A new leak for the Playstation 4 (code-named: "Orbis") materialized from VGLeaks.com Monday. The specifications listed indicate a powerful console based on the AMD Fusion line of APUs that puts the CPU and GPU on the same chip.
The "Liverpool" system on a chip APU was outed as a PS4 possibility last year and was said be a 28nm manufactured chip running at 3.2 GHz. The specs below list the clock speed at half that.
It's unclear to us from the specs provided but it appears that the Fusion APU will be paired with a discrete graphics chip.
On paper, these rumored specs appear to be more powerful than the rumored next Xbox (aka Xbox 720) specs. However, Microsoft's next console would have the upper hand when it comes to memory if these specs play out.
It's worth noting that these specs somewhat contradict another leak discovered by Kotaku. While the GPU uses the same "Southern Islands" R10xx core, the CPU is listed as four "Bulldozer" dual-core chips. This is from a development kit though so it could be emulating the "Liverpool" 8-core design.
You can check out the full run-down of supposed specs for the PS4 below. Remember that, while these can be fun to read and discuss, there's a strong likelihood this won't be what we see in the final PS4 console.
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
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
