PC Perspective has a nice, well photographed, dissection of the new Xbox 360 hardware for those who like those kind of things. Turns out that the change in architecture is more significant then I thought particularly since the CPU and GPU are located beneath the same hood. The relevant information is on page 3 of the article and it some fascinating stuff that hardware geeks will dig. PC Perspective sums it up nicely:
Either way, the change from a technological perspective is important and noteworthy as it is the first instance of a “high performance” graphics core being paired with a “high performance” CPU core in a product that will see millions of sales. Yes we have the Intel Core i5 processors but I wouldn’t put the Intel HD Graphics core on par with the Xenos-based design here. And while AMD’s Fusion parts will fall into this same realm we are still months from seeing production parts.
I don’t know if this means anything to average console gamer or not but for those of us still somewhat entrenched in the PC Gaming side of things it is a fairly significant achievement. If I’m reading this right and AMD’s Fusion does manage to take off it is entirely possible that gaming on an integrated graphic processor might actually be feasible. Of course the upgrade path for such a system is still problematic (i.e. the same problem that consoles have) but still a fascinating development if applied to the HTPC market.
