Rumored Next-Generation Xbox Specs Float About
Said to be powered by 8-core 1.6GHz processor and 8 GB of RAM.
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.
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
- 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

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.

If that is true, game developers will have to step up their multi-threaded programming by several notches.
There is no hyper threading; it's 8 physical cores.
Look at point 4 and 6 under the CPU segment, that screams HT hun.
4 CPU cores, 2 execution threads per core, that means 8 effective cores doesn't it? Doesn't HT desktop CPU's list 8 cores if it's a quad core chip?
Yes things can be optimized to take advantage of 8 cores but that takes time and money and development costs for AAA games are already really high.
that is odd...
I thought that any BD player can read single layer 25GB and dual layer 50GB disks.
so the BD player itself is NOT 50GB.
am I wrong?
About damn time I would have to say.
Previous was 512MB, at ~24GB/s.
Quite the improvement! This should VASTLY reduce loading times, and increase draw distance by several factors!
What about the hard drive?
