Probably gonna do a single article comparing all them once they're out/in tom's hands.

Or they're gonna do entire company product lines to compare the differences between the coolers/ect.

I'm curious how long it'll be before new cards start coming out designed for it. According to the article, 4.0 will use a different connector than PICe 3, and older cards will be compatible with the new connectors, but not vice versa (new cards won't be able to use PCIe 3 slots.) If I understand correctly though, existing cards don't take full advantage of even the full data transfer capabilities of PCIe 3? Or is that no longer true with Pascal cards--is that the reason for NVLink?
 


I would be surprised if the GTX 1080Ti would even use up all of the PCI-E 2.0.

Someone will probably know the specs though, and I'll be wrong, haha.
 
i literally just posted a test of pcie 3.0 with the 1080 up about 5 posts!! so that question is answered now :)

a long time ago when 3.0 was coming out, i guessed that what would drive bandwidth needs would not be gpu's but rather storage. it did not take long for that to prove true. we see pcie storage quickly filling up lanes while gpu's don't even push a small portion of the bandwidth. (previous tests took titan x cards to x4 mode and showed almost no performance loss).

i will say the same thing about pcie 4.0 gpu's will probably never catch up to bandwidth available but storage options will catch up with it the same as it did with 3.0, as quickly as they can make drives fast enough to use the bandwidth. the nvlink is not really the same thing. 2 cards sharing data over pcie will be slowed by pcie. nvlink is a way to connect the cards directly so they can share data faster, much faster. not the same thing really as x16 lanes not being enough for a single card. we won't see nvlink on consumer cards anytime soon as it is just not needed. it's used for those super cards used for AI and science research and such.
 


Whoops, apologies, I should have paid more attention. :/ But I expect, then, that it'll be some time before we have to worry about newer cards coming out that are incompatible with older motherboards. Good to know.
 
it's an understandable question since people throw the word "bottleneck" around all the time in every situation. but the reality is that no card today will max out a pcie 3.0 slot. pcie 3.0 x8 = 2.0 x16. so that means an older 2.0 x 16 slots, like on amd fx systems, won't slow a new 1080 card :) that's good info to know.
 


I have one of the cards and took the top of the shroud off to have a look. Literally is identical to the pic of the Founder edition from the toms hardware review.

I didn't think to take any pictures : / but if you want I can. Its super easy to take the cover off.
 
i'll believe you :) i'm was already sure that was the case just wanted to wait form verification. that's good enough for me since this is a normal thing for card makers to do. plenty of cards out there that are reference pcb's with custom fans on them. helps keep cost down. i'll go ahead and change the info to reflect this. thanks for the heads up.
 


I used a handy site called nowinstock.net to get my 1080. They have a page for the 1070 as well. The site auto refreshes every minute and you can set it up to only alert you when a certain model comes in stock if you want.

http://www.nowinstock.net/computers/videocards/nvidia/gtx1070/

Right now looks like only thing in stock is the FE 1070 from nvidia.
 


A really handy link there. Thanks!

 
i have never seen that site before. pretty awesome. how accurate is it? if it's accurate i'd like to add it to the op to help folks find them cards.

anyone else have problems with newegg links form these type sites? can never get partpicker or other sites to work with the direct links. this site does not work either. :)
 
hhhhmmmm might just be something in my settings somewhere. amazon and the other sites work fine. but newegg direct links don't work for me. i have to go there and search manually to get the part up 🙁

still a nice resource, for those looking for these cards. i added it to the listings. hopefully it can help some folks get a card.
 
i found some UK prices for the non-US cards. most were found at overclockers.co.uk. i updated these into the first page they have most models listed and available for pre-order/back-order. a few were actually in stock so may be a place to check if you're on that side of the pond.

not sure the prices are going to hold up with the UK vote yesterday to leave the EU. seems a lot is in turmoil everywhere and with the pound weakening for a while, it will probably drive prices up for the short term. but the euro is also dropping so who knows what's gonna happen to prices.
 
not sure if this was already posted or not, so here it is (again?) guru 3d did a 1070 sli test with 2 MSI gaming x's like they did nor the same 1080's.

same story really. at high resolution it beats a 1080 easily. at lower resolutions, it get negative scaling and loses to a single 1070 or 1080. i'm sure things will change over time but this is how it is right now
 


What's a high resolution and what's a low resolution?
 


1440p/4k = high
1080p =low/standard

at least for all the reviews I've seen so far
 
yah sorry. basically 4k is only one really worth doing 1070 sli. but 1440p showed promise as well.

below that 1080p was not worth it at all. every review of either 1070 or 1080 in sli was negative scaling at 1080p from the ones i have seen.
