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
PU:
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
