what diff Jasper with Valhalla?
>Xenos- this is the first version. The launch versions of xbox 360 core and pro came with this motherboard. This has no hdmi port. Failure rate around 33%.
>zephyr- this is also a first version. The launch models of xbox 360 elite came with this one. This included the hdmi port. But microsoft later put this motherboard with all xbox 360 models so all had hdmi port. Failure rate around 33%.
>falcon- this is the first revision that came around september 07. This reduced the cpu to 65nm from 90nm. The power supply was reduced to 175w. This revision also reduced the failure rate to around 16%.
>jasper- this is the second revision that came around september 08. This also reduced the gpu to 65nm from 90nm. So both the cpu and gpu were 65nm. The power supply was reduced to 150w. This reduced the failure rate to about 7%. Although as this had been out for only about a few months, so we can't tell about its actual failure rate.
>valhalla- this is supposed to be the third revision that is supposed to come around the end of this year. This one will combine the cpu and gpu into a single chip and reduce the size to 45nm. The power supply will be reduced to 100w. This one will be cooler and is supposed to reduce the failure rate even lower than jasper.
