Is unit2 operations faster than ulong in OpenCL on AMD GCN cards?
Which of the "+" calculation is faster?
1)
uint2 a, b, c;
c = a + b;
2)
ulong a, b, c;
c = a + b;
Specifically on RX 580 or Vega cards.

From the compiler team's feedback, it looks like normally speed should be the same, but register consumption can be higher with long type.
