System to boast 50GB Blu-Ray disc drive, more.

Video game leaks website VGLeaks has posted what it claims are specs for Microsoft’s next-generation Xbox, codenamed Durango.

First, the “system block diagram”:

Next, what’s “inside the box”:


  • 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.


  • 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

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


  • Gigabit Ethernet.
  • Wi-Fi and Wi-Fi Direct.

Hardware Accelerators

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

These specs seem to comply with previous rumors of the Next Xbox having 8 gigabytes of RAM, with 3 gigabytes reserved for the operating system.

VGLeaks promises a similar reveal for PlayStation 4, codenamed Orbis, soon. Be on the look out for that.
