,→Vega GCN 5th gen
[https://www.techpowerup.com/gpu-specs/docs/amd-vega-architecture.pdf Architecture Whitepaper]
Vega cards were first released in 2017. Vega is the last in the line of the GCN Architecture: 64 threads per wavefront. Each compute unit contains 4x SIMD units, supporting a total of 40 wavefronts per compute unit (a queue of 10-wavefronts per SIMD Unit). Each SIMD unit contains 16 vALUs for general compute + 1 sALU for branching and constant logic. Each SIMD unit executes the same instruction over four clock ticks (16 vALUs x 4 clock ticks == 64 threads per Wavefront).
