The XBox 720 Durango specs leaked

It appears that the Xbox 720 while still being a massive jump from this current generation (Including Nintendo’s Wii U) will still fall a little behind the Playstation 4 Orbis with the graphical power.

The xbox 720 will, much like the PS4 being using AMD’s new jaguar CPU technology, and just like the PS4 will be using an 8 core variant of the mobile based CPU’s (that will typically be found in things such as tablets and lower power laptops). The Jaguar CPU in the XBox 720 will mirror the specs of the PS4, also running at 1.6GHZ.

RAM is handled very different for the two systems, with the Xbox 720 touting 8GB of DDR3 memory, couple with extremely fast RAM that is apparently tied into both the graphics card and the North Bridge as a whole. This RAM, (ESRAM) will function as a rapid buffer that will allow the major components of the console to access it as they need it. This idea is an evolved principal to that which the Xbox 360 featured with the 10MB buffer of eDRAM, however that memory was only available to the Graphics systems of the previous generation console.

The graphics unit, on face values at least, appears to be slower than that featured in its rival, the Orbis. The Orbis uses an AMD 7970M (the M denoting that the device is the mobile variant of the card). The GPU will be clocked down to only 800MHZ for the Orbis (50MHZ slower than usual) and features only 18 of the Graphics Core Next compute units, as opposed to the 20 that is in the ‘full’ mobile version. The xbox 720 Durango cuts this down further still, and while it operates at 800MHZ just like the PS4, the GCN Compute units were cut down further still, to only 12. This means 1.23 teraflops performance by Durango, compared to that of  the 1.84TF found in Orbis.

Xbox 720 Durango Overall Architecture Design – Notice The 32MB of ESRAM connected to the North Bridge

 Below is a complete list of all of the features and specs known about the Xbox 720 AKA as Durango.

Central Processing Unit:

• x64 Architecture
• Eight CPU cores running at 1.6GHz
• 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

Graphics Core:
