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)

The PS4 will launch with a 500 GB hard drive, three controller inputs (new DualShock controller, dual camera and Playstation Move) as well as a Blu-ray drive speed of 6x on the outer half with somewhere between 3.3x and 6x on the inner rings of the disc. The rest of the spec leaks can be found below:

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

Sony is projected to make a formal announcement on the PS4 in the next several months. The next-generation system has an estimated release date of late 2013 in North America.
