This is like a hard comparison; you can't really compare the two.
Howver, both have an ADC. GPS receivers usually have correlator banks to detect the signal, yielding a large processing gain by effectively using half eternity of energy.

Well, presumably projects like http://gnss-sdr.org/project   are using one or more correlators, but in software, rather than hardware.
