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 instructions/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
  • Bluetooth

Peripherals

  • Evolved DualShock controller
