Rumored Next-Generation Xbox Specs Float About

Rumored technical specifications of Microsoft's unannounced successor to the Xbox 360, the Xbox 720, or Infinity, (or whatever it will be called) has been leaked.

According to the leak, the Xbox 720 will sport an 8-core 1.6GHz processor, 8 GB of RAM, an 800MHz graphics processor and a 50 GB 6x Blu-ray disc drive.

During the opening stages of January, Microsoft teased a major reveal for its 2013 E3 press conference, which is widely believed to be the Xbox 720. The console itself is expected to be priced between $350 to $400.

The list of purported Xbox 720 specifications are as follows. Keep in mind that these are just from rumors, and we won't know until the very day it is announced. But until then, it'll be fun to compare them against your favorite gaming PC configuration.


  • 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
  • Wi-Fi Direct

Hardware accelerators:

  • Move engines
  • Image, video, and audio codecs
  • Kinect multichannel echo cancellation (MEC) hardware

    If the specs are similar or better, games that port from console to pc won't be as bad as it used to be.

    8 Cores? I sense multithreaded games.... maybe.

    And maybe Intel would start to move the hexa-core processors into the standard i7s (instead of keeping them at the very high-end i7 range), and move the octo-core processors into the very high-end i7 range.

    Plus, AMD should be happy. Finally their Piledriver and the future Steamroller has some chance given their strengths in heavily threaded tasks.

    Sounds a lot better than the other rumours that have been spreading around lately.
