The next-gen xbox codename Durango is comprised of two modules, each module contains four x64 cores running a single thread at 1.6GHz.
Developers can focus effort on content and features According to CVG:
“With Durango, a familiar instruction set architecture and high performance silicon mean developers can focus effort on content and features, not micro-optimization. The trend towards more parallel power continues in this hardware; so, an effective strategy for multi-core computing is more important than ever.
CVG also mentioned that Durango is said to utilise a D3D11.x 800MHz Graphics solution and 8GB of DDR3 RAM.
