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
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
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
Networking:
- Gigabit Ethernet
- Wi-Fi and Wi-Fi Direct
Hardware Accelerators:
- Move engines
- Image, video, and audio codecs
- Kinect multichannel echo cancellation (MEC) hardware
- Cryptography engines for encryption and decryption, and hashing

I expect some of you will like this bit:
- 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
What's this?
Hardware Accelerators:
- Move engines
The Durango console is designed to offer game developers modern hardware that is more powerful than the Xbox 360. It uses a familiar x64 architecture and tools, and compared with Xbox 360 development, will reduce development time and effort spent on performance optimization, Hardware accelerators, including "move engines" for common tasks, will be added to the console. Move engines can perform common game tasks like compression and decompression while moving data around the system. The console also has dedicated hardware support for common audio processing tasks that reduce the amount of CPU time that must be devoted to audio. The GPU provides considerable computing power and supports Direct3D 11.
Durango will implement different power states so that it can always be powered on, but will draw minimal electricity when not in use. The console will be ready instantly when users want to play, and will always maintain a network connection so that console software and games are always current. With this "Always On, Always Connected" design, users will quickly and easily enjoy their connected entertainment experiences, with no waiting for the console to restart or install updates.
Every Durango console will be sold with a new high-fidelity Kinect Sensor which will be required for the system to operate. The console will provide HD video, and will use new depth sensor technology to provide better screen resolution and less noisy depth data. Active infrared illumination will provide high-quality monochrome images even in low ambient light conditions. A wider field of view allows play in smaller spaces, and removes the need for a tilt motor.
System software will offer a full set of system API for Natural User Interface (NUI) and the API set will be an improvement to the corresponding API used by Xbox 360, Skeleton tracking, identity, and other NUI functions will be performed by the system, and for that reason, titles no longer need to allocate title resources to NUI.
The Durango controller will make the best-in-class Xbox 360 controller even better. It will have low-latency wireless connectivity to the console, and improved ergonomics, System interactions that use the controller will be simplified to make them easier for noncore gamers.
Every Durango console will have a hard drive, although its exact capacity has not been chosen. It will be large enough, however, to hold a large number of games. All games will be installed on the hard drive. Play from the optical disk will not be supported.
Durango consoles will have a Blu-Ray Disc drive, Disc media will be used for distribution, but during gameplay, games will not use content from the optical disk. An installation system is being designed that will allow gamers to begin playing while the game is being installed on the hard drive rather than waiting until installation is complete.
Audio output from Durango will be all digital - 7.1 discrete PCM output through HDMI and S/PDIF. Hardware accelerators will be included for decoding and decompressing common audio formats. There also will be a dedicated sound processor to perform common signal processing in hardware.
