I'd like to have some examples. Games on PS3 also used SIMD a lot (at least relatively speaking), but that was because GPU was bad (compared to current ones), so much of the now-obviously-on-GPU code was run on CPU. Using SIMD for something that today makes more sense to run on GPU isn't really relevant anymore.
