Feast your eyes on the first image of a reference NVIDIA GeForce GTX 1080 Ti graphics card, compared side by side with the PCB of the company's flagship (still) TITAN X Pascal. As you can see, the GTX 1080 Ti is based on the same PCB as the TITAN X Pascal, since the two cards are based on the same "GP102" chip (albeit with different core configurations). To begin with, the GTX 1080 Ti features 11 memory chips, compared to 12 on the TITAN X Pascal, on account of its narrower 352-bit GDDR5X memory interface. It makes up for the narrower memory bus with faster 11 Gbps memory chips, than the 10 Gbps chips found on the TITAN X Pascal.The main difference between the GTX 1080 Ti and TITAN X Pascal, however, is NVIDIA bolstering the VRM with a 2x dual-FET design. NVIDIA basically placed an additional set of MOSFETs and capacitors along all the blank traces of the reference PCB. This approach lowers the load on each individual MOSFET, in turn lowering VRM temperatures. It probably also enables a higher power-limit. NVIDIA also updated the reference design cooling solution with a new vapor-chamber base-plate. The cooler also exhausts through the entire width of the second slot in the card's I/O shield. This meant sacrificing the DVI connector. The GeForce GTX 1080 Ti goes on sale later this month, priced at US $699.

Should help the 1080ti run cooler, but AIB partners would probably take those measures themselves. Posted on Mar 6th 2017, 12:15 Reply

I am a supporter of removing the DVI connector for a larger exhaust opening, and think this is how it should be on all higher end cards from now on. There are plenty of very cheap solutions if you must have a DVI connection. Posted on Mar 6th 2017, 12:22 Reply

Steevo How long till we get watercooled versions? Already known to be compatible with EKWB Titan X(p) block so effectively, from start if you want to custom it. I imagine a huge initial premium for AIO from AIB, IIRC FWIW. Already known to be compatible with EKWB Titan X(p) block so effectively, from start if you want to custom it.

I emailed HeatKiller and they say that their Titan X(P) blocks are also compatible. Seems as though due to the near identical layout all Titan X(P) blocks will work. Unless of course you purchase a third-party card. I emailed HeatKiller and they say that their Titan X(P) blocks are also compatible.

I'm against of removing DVI, but I guess everyone has their own taste of needed connectors.



But I can't understand why from Radeon 290 series removing VGA signal was a con instead of a pro in the conclusion. Posted on Mar 6th 2017, 14:25 Reply

Silly question, would it possible to modify a 1080Ti and turn it into a Titan X (pascal) by just adding the missing RAM chip to the board and then modifying the BIOS where the converted Titan X could overclock better than a normal Titan X through the additional Mosfets and other additional circuitry components from the 1080Ti?



Just a simple observation I made looking at the two boards and surprised how the Titan X seems to have a lot less circuitry than the 1080Ti which will be the cheaper (too much marketing from NVIDIA I seem to see here).

Other note is that the board layout seems to be either very similar or the same where the Titan X shows areas of missing circuitry which is present on the 1080Ti.



I get that modifying a graphics card as described is not likely to be very simple (could be wrong).

Steevo How long till we get watercooled versions? It is surprising that these 250W+ TDP cards don't have watercooled reference models. What I really appreciated about the Fury X was the reference water cooled VRM+GPU.



It's also long past due that GPU manufacturers retire the blower motor, nobody likes them, they're loud, and they aren't effective at cooling.

At best it's a neutral. well the question is, is it still functional?

If its not considered functional by the majority and instead is in the way of what they would like to be able to do, its not functional and mroe a nuisance more then anything. well the question is, is it still functional?If its not considered functional by the majority and instead is in the way of what they would like to be able to do, its not functional and mroe a nuisance more then anything.

Edit: Added another point. 384 bit vs 352 bit on the 1080ti. Your best bet would be putting a titan x pascal core on 1080 ti pcb and hoping that the memory chip lanes are all connected + adding extra vram chip. These things are usually not that simple :P 384 bit vs 352 bit on the 1080ti.

Nice results ! For half the money you get missing MOSFETs on TITAN p and the same number of cores . This will work very stable and will not need to buy more expensive versions from the subcontractors. In Slovenia the price of the cheapest importer for TITAN p. is 1,500 € . GTX1080ti will be available for 699 € and 22 % tax . Better it will be to wait for AMD rilise GPU and then buy . How they feel customers of TITAN p. when they see this circuits on GTX1080ti you may think. Yes definitely cheated and robbed at the same time . I would think that they want in Guinness Book of Records with a bad attitude after years of this kind of relationship On such attitude may even rely from nVidia. We'll see how it will be another year . Posted on Mar 6th 2017, 17:38 Reply
