![]() GPUs come with different amounts of video memory (VRAM) such as 8GB, 11GB, 12GB, 16GB, 24GB, or 48GB. Please refer to this guide on enabling it. This feature was introduced in a 2020 Windows 10 update along with compatible NVIDIA drivers. In other words, CPU-GPU communication is faster by default on Linux than Windows (with WDDM) across all NVIDIA GPUs including GeForce and Quadro/Tesla/Titan GPUs.Īlthough GeForce GPUs lack TCC support, you can still get some of its latency benefits on Windows by enabling “Hardware-accelerated GPU scheduling”. ![]() TCC is only useful for Windows – Linux does not need it as the Linux display driver does not have the communication latency issues of WDDM on Windows. Only Quadro, Tesla, and Titan GPUs support TCC. The downside of TCC is that once enabled, the GPU becomes “invisible” to Windows and 3D apps like Maya, Houdini, etc and only works with CUDA apps like Redshift. TCC stands for “Tesla Compute Cluster” – a special Nvidia driver for Windows that bypasses the Windows Display Driver Model (WDDM) and allows faster communication between the GPU and CPU. Redshift allows the mixing of GeForce and Quadro GPUs on one computer.Īn important difference between GeForce GPUs and Titan/Quadro/Tesla GPUs is the TCC driver availability. Quadros’ main benefit over GeForce is that they often have more onboard video memory (VRAM), which could be important for rendering very large scenes. The Quadros can typically render OpenGL viewports faster than the GeForce, but it does not affect Redshift’s rendering performance. Please note that there are almost no performance differences between GeForce and Quadro GPUs for Redshift rendering. ![]() Among the professional GPUs, it’s the last-gen Quadro RTX 5000 and Quadro RTX 6000, or the current-gen Quadro RTX A6000. From NVIDIA GPUs, it’s recommended the last-gen GeForce RTX 3060 Ti, RTX 3070, RTX 3080, RTX 3090, and the current-gen GeForce RTX 4090. ![]()
