I know Hyper Pi is multithred and Super Pi is single thread. Since the Broadwell-E has Turbo 3 and picks the best core to run at higher than normal turbo speeds, shouldn't the times be the same in 32m between both? Core 5 (I have no clue why Intel starts with 0) is my best core. Hyper PI 32m took 11:30 on core 5. Super PI only took 8:48. Why such the big difference?

Actually 99% of everything in computer world is going to be 0 indexed. Reason being 0 is the first non negative number, and is represented in binary as all 0s and no 1s. If you study any programming language you will get familiar with 0 indexing very quickly.

HyperPi uses all cores, shares cache, shares memory etc. It's normal that more cores = worse time, it's always like that. Set 1 core in HyperPi and you will see it will pass faster than 6 at the same time.
