if it was at least a trade off between them, vega56 1800mhs, rvii 2800mhs on monero, rvii is 50% shorter on computing performance than it was supposed to be and yet it costs 50% more, not worth, brainwashed trolls will make it to be worthy, trust me.
Give it time, Mr Doom & Gloom.
Unoptimised drivers, unoptimised miners - that's what we're mainly dealing with currently. Vegas were allegedly crap until somebody found out they weren't, remember?
Well the Radeon VII isn't running on a new architecture. It's essentially a Vega 56 on a smaller node with higher bandwidth and memory bus. The smaller node allows it to clock at the 2-2.1Ghz range giving it that big boost in performance. I doubt drivers will do much more than we are seeing already. The performance numbers make sense based on what we know from Vega 10 (which is essentially Vega 20 at 14nm).
