The entire conglomerate is on another level and approx. double the size of Samsung Electronics.
"I cannot find what proportion of Apple's profits come from sales of iPhone and iPads; they do [...] make up a majority of their revenue."
it's imo very safe to assume that.
They sold an astonishing 26.9 million iPhones in Q3, 58 percent growth compared 2011. Also 14.0 million iPads (Q3), 26 percent growth.
With a 4.9 million Macs sold (only 1 percent unit increase) and a 19 percent decline with Ipods, i guess it's safe to assume that most of their revenue (especially additional revenue compared to last Q3 earnings) comes from Iphones/Ipads.
All numbers from official press release:

Anyway: Good job Samsung :)

Looks like 90% ish. Really astounding to see Apple and MS profits side by side like that. From ~10% of MS to nearly double over less than five years.
Approximately $5.1B of Samsung's profits came from their phones; this is despite Samsung being an extremely diversified company. I cannot find what proportion of Apple's profits come from sales of iPhone and iPads; they do, however, make up a majority of their revenue.
