I found some of the design choices in the xbone quite strange, however i am impressed with how they have structured the memory to help compensate for the DDR3 bottleneck. So the 32mb ram will do read and write processes at high speeds. Its just getting the data over to it. DDR3 is not slow, it just cant read+write in a single cycle. Will be interesting to see how this memory can handle multiple variables, or more to the point, how developers are going to handle the different memory pools.

Nintendo should take notes. M$ has improved on their design in every way possible by the looks of this.

Without a doubt, MS evaluated unified GDDR for the xbox one as they pioneered it in the 360, but there's adequate bandwidth and there's overkill. Especially when half of the RAM is going to be allocated to OS functions.
