After a quick look, it's much different.
bochs aims to completely emulate an x86 machine, including the
various HW devices, and in a portable way. I aims to run a whole
operating system (linux,windows,ms-dos, ...) within the emulator.
qemu is a dynamic recomiling emulator (thus less portable, though
potentially much faster) and doesn't do any HW emulation outside
of the CPU itself.
It translates syscalls to the kernel in order to run linux x86
userland binaries on linux ppc.
