Performance[edit]
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.

Process Technology[edit]
- See also: 14 nm process
Vega is manufactured on GlobalFoundries' 14 nm process.
Architecture[edit]
Key changes from Arctic Islands[edit]
- 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[edit]
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 |
