World Exclusive: Orbis unveiled -

CPU:

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


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


UPDATE: some people is confused about the GPU, here you have more info about it:

Each CU contains dedicated:

- ALU (32 64-bit operations per cycle)

- Texture Unit

- L1 data cache

- Local data share (LDS)

About 14 + 4 balance:

- 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
