Look, we don’t really understand this stuff. But there’s noise coming from people that do which suggests this latest Xbox 720 tech leak is the real deal.
The numbers come courtesy of VGleaks (http://www.vgleaks.com/world-exclusive-durango-unveiled/). We shan’t try and editorialise these – just take a look at the list:
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
