And that is on all sixteen cores. As it seems a user on redddit called "callingthewolf" is showing off an AMD Ryzen Threadripper 1950X  tweaked towards 4.1 GHz. 

The proc normally has a base frequency of 3.4 GHz. He gets his Threadripper towards 4.0 GHz @ 1.25 V core already, yet needs 1.4 V on the core to reach 4.1 GHz. While spotted via wcctech, Callingthewolf used a Thermaltake Water 3.0 liquid cooler and an ASRock motherboard with all DIMM channels in use, that would be 8 x 8 GB running at 3066 MHz DIMMs. The scores then, a 4.0 GHz  Threadripper 1950X reaches a nice 3337 points in Cinebench R15. At 4.1GHz 58391 points in Geekbench 3. Not bad for a "glued together" product.

The results are indicative that Threadripper will perform and tweak similar towards Ryzen. Yet now with 12 and 16 cores.
