[quote name='hypertails02']Jasper is basically a processor chip that makes the Xbox 360 run more efficiently. This, combined with a much improved heatsink, will prevent the console from getting the Red Ring of Death from overheating.[/QUOTE]
I think Jasper just refers to the internal naming of the currently newest revision of the xbox 360 hardware-I am not sure that they have use a different processor chip (I think they may have used the newer 65nm CPU in the previous revision-Zephyr or something) I think Jasper has a newer GPU, and from what I can remember, the GPU is the main culprit behind the RRoD rather than CPU
just my 2 cents
