In Volta, each "SIMD lane" has its own PC, if that makes it more legit.

I admit I'm not really keeping up here, but if it has its own PC (rather than doing SIMT lane-masking), how is it a SIMD lane?

That sounds like manycore, not SIMD/SIMT, no?

Citation? SXM2 didn't look that different, and adding that many ports to the new instruction cache they added would be absolutely crazy.
