Performance

The original target of the RX Vega series was to compete with Nvidia's latest Pascal architecture. RX Vega 64 -> GTX 1080 RX Vega 56 -> GTX 1070

The performance is generally good, but when it comes to performance per watt, or PPW, Vega is outperformed by Pascal.

Hardware Accelerated Video

Key changes from Arctic Islands

  • New programmable geometry pipeline
    • Up to 2x throughput
    • Primitive shaders
    • Improved workload balancing
  • Tile based rendering
  • New low precision instructions
    • Half precision floating point with 2x performance
    • 8 bit integer with 4x performance
  • 15% higher clock speeds
  • HBM 2
    • 2x bandwidth
    • 4x memory capacity
  • New memory controller
  • Render back-end is now a client of the L2 cache
  • The instruction buffer has been enlarged


HBM 2

Vega makes use of 2 stacks of HBM 2 (High bandwidth memory).

single stack HBM 1 HBM 2
dies 4 + 1
4 dram die, 1 control die
 		2-8 + 1
2,4 or 8 dram die, 1 control die
Gb/die 2Gb 8Gb
total Gb 8Gb 16-64Gb
bus width 1024 1024
clock speed 500 MHz 945 MHz
bandwidth 128 GB/s 238 GB/s
