The Wii U and Xbox 360 were also triple core machines... both triple core powerpc processors with ATI graphics... Was IBM having a sale on 3 core ppc hardware that year?
I never thought about it before but I actually had to look up die shots to make sure they were not the same processor. and if I can trust the internet they are not. Hell I had to confirm that yes the playstation 3(also ppc, queue x-files theme) only had the one core and it's screwball subprocessers like I remembered.
- swiftcoder 1y agoInterestingly, the single PPE core in the PS3 and the 3 cores in the Xbox 360, are pretty much the same core.
- Narishma 1y agoI think the SIMD is different between them. I don't remember the details but it was beefed up on the Xbox 360 because it didn't have the SPEs like the PS3.
- numpad0 1y agoThe world was way richer back then and could afford to spend time and money building desktop scale CPUs for game consoles that sells just tens of millions over few years. They just constantly made new CPUs. To me, the executive level idea was to spare a core for system and minor peripheral tasks - almost all game console before that generation had single CPU architectures with no resident operating system. Transitioning away from a manually coordinated, single threaded code, to an asynchronous multithreaded programming model, was a challenge in itself, and having to deal with it while operating system forced by the console manufacturer taking away control might have been too much for developers. (Sega Saturn had 2x SH-2, Dreamcast was to have WinCE on ROM but cancelled. Sega being Sega)
