VGleaks has recently posted up what they claim to be specs for the next gen Xbox which is codenamed Durango. The specs are rumored to include an AMD-provided CPU with eight cores running at 1.6GHz apiece along with 8GB of DDR3 RAM. The machine is said to use a GPU running at 800MHz and features a built-in hard drive. The Durango is said to include a ‘high fidelity’ natural user interface (NUI) sensor which suggests some kind of built in Kinect functionality.

Here’s the rumored Durango system block diagram;


The CPU;

  • 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.

The GPU;

  • 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.

The 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.

The networking;

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

The hardware accelerators;

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