is “the world’s first fully GPU-accelerated, biased renderer”. The main new features in Redshift 3.5 are Redshift CPU and Redshift XPU: new modes for rendering fully on the CPU, or on both CPU and GPU simultaneously. Redshift CPU and XPU enable users to render on CPU as well as GPU The firm has also announced support for AMD GPUs on Windows and Linux, due in beta in a future release. Other key changes include a new Redshift Standard Material, intended to improve interoperability with other DCC applications and better rendering of thin-film iridescence and diffuse roughness. The update enables the formerly GPU-only renderer to run on the CPU. The video also shows some features added in other recent updates. Both AMD Software and Redshift support for AMD Radeon Pro graphics cards on Windows are currently in a closed technology preview and development is actively ongoing.Maxon’s release trailer for Redshift 3.5, the latest version of its production renderer for 3ds Max, Blender, Cinema 4D, Houdini and Maya. ![]() Redshift is also validated on the AMD Radeon Pro VII graphics card. To run Redshift on the supported AMD Radeon Pro W6800 graphics card will require the AMD Software: Pro Edition 22.Q1 driver available later this quarter. “This development brings us even closer to that achievement and also satisfies one of the community’s most desired feature requests.” “Our ultimate goal is Redshift Everywhere, in the hands of every artist on every DCC application, with the ability to take advantage of all the capabilities of their hardware,” said David McGavran, CEO of Maxon. Redshift also supports rendering with mixed devices like RS CPU and AMD Radeon Pro graphics cards, so firms can work with a variety of hardware setups – whether it is Nvidia on one machine, AMD on another, or CPU only. ![]() According to Maxon, this means developers can write their GPU applications and, with very minimal changes, run their code in any environment with comparable performance across platforms. HIP is a C++ runtime API and programming language designed to support easy migration from existing CUDA code. The AMD dedicated GPU programming environment – Heterogeneous Interface for Portability (HIP) – is designed for programming high performance kernels on GPU hardware. The production-class render engine now offers photorealistic rendering via AMD (HIP), Apple (Metal) and Nvidia (CUDA) technologies, while anyone can work with Redshift materials and rendering through Redshift CPU. Redshift, the GPU-accelerated biased renderer from Maxon that works with Cinema 4D, Maya, 3ds max, Blender, Vectorworks, Archicad and others, can now be accelerated by AMD Radeon Pro GPUs.
