Yes, Apple’s R&D expenses rose to $1.9 billion. For comparison, Microsoft spent $2.9 billion on R&D over the same period.
And while Apple spent 3.3% of its revenue on research, Microsoft spent 14% of its quarterly revenue.
Apple had revenue of $58 billion. MS had $21 billion.
So, Apple spends only 65% what Microsoft does on R&D while making 2.8 times more.
Apple is thus over 4 times more efficient with every dollar it spends on R&D.
