Espresso is actually not as weak as some people think it is and I never once thought it was. The 15GFlop estimate is based on estimation that's on outdated documentations as well. They already modified the 750 once to get better FP performance on the Gekko and nobody knows what they did with the Broadway or the Espresso afterwards. The only thing we still know is that the Wii U is incredibly efficient while not matching up in power to the X1 or PS4 is about it. We need more data than all this guess work bullshit.

I wonder if your going to doubt this hackers work. 

You know what this means, right ? 15 gflops is actaully really close to the estimate of the theoretical performance. 

I know his work quiet well since I'm also in the mod scene, but he's not the God of computing so he can't see all the SIMDs in there from voodoo magic without documentation, and until somebody writes legit benchmarking tools that can actually push the hardware, we won't have hard numbers, and that's what I want to see instead of all the guesswork that's been going on for about a year now.

He pretty much said that those cores are exactly the same from broadwell aside from clocks and cache so it's safe to assume that it has a 64 bit FPU much like the broadway. What's more is that the ibm espresso can't deviate too much from it's archiecture otherwise it won't do backwards compatibility. BTW IBM has better things to do than to improve on the crappy architecture of the gekko/PowerPC 7xx series cores such getting that new POWER8 processor out there.
