Sponsored Links
87w 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

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.

I wouldn't expect it to BC with the PS3 seeing how disastrous the BC Ps3 was. I feel Sony wants to make it cheaper to be able to compete more effectively.

Sony, with all due (dis)respect... SCREW YOU AND YOUR PS4!! if i cant play my ps3 games on your new system, have to register my games online before i can play them (ppl with no internet are messed) then you wont get a single penny outta me... 

Ps: Ingame adverts? What the heck are you thinking? I dont want to see adverts while on loading screens and the likes...

Oh and an online pass to be allowed to use your new ps4 online (if not even be allowed to use it at all ).. Users buying a ps4 used are butthurt too once again...

But why are Sony choosing X86 over ARM? The fact that Sony is changing architectures so much recently must really annoy developers...

PS1 = MIPS
PS2 = MIPS
PSP = MIPS
PS3 = CELL/PPC
VITA = ARM
PS4 = X86 ?!?

If it's ever modded at least you should be able to play some PC and some old Xbox games... and have outdated inefficient architecture.
