I'd guess that the LLVM backend could generate code that is at least as fast as gcc. It would be nice if you could test it.
NCG done with GHC 6.12.1 w/ -O3 LLVM using a version of HEAD w/ -O3 GCC version 4.4.3 w/ -O3 Please take note Johns benchmark of JHC showing it beats everything here (including C). Also note -Odph did not alter performance from -O3.
