For a given BER and a given noise power, GMSK will require more signal power as compared to BPSK. However, the GMSK signal, when viewed in the frequency domain, will have a narrower bandwidth than the BPSK signal.
In case anyone is interested in the mathematical derivation of the Pe (probability of error) for BPSK and GMSK, see "Modern Digital and Analog Communication Systems: 4th Edition", B. P. Lathi and Z. Ding, pp. 516-525.
Simulating and graphing these systems in MATLAB or, my preference, Octave, is enlightening. One can plot the theoretical Pe versus Eb/N0 for both systems and then do a Monte-Carlo simulation (die rolls) to plot something more real-world.
A good book to show how to write simulations is "Contemporary Communication Systems Using MATLAB" by Proakis, who also has one of the definitive texts on communication systems.
I've used both books for several communication system courses.
