The graphic above summarizes the median 512x512 render speed (batch size 1) for various GPUs. Filtering is for single-GPU systems only, and for GPUs with more than 5 benchmarks only. Data is taken from this database (thank you vladmandic!). Graph is color-coded by manufacturer:

• NVIDIA consumer (lime green)
• NVIDIA workstation (dark green)
• AMD (red)
• Intel (blue), seems there's not enough data yet

This is an update/prettier visualization from my previous post using today's data.
