But it achieved the same 1600MHz stable being undervolted and +50% power target added. It did this with less than around 280-290W which is a massive difference.
For power yes, but the average consumer doesn't overclock, or mess with voltage and power. We need launch day performance out of the box.
Even at 1600mhz after fiddling for hours, they barely managed 1080 performance.
If AMD overvolts the hell out of RX Vega it'll flop given the performance we know of so far.
