For anyone interested in how regular GPUs work, this report is
pretty interesting:
https://www2.eecs.berkeley.edu/Pubs/TechRpts/2016/EECS-2016-143.pdf
It explains how Single-Instruction-Multiple-Threads execution
units hides latency, by interleaving multiple threads. So, 8-32
execution units are working in lockstep, but the impact of stalls
are reduced.
The typical on-die Intel GPU seems to have 8 execution units per
slice and 2x 128-bit ALUs per execution unit.
