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
 |
Preliminary Data! Information presented in this article deal with future products, data, features, and specifications that have yet to be finalized, announced, or released. Information may be incomplete and can change by final release. |
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 |
