because its a 8+6? like I dunno, a 1080ti?

Well yeah, this is a Titan/Ti board, but you've clearly convinced yourself so I shan't waste my typing trying to unpick your flawed logic.

What I will say though is this: it is entirely reasonable to expect 1080Ti performance from the 1180, but if Nvidia need 8+6 PCI-E to do it on a new generation then this is a backwards step. Winding the clock back to 700 series PCI-E power requirements better give us some insane performance at the mainstream level.

lol, its not a Titan. its 256bit! its a mid-tier card. ie a 2080 / 2070. 2080 is my guess.

some 1080ti cards were 8+8, one was even 8+8+8!!

It is a Titan/Ti board as you mention above, the reason for this is the Titan V already uses a 8+6 PCI-E setup and draws far more power than any new 1180 could.

Who says the Titan/Ti aren't dropping down to 256 bit?

and herein lies the problem. Conflicting information and opinion based on rumours and speculation.

You say it's a mid-range card because mid-range cards are 256 bit. I say it's not a mid-range card because we haven't had 8+6 PCI at the mid-range for 2 generations. Based on these two points alone, either you're wrong because Nvidia are lowering the memory interface on the top-tier cards, or I'm wrong because the power requirements of this new generation are significantly higher than before.

We won't know until the damn thing is released in Q2 2020.

my 970 was 8+6. mid tier.

256 bit Titan - so this card has 16gb ram? with a 8+2 phase? i doubt it

GDDR6 on a 256 bit bus could be very doable for the highend cards.

Having said that it could be a 16gb VRAM card with a 512bit bus. If someone with more knowledge than me about GDDR6 could step in here and clarify.

My Reference 980s are 6+6

We should not be comparing non reference cards to up coming NVidia reference ones. AIB partners sometimes really go overkill on the PCI-E specs as it is a selling point in the enthusiast market.

The bottom PCB is for a GTX1080TI.

Looking at the size of the GPU pads,this looks smaller than than the GP102 in the GTX1080TI,so is under 471MM2.

I estimate around 400MM2 to 420MM2 in size,just comparing relative sizes(roughly).

Interestingly the GM204 in the GTX980 was around 398MM2.

Just had a thought

People are assuming the above is a pic of the upcoming 1180 PCB, for all we know it is just a board purely for testing hence the overkill with PCI-E and NVLink/SLI.

I kind of said before it could be one for a commercial card!

True, but didn't we already see a supposed development/prototype PCB that had 3 x 8-pin and a bazillion fans on it?

But that's an AIB card. We're talking Nvidia reference design here, and we've not seen a 8+6 reference design for mid-range since the 700 series.

700: 8+6
900: 6+6
1000: 8

so why would the 1100 go back to 8+6? Unless, as I said, Volta/Ampere/Turing/Ephemeral/whatever requires some massive power draw at the mid-range? Which would be stupid.

In any case, we're going around in circles for no gain. We will know when the card lands.

NVidia would not limit themselves to a single PCB for testing/dev of new cards.

I also think at this stage of the game if we are going to see leaked pics of the new cards PCBs they would be fully populated with components.

its not a prototype, its already been registered with FCC/CE. only one reverse nvlink isn't a quadro or pro card..and not a Titan cos that makes no sense putting a Titan out before a 2080 and its not enough phases.

From what I understand of it cards have been registered not PCBs.

1080ti was 8+6. is this a 2080+? could be.

The + is referring to the extra you will be paying for a different paintjob.

NVidia gave the Titan V a gold coloured cooler and charged £2800. :eek:

hedgey · 3 Aug 2018 at 13:56

christ, this could be a GA104.

Crackers · 3 Aug 2018 at 15:37

Could be an aib partner board rather than the FE, as some 1080 aib boards have 8+6.

Most top of the range custom GTX1080Tis (Xtreme, Lightning, Kingpin etc) have 8+8 and 370W power delivery. And believe me, they hit 350W very easily.

Xan suck my H balls for crappy 15%

If it is the 1180 that's 15% on the 1080ti. Then they will bring out a 1180ti with more performance. So if your going for a 980ti to the newest that's a good jump
