Mark van Dijk wrote a new Cycles benchmarker that can automatically upload test results to his website to compare them to others.
A few weeks ago I saw some screenshots from old Blender versions. I noticed a button called "benchmark", but when i searched for it in my own copy of blender (v2.70a) I couldn't find it. I went searching for a benchmark addon, but couldn't find it either. I was looking for a project to learn python, so why not make that addon myself? I started right away, things went smoothly and after some testing I decided last weekend to go public.I call the addon BlenchMark.It's a benchmark for Blender, and my name is Mark (that's why the M is capitalized). It let's you run a benchmark, see your results and upload them to the webiste I made for it. On the website you can see how you did in comparison with other renderdevices. If you run this benchmark in every new Blender version it becomes visible if Cycles is getting faster or not. There are some other useful statistics too.
The website is running at a subdomain of mine. When this addon really gets used by a number of blender users, I will move the website to its own domain. The addon is available for download at the website.
I'd like to thank the Dutch Blender community members for helping me with their testing of this addon. It really helped me getting this done.
I hope to see your benchmarks soon!
