Thank you. Interesting.

My 4th gen i3 at 22nm relative results a lot like your earlier 32nm 
generation i3 results. My i3 the same generation as your i5, but the 
relative differences are larger. Oh! your i5-4570 looks to be limited to 
one thread per core, so yeah, that looks not too different than my 2 
core results.

Looks to me, more or less, lines up performance difference with what I 
see too - the SDL coded version is faster... Didn't say it outright, but 
my guess is in the SDL method the pow()s are tossed at the processor 
somewhat slower and so 'fewer/(none?)' are asked to wait for some set 
time period.
