With the release of Turing NVIDIA created a new class of GPU devices specifically tailored to target ray tracing workloads. Unfortunately, Blender Cycles does not support HW accelerated rendering just yet, nevertheless, the new RTX GPUs provide a significant leap in GPU performance. In this article we compare the performance speedup with Blender v2.79b and Blender v2.80 beta using three top-end GPUs - RTX 2080 Ti, Titan V and GTX 1080 Ti - Turing, Volta and Pascal. Additionally, varying tile size measurements give further insight to extract maximum speed from Cycles.
