Sources close to SDF have unofficially revealed the specs for the next generation Playstation codenamed Orbis.  Stay tuned to SDF for an exhaustive breakdown of these specs and how it compares to the Xbox Durrango.

LIVERPOOL SOC
- Custom implementation of AMD Fusion APU Arquitecture (Accelerated Processing Unit)
- Provides good performance with low power consumtion
- Integrated CPU and GPU
- Considerably bigger and more powerful than AMD’s other APUs

PU:
- Orbis contains eight Jaguar cores at 1.6 Ghz, arranged as two “clusters”
- Each cluster contains 4 cores and a shared 2MB L2 cache
- 256-bit SIMD operations, 128-bit SIMD ALU
- SSE up to SSE4, as well as Advanced Vector Extensions (AVX)
- One hardware thread per core
- Decodes, executes and retires at up to two intructions/cycle
- Out of order execution
- Per-core dedicated L1-I and L1-D cache (32Kb each)
- Two pipes per core yield 12,8 GFlops performance
- 102.4 GFlops for system

GPU:
- GPU is based on AMD’s “R10XX” (Southern Islands) architecture
- DirectX 11.1+ feature set
- Liverpool is an enhanced version of the architecture
- 18 Compute Units (CUs)
- Hardware balanced at 14 CUs
- Shared 512 KB of read/write L2 cache
- 800 Mhz
- 1.843 Tflops, 922 GigaOps/s
- Dual shader engines
- 18 texture units
- 8 Render backends

Each CU contains dedicated:
- ALU (32 64-bit operations per cycle)
- Texture Unit
- L1 data cache
- Local data share (LDS)
- 4 additional CUs (410 Gflops) “extra” ALU as resource for compute
- Minor boost if used for rendering

Dual Shader Engines:
- 1.6 billion triangles/s, 1.6 billion vertices/s
18 Texture units
- 56 billion bilinear texture reads/s
- Can utilize full memory bandwith

8 Render backends:
- 32 color ops/cycle
- 128 depth ops/cycle
- Can utilize full memory bandwith

Memory:
- 4 GB unified system memory, 176 GB/s
- 3.5 available to games (estimate)

Storage:
- High speed Blu-ray drive
- Single layer (25 GB) or dual layer (50 GB) discs
- Partial constant angular velocity (PCAV)
- Outer half of disc 6x (27 MB/s)
- Inner half varies, 3.3x to 6x

Internal mass storage:
- One SKU at launch: 500 GB HDD
- There may also be a Flash drive SKU in the future

Networking:
- 1 Gb/s Ethernet, 802.11b/g/n WIFI, and Bluetooth

Peripherals:
- Evolved Dualshock controller
- Dual Camera
- Move controller

Extra:
- Audio Processor (ACP)
- Video encode and decode (VCE/UVD) units
- Display ScanOut Engine (DCE)
- Zlib Decompression Hardware
