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
