I don't recall any issues like that. I recall the reference 290 coming with new software to throttle clocks as it approached thermal limits, but never problems with power limits like the 480 appears to have.
I'd prefer the 480, of course, because of the TDP. Nevertheless, it's not hyper-critical to call the 480 a bit of a disappointment for not outperforming the 390 by a large margin considering it's roughly the same price. Die shrinks have always brought improvements to price, performance and TDP. This time around, we're only getting an improvement to TDP. No price improvement, no performance improvement.
I'm an optimist, but that's a downgrade from what we're used to seeing from die shrinks. I'm sorry, it just is.
