20w ago - Following up on the previous PlayStation 4
rumor, today the purported PS4 / Orbis final specifications have been unveiled alongside updated GPU details below.
To quote via VGLeaks.com (linked above):
LIVERPOOL SOC:
- Custom implementation of AMD Fusion APU Arquitecture (Accelerated Processing Unit)
- Provides good performance with low power consumption
- Integrated CPU and GPU
- Considerably bigger and more powerful than AMD’s other APUs
liverpool
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
All this info is subject to change in the future by Sony. We will give more detailed information about each component in future articles.
Welcome to PS3 News! Thanks for all you have done! Glad you are interested in games now (most importantly the playstation) 
...
because of that point, my ps3 will be the last road. I'll switch to next XBOX.
It's simply impossible to emulate Cell CPU on x86 CPU in real time. Putting Cell CPU as second to x86 is lame too because to much heat and high price. At the end, PS3 didn't die without PS2 BC. Most likely, very popular PS3 games will be re-released for PS4.
