Après les specs techniques de la Xbox720/Durango la semaine dernière, VGLeaks nous livre ceux de la PS4-Orbis.
Nous aurions aimé savoir si la mémoire RAM évoquée ci-dessous est de la DDR5 ou non puisque sa rivale embarquerait de la DDR3.
Toutefois, rien ne confirme que la version finale de la nouvelle Playstation obtiendrait les caractéristiques ci-dessous tout comme ce qui concerne la Xbox One / Xbox 720.
En ce mois de janvier, nous avons eu moult rumeurs sur les specs techniques mais ce qui serait plus intéressant, c’est de voir du concret en passant par une annonce officielle et quelques aperçus des jeux !
Car l’E3 2013 est encore loin...
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
[Mise à jour] : VGLeaks a mis à jour l’article pour apporter quelques précisions sur le GPU.
Chaque CU dédié contient :
- 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
Render backends :
- 32 color ops/cycle
- 128 depth ops/cycle
- Can utilize full memory bandwith
