Rather interesting... i went through the submissions on the Ryzen 150 thread and converted them as well.
i only found one submission with a higher value... a Skylake 6700K sample. Its too bad that how good AMD's SMT implementation is not known... but typically (R15 score / 1.25 / # cores) gets in the ball park (with the newer Intel chips).

Looks like Ryzen sits right in between Haswell refresh and 6700K. 1519 would be the 8 core Haswell refresh score at 3.4 GHz, and 1562.3 would be the 8 core Skylake score. Split the difference... you end up with a projected Ryzen score of 1540 (actually slightly below that since not exactly half). Do the usual formula (1.25 for SMT when running Cinebench), and you end up with 154 for single thread at 3.4 GHz and 176.6 if they can turbo single core up to 3.9 GHz.
So basically we are looking at Ryzen CB R15 of 1540, and 154 ST assuming 1.25 SMT.
Interesting that Athlon X4 845 still has not caught up with K10 all these years (almost equal) in Blender. In CB R15 its just very slightly ahead in ST.
Here's my Ryzen.blend results:

FreeBSD 11.0
Blender 2.76, 150 samples (total samples = 800*800*150)
Code:
1 core: 7 minutes 42.86 seconds 69135 samples/s/core/GHz
2 cores: 3 minutes 52.16 seconds 68918 samples/s/core/GHz
4 cores: 1 minute 57.42 seconds 68131 samples/s/core/GHz
8 cores: 59.99 seconds 66678 samples/s/core/GHz
16 cores: 31.40 seconds 63694 samples/s/core/GHz
1 core, 2 threads: 6 minutes 14.92 seconds 85352 samples/s/core/GHz
16 core, 32 threads: 26.31 seconds 76017 samples/s/core/GHz
I took the liberty of adding samples/s since that makes quantification easier. Looks like our systems have about 10% decrease in IPC from low cores to max cores.
