Why does the Evga 3080 ftw3 ultra have 3x8 pin connections vs the XC3 ultra that has 2x8 pin? They both have identical specs other than the ftw3 having about 55 more Mhz of boost clock.

The FTW3 has a much higher power limit. I believe it is 450w while the XC3 I believe tops out at 345w.Why does the Evga 3080 ftw3 ultra have 3x8 pin connections vs the XC3 ultra that has 2x8 pin? They both have identical specs other than the ftw3 having about 55 more Mhz of boost clock.
Product differentiation. The FTW3 has an XOC BIOS available that allows the board to draw over 450W of power, which 2x 8 pins cannot deliver.Why does the Evga 3080 ftw3 ultra have 3x8 pin connections vs the XC3 ultra that has 2x8 pin?

I guess what I'm asking is , if you OC the XC3 55 Mhz would you get the same performance as the FTW3?Product differentiation. The FTW3 has an XOC BIOS available that allows the board to draw over 450W of power, which 2x 8 pins cannot deliver.
PCI-E slot can deliver 75W.
6 pin can deliver 75W.
8 pin can deliver 150W.
The XC3 model will have problems drawing over 375W, the FTW3 models can theoretically draw up to 525W.
All else being equal, yes.I guess what I'm asking is , if you OC the XC3 55 Mhz would you get the same performance as the FTW3?
So your saying by OC the XC3 Ultra by 55 or 60 Mhz would not put it in the same class (performance wise) as the ftw3 ultra?The extra power lets the card boost higher so no the same true overclock frequency between the two cards won't necessarily be the same. The more expensive card will also have better cooling which will effect performance.
What I gathered from EVGA Jacob’s tweets is that EVGA doesn’t “bin” their FTW3 chips any further than just testing to ensure they are stable at their advertised boost clock (1800MHz). Which is below what the majority of Ampere cards are hitting anyway at stock (1900MHz+). They likely do more extensive binning on their KlNGPlN variants though if I had to guess.I suppose the ftw3's might be binned better?

Same. I've been waiting for months. Best of luck to you sir.This is the one I want:

Says coming December. Hopefully there won't be a run on these open loop cards but that's probably wishful thinking...
It is quite a bit larger than it's XC3 cousin:

I'm not trying to OC a FTW3 ultra. I would like to OC the XC3 to reach the ftw3's GPU boost clock of 1800 Mhz. The XC3 ultra's stock boost clock is 1755 Mhz. So with a 45 Mhz OC, which should be easy, I would get a FTW3 ultra performance for $100 cheaper.The difference you should be looking at is the potential max overclock and boost consistency of each card. The ftw3 has a whole lot more power overhead for overclocking. It likely has better cooling too, but I doubt you'll be taking significant advantage of the increased power limit on stock cooling.
If you are looking at stock vs stock performance then the ftw3 is probably not for you.

Yeah, this is more YMMV territory however. I understand it's all silicon lottery with the modern boost algorithms.The cards max clock is all silicon lottery. I've seen people with really nice 2 pin cards and crappy Strixes. And vice versa.
I'm drawing 530W on my shunt modded 3090 FE :/
PCIE slot is at 90 watts (the card thinks it's 68W) and if I re-tapped off the PCIE shunt mod, I should be able to reach 540W since then the highest of the 8 pins should trigger the new power limit.
The PCIE slot is triggering the power limit.
The plugs can handle more than is given. What is given is simply official max specifications.
It's not much different than me pushing 230W through a GTX 1070's laptop MXM port and it hasn't melted yet, when the port is "officially" rated up to 150W max sustained and 195W maximum burst (which is why 200W MXM GTX 1080's come with an auxiliary power connector while 150W 1080's do not).
I just OC my XC3 ultra to match FTW3 ultra performance. My fans are only at 30% and I can't even hear them. I'm sure I could go higher but whats the point. I like where it's at.Much to my amazement: I got the email from EVGA an hour ago and pulled the trigger on the XC3 Ultra. This thread was one of several things in helping me dial in that decision properly. Thanks, all.

Nice, there is still hope for me yet.A few weeks ago at least.

The real reason is that, thanks to social media influencers like Buildzoid and GamersNexus who do "PCB breakdowns" where they discuss the details of each board design, there is a marketing advantage to using a third connector on higher priced cards, in that those guys will talk about how robust the design is.Why does the Evga 3080 ftw3 ultra have 3x8 pin connections vs the XC3 ultra that has 2x8 pin?

I signed up for notification on release day and got my purchase link a few weeks ago. Still waiting on a 2070S to 3080 step up though. The XC3 is semi quiet although you can hear it under load when it’s being stressed. No complaints here.Nice, there is still hope for me yet.
