More Rumoured ‘Xbox 720’ Next-Gen Specs Surface


It’s been less than a week since the last time supposed technical specifications for the next-generation of consoles hit the web, so it’s high time for some more speculation surrounding the possible features and other technical bells and whistles you could find inside the box when Durango, Xbox 720 or whatever finally launches later in the year. That’s assuming that the speculation thus far is all true, of course.

The latest rumoured specs have the next Xbox sporting a dedicated Kinect port, an integrated ‘Natural User Interface’, an eight-core 1.6GHz AMD CPU, a 50GB 6x Blu-ray disc drive, a 500GB HDD and a whole lot more besides, according to a document obtained by VGLeaks that alleges to have the full tech specs for the next-gen Xbox AKA Durango.

You can check out the full list of specs and a ‘system block diagram’ showing how all the technical gubbins apparently fit together. Remember, this is all rumoured stuff however, and none of it’s confirmed.


x64 Architecture
8 CPU cores running at 1.6 gigahertz (GHz)
each CPU thread has its own 32 KB L1 instruction cache and 32 KB L1 data cache
each module of four CPU cores has a 2 MB L2 cache resulting in a total of 4 MB of L2 cache
each core has one fully independent hardware thread with no shared execution resources
each hardware thread can issue two instructions per clock
