PCB Phases 1080 Ti range

[geordiejc]

Pulled this from Wccftech's round up of 1080 Ti cards.

The Zotac Amp as a 16+2 phase design - does this mean better power delivery therefore theoretical more stable overclocks? (temperature ceiling obviously)

thans for the replys guys.

your getting the power limit and voltage mixed up. Power limit is just purely how much wattage its consuming. the boards TDP basically. Say a card has a 100watt TDP and is hitting 99 watts when gaming its hitting that powerlimit. increasing the power limit in afterburner to say 120% means a extra 20 watts the card can consume. It's irelevant of what the voltage the card is running at. The voltage could be unlocked and you could have something stupid like 1.2 volts availible but if the power limit is soo low it does not matter. There is three walls with Pascal. Temp wall, Power limit wall and then the Voltage limit wall.

Now with the FE 1080ti cards you hit the Thermal wall first with overclocking. Put it under water then you remove this problem but you then hit the next one which is the power limit problem. you can increase the powerlimit but you will most likley still hit the power limit as its so low. (Shunt mod can help) AIB cards such as the Zotac which have 2x power limit will get around this thus meaning there is only the voltage to worry about thus meanining in the end your max overclock depends on chip silicon lottery as everyone is restricted by the same voltage.

Now with a better power delivery design and hopefully the silicon gods are nice to you it means you may get anywhere upto a extra 50Mhz overclock. With the zotac cards its going to provide much cleaner power to the memory and core so there is less movement in power delivery and voltage meaning things remain more stable. But its not going to make a massive difference if that's what people are looking for. Better off putting it under water and making sure it does not throttle because of how GPU boost 3.0 works.

Thanks for that in-depth explanation !

@Besty - I want a card which overclocks well on air at the lowest decibel. My 1070 (gigabyte G1) has horrific coil wine.

I ordered the Gigabyte Blower card, because OCUK had a picture of the G1 they upgraded the blower for free to the Gigabye Gaming G1. I also have pre-ordered the EVGA SC, EVGA SC2 and EVGA FTW3.

Having owned a 980 Ti Amp! and a 1070 Amp! i'm a real advocate of Zotac. The lack of reviews on the AIB 1080 Ti range is very frustrating. I hope some reviews come out over the next week or 2 because i won't be buying all 4 1080 Ti's - just one.

It feels like the 1080 Ti came out 3 months ago.
