Kronos is a 65nm GPU and is used on the Tonasket motherboard and Jasper motherboards built in July 2009. No significant changes were made. The eDRAM was changed to Styx-65. Kronos has proven to be the most reliable version of the GPU.

Specifications

GPU (Gunga)

  • 500Mhz clock speed
  • 48 floating-point vector processors divided into 3 dynamically scheduled SIMD groups (16 each)
  • Unified shader architecture
  • 16 texture addressing units
  • 16 texture filtering units
  • 8 pixel rendering pipelines
  • Direct access to CPU L2 cache
  • C23 stepping
  • 65nm process

eDRAM (Styx-65)

  • 10MB 256GB/s eDRAM
  • Contains logic for:
    • 4-sample anti-aliasing
    • Alpha compositing
    • Color
    • Z/stencil buffering
  • GS21 stepping
  • 65nm process

Details

Kronos uses the Gunga GPU and Styx-65 eDRAM.
