An overview of what appears to be the complete specifications for Microsoft's much anticipated next generation Xbox console has leaked by way of website vgleaks.com. The site does not disclose its sources for the data, however, many of the details have reportedly been corroborated by sources of Richard Leadbetter, editor of the more reputable Digital Foundry.

Here's the full list, which according to DF "suggests that the data is at most nine months old: factoring in how long it takes to create a console, the chances are that there will not be many changes implemented since then"

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:

• custom D3D11.1 class 800-MHz graphics processor
  
• 12 shader cores providing a total of 768 threads
  
• Each thread can perform one scalar multiplication and addition operation (MADD) per clock cycle
  
• At peak performance, the GPU can effectively issue 1.2 trillion floating-point operations per second
  
• High-fidelity Natural User Interface (NUI) sensor is always present

Storage and Memory:

• 8GB of DDR3 RAM (68GB/s bandwidth)
  
• 32MB of fast embedded SRAM (ESRAM) (102GB/s)
  
• From the GPU's perspective the bandwidths of system memory and ESRAM are parallel providing combined peak bandwidth of 170GB/sec.
  
• Hard drive is always present
  
• 50GB 6x Blu-ray drive

Networking:

• Gigabit Ethernet
  
• WiFi and WiFi Direct

Hardware Accelerators:

• Move engines
  
• Image, video, and audio codecs
  
• Kinect multichannel echo cancellation (MEC) hardware
  
• Cryptography engines for encryption and decryption, and hashing

Digital Foundary also notes that the listed Sata 2.0 HDD as standard is expected to be 500GB minimum, and points out that the console seemingly has both HDMI output, and input, opening it up to an array of video recording applications.

A specific port for Kinect connectivity also indicates that the motion controller sensor will not be built into the console, but also not be hampered by the USB bus as with the Xbox 360.

The next generation Xbox, currently codenamed Durango, is rumoured to be revealed by Microsoft in the coming months, ahead of a wider showing at the E3 2013 expo in June, in preparation for a holiday season 2013 launch.
