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.

Architecture

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
