Again, it is a "Black Edition". In the TPU review on the 2070 black, it was one of the worst performing 2070s coming in dead last in fps achieved when manually overclocked among all 2070s tested by TPU. It is slower than 2080 Ti FE. Here's how the 2070s stacked up overclocking wise ranked by fps ... just under 6% from the EVGA black to the top dog.
Card / Core Speed / memory Speed / FPS achieved
ZOTAC RTX 2070 AMP Extreme / 2085 MHz 1990 MHz / 145.4 fps
MSI RTX 2070 Gaming Z / 2015 MHz / 2015 MHz / 144.5 fps
Palit RTX 2070 GameRock / 2040 MHz / 2020 MHz 143.1 fps
ASUS RTX 2070 STRIX / 2040 MHz / 1990 MHz / 142.7 fps
NVIDIA RTX 2070 Founders Edition / 2040 MHz / 1985 MHz / 138.7 fps
EVGA RTX 2070 Black / 2025 MHz / 1995 MHz / 137.4 fps
PCpartpickers current pricing on the Black is $1069.99 on amazon / $1076.98 on newegg ... still $200 cheaper than the Zotac Ti which is 14% faster than the Reference card. The MSI Trio led the Ti pack with 226.6 fps in the OC test closely followed by the EVGA FTW at 225.2 and the Asus Strix down at 225.0. The reference card was 194.5 OC'd. So we are we are looking at a 14% performance difference for an 18% increase in price for the Zotac.

As for the BIOS swap .. as always "not recommended" unless instructed to do so by your manufacturer.
We have watched the 2070 drop and to a lesser extent the 2080, now that AMD shot their volley, we can expect supply to catch up with demand and start seeing price drops. However given the Radeon's parity with the 2070 ... we can't expect too much. Eventually supply will exceed demand, and the better 300A GPUs will drop to $1150ish. At that point buying a AIB card is the better option than a $999 reference card. If the tariiffs go away that may get them under $1,000. Not something I'd recommend, but at least justifiable ... to an extent. The 2060 and 2070 are reasonably priced, I'm not there yet on the 2080 and the Ti.
