Sign up ×  I don't have the cash to stump up for a PS3 or 360
devkit, but the G3, G4 and G5 macs are running with PowerPC
chips, which I believe is virtually the same architecture as the
360, and only missing the SPUs from the PS3, so I would like to
know which Macs would be good for profiling code with.  I'm
after a machine that would give me equivalent timings (not
actual timings, but scale the same given difference code) so I'm
looking for ones that have about the same cache size and memory
bandwidth ratios as the consoles. Are there any specific Macs
that have these traits?  The reason I need one is that I'm
developing a new programming language for games development that
specifically targets the current and potential future of console
hardware. One aspect of this is the in-order microcode expanding
risc chips at the core of both the 360 and the PS3, and probably
the next generation too, which is why I want a PPC based mac, as
I'd heard that places like where I work used to use Macs as
pretend 360 devkits
