For the sake of my health (lol) I've always looked at Switch as a premium-ish handheld, with the bonus of boosted performance on tv output. This news actually doesn't bother me too much, as soon as we learned Switch was not going to be a trad. console box, we pretty much knew what the limitations were going to be with mobile tech.
That said, according to a respected poster on gaf, Switch could actually have more SMs, maybe 4 or even higher. 4 SMs at these clocks would perform the same as X2 with their full clocks. The reason I think its possible, is because Nintendo insists on calling Switch a "home console" first, so with a decent performance being a goal, not to mention , touted as close to XB1 like Emily Rogers has been spewing, Switch could have a custom build of 512 cuda cores that would only take up to 2w docked.. Increasing SMs is >>>> increasing clock speed, for battery life, according to Thraktor:
"Case 3: 4 SMs - Docked: 768 GF FP32 / 1,536 GF FP16 - Portable: 307.2 GF FP32 / 614.4 GF FP16
This would be on the upper limit of what's been expected, performance wise, and the clock speeds start to make more sense at this point, as portable power consumption for the GPU would be around the 2W mark, so further clock increases may start to effect battery life a bit too much (not that 400-500MHz would be impossible from that point of view, though). Active cooling would be necessary in docked mode, but still shouldn't be needed in portable mode (except perhaps if they go with a beefier CPU config than expected)."
