It's improtant that GPU threads support locking and control flow divergence and I don't want to minimize that, but threads within a warp diverging still badly loses throughput, so I don't think the situation I'd fundamentally different in terms of what the machine is good/bad at. We're just closer to the base architecture's local maximum of capabilities, as one would expect for a more mature architecture; various things it could be made to support it now actually supports because there was time to add this support
