Xbox720 Specs

In January 2013 , VGLeaks , published what it claims were technical specifications of the next-gen Xbox console, Xbox720 will be powered by an 8-core CPU running at 1.6GHz, alongside 8GB of DDR RAM.

The machine also boasts a custom 800-MHz graphics processor, which "can effectively issue 1.2 trillion floating-point operations per second".
The console also contains 8GB of RAM and a Blu-ray disc drive, which can read 50GB discs, 32 MB of fast embedded SRAM, as far as its connectivity goes, it has Gigabit Ethernet, Wi-Fi and Wi-Fi Direct networking.
Xbox720 The full 'leaked' specs are as follows:

Xbox720 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

Xbox720 GPU:

- custom D3D11.1 class 800-MHz graphics processor

- 12 shader cores providing a total of 768 threads
