I found that 603e/G2_LE/"e300c0" does only 0.4 MFLOPS per MHz according to a posting on powerdeveloper.org:
I don't know if that's single or double precision (or even both) but either way if both my interpretation of that figure and my assumptions above are correct, then it doesn't bode too well for the floating point performance of the e5500 in general as well as compared to the Titan (or probably rather its replacement) specifically.
