2.77 for the press demo and 100 samples that ran 25 seconds, 2.78a for New Horizon 150 samples 36 seconds
OK, thanks - that was bloody confusing

Cinebench is NUMA aware. Blender isn't. Scaling is nearly linear for low core counts. For much higher core counts, it drops ofd fast.Scaling is something like 99% with CB 11.5, dunno for Blender but it seems to be in the 95%+ range..
One of AMD's employees chimed in and confirmed they were using the Haswell-E cooler, forget the part number. Don't think it mattered much though since the runs were pretty short.I saw something interesting on reddit the other day. Someone pointed out that AMD said that these CPUs were using stock coolers.
The stock intel cooler, which correct me if I am wrong, doesn't even come with the 6900k. But could they have used that tiny cooler anyway? Could this explain some discrepancies that people are seeing?!

There is an AIO intel water cooler.HMM? I have a 5960x which is Haswell E and it did not come with a cooler.
Perhaps he meant a cooler designed to handle Haswell E heat output?
Intel did market an upscale heatsink but most Haswell E users bought a separate non intel cooler or like me, water cooled.
That odd that both are the same - and they are lower than my rig (4.0 GHz core, don't remember Uncore and QPI).
I don't know dude, here is the post: https://www.reddit.com/r/Amd/comments/5ihole/amd_convinced_me_to_wait_for_zen/db8izzw/HMM? I have a 5960x which is Haswell E and it did not come with a cooler.

Just for giggles... on my quad Opteron system i set 16 of the K10 cores to 3.4 GHz (to match Ryzen), set threads in Blender to 16, and set thread affinity for Blender to them and reran (150 samples). Result: 46.99 seconds.
Basically AMD must have been lying their rear ends off as far as throughput (40% my rear). Each Zen core is indeed pushing between 2.5 and 2.7 K10 cores worth on blender... and one Piledriver core at same clock is only worth around .85 of a K10 core (at least on Cinebench).
AMD might as well name the thing Phenom x20+ because that is what this thing is the equivalent of (conservatively speaking).
Kudos to AMD for creating the biggest sandbag job in x86 CPU history )))))
I doubt this will be case for other applications. these Blender versions clearly run like shit on Excavator, and seemingly K10 also , not really representative, unless one believes Broadwell also is 2.7x a K10 core
