We kinda had that world with the PS3 and SPE/SPUs[1]. Stuff written for them tended to run faster on more traditional hardware since you needed to vectorize all of your loads(which made the prefetcher on other hardware really happy) but it was an absolute beast to port in any code. I remember stuff from PC/X360 just running like absolute garbage(not that multicore was well handled anyway during that era) until significant refactoring was done(up to and even including full rewrites in some cases).
