Yeah, good point. Not sure if the reality is there are significant differences. I understand that FE chips were supposed to be higher quality, but thought power phases of cards like the galax series were better. My aorus WB extreme sits at 2100 (sometimes more) but the reasons given for not boosting further are always ‘limited by power’ so wondered if that would be significant going forward. Maybe not, or maybe a bios flash would be an option but wondering if it’s a factor in deciding which card is the best choice.
The issue isnt so much as the power connectors or the chokes/phases used on the board but more to do with the locked down bioses. I know that, so long as you had great cooling, that flashing your 2080ti card with a bios that allowed you to give your chip more power did allow some people to get higher overall boosts. There was the Galax bios which was 380W and allowed you to up that to 450W using the sliders. But even the FE and standard cards were 70A 13+3 phase VRM so could handle the 450W so you didnt need all the special bits they put on their card, just sufficient cooling. You didnt need the "superior" or additional power phases the Galax offered.
A lot of people used the Galax 380W bios and managed to get 2160 from their cards and would then be hit by the voltage limit on the boards, rather than the power limit.
Point is whether your card could hit 2160 all depended on your silicon lottery. I know people who used the Galax bios and they couldnt even get 2100.
Nvidia has put really beefy power stuff on their 3080 FE and 3090 FE boards. Subject to bios limits, it will be able to handle however much power you want to give it IMO.
It honestly comes down to silicon lottery and cooling. Hence why paying up to £600 more for these "superior" 2080ti last time seemed mental.
