Not really. Nothing wrong with them. If anything it's probably better since they can get the TDP down by a significant margin and being only 50mhz slower than a normal core wouldn't really change much in performance.
I don't see how there is an argument over it? Nothing is false about them.. it's limited by temps, clocks, power. Keep them cooler than it runs faster but if it hits it's tdp limit it backs off the clocks. With a water cooler it sorta takes out part of the equation but now has to deal with tdp as it's main performance limiter. It only has 2x8pins so is already limited in amount of power, so it's more than likely just now AMD tuning them to tdp and worrying less about temps. And if this is the case it'll be slower than 2 Fury X cores in Xfire. Although you could argue that even if slower, you are essentially saving so much in tdp you could add another Nano and it would end up being faster. They could counteract the lower clockspeed issues by using some higher clocked HBM too if they felt like they needed too.
Although even at max clock speeds and tdp isn't the issue like you think it is, still means it's slower than a normal Fury X since it has lower clockpseeds and everything else is equal.
