3 or 4 way it's double the lanes/wires - so double the bandwidth
 
What galls me that they can't double the communication speed or boost it and put on a better connector - ie Sli 2.0
Nvidia has had time to conceive of an upgrade and handle signal processing to handle more bandwidth in the card...but can't handle a bit more on the Sli bridge

If your assumption that using 3 or 4 way simply doubles the wires and in turn doubles the bandwidth, then using 2 single bridges would have done the same thing. Sadly, that assumption is wrong as it didn't and doesn't double anything.

It has been stated that the HB bridge won't work with older cards, so best guess is the wiring has changed to actually double the bandwidth, and since it is currently only compatible with the 1080, I wonder if it has something to do with G5X (the nicely shortened name for GDDR5X).

actually there would be a few set lines locked to 5v or gnd (instead of normal signal - on the bridge)to indicate HB bridge - so the software/drivers can kick in and change the bridge config on the card from standard to HB
you might also use a few lines to help signal processing too
 
as a engineer and computer scientist id know quite a bit about this
i used to design hardware and VLSI chips - and wrote drivers for Nvidia cards
 
but my analysis would be correct - most of the bandwidth comes from doubling the lines

Then why doesn't it kick in with the old Bridge? If the 1080 can't use the old Bridge and the lines are run the same, that would denote. Ore than just simple lines, would it not?

Personally, I know for a fact they aren't going to give out wiring schematics all that easy, but I would like to see the change.

Your original statement says three or four way is double the lines, so double the bandwidth. When using a 3 or 4 way that would increase the throughput compared to a single finger being used, correct? No.. It didn't. Using both fingers in 2 way didn't increase any performance.

Or, am I misunderstanding what you're trying to say? Obviously there are greater changes to the new bridge, or it would be backward compatible.

Standard Sli

 
thats 1-1 pin all going to same pin numbers 2-2 and so on
 
and it doesn't matter if you install the bridge in the front or back sli  in 2 way
 
now saying that - some are data - some are hardware signal lines - ack/nack/control lines
you need 8 or 16 for data - that would leave 8pins for other uses - power gnd and control/flow
 
we know one is used for lighting a sli bridge  ie 5v otherwise lit bridge would change with activity
 
process lines could indicate send /receive data - or indicate data or address location
you could have 8 data and 8 address - but im assuming you use a control lines to specific data/address and use 16bits for both 
since i don't know all the particular pinouts it's moot
 
in 3 way you have double bandwidth but 3 cards

 assume  a hookup like this
 
1-------->2------>3 - and use 2 pins to indicate what card data sent to or address or command
1<--------2<------3      that goes for both directions
 
or option 2 you use a control line to indicate flow
and do only one flow direction - and flip when you want to do data/info the other way
 
 
4 way

 
 
however comes the problem with control.... sli works master and  slave and slavemaster 2 and slave 3
where slave2 is master over slave 3 and master can control slave 2
 
so i bridge used for control
down to double bandwidth/ 4 - control overhead
 
look at this from bandwidth perspective
using 1 bridge for 2 cards - normal
if it was possible using 1 bridge for 3 - 1/2 bandwidth...... for 4 cards  - 1/4 bandwidth
 
using 2 bridges  for 2 cards - double bandwidth - for 3 cards double/3 - overhead (close to normal bandwidth).... for 4 cards double/4 - overhead less than normal bandwidth 
and why Sli has problems scaling
you lose bandwidth as you add cards
 
 
the HB bridge would not need the extra control lines - this you can hang one high ie 5v and one low(gnd) to indicate to the cards and drivers a hb bridge
on the other cards the bridge would hang/fail the SLI
 
if you use regular bridges on 1080 would work normally

@Xavier Zepherious
3-way doesn't work that way. As you can actually use three 2-way SLI bridges (at least one has to be flexible!)
 
Card 1, FINGER 1 goes to C2-F1
C2-F2 -> C3-F1 (or F2)
C1-F2 -> C3-F2 (or F1, if F2 was already used)
 
Think of it as "Round Robin."
 
4-way SLI... is NOT round robin like 3-way... but instead a "2-way-2-way SLI."
 
Card 1 <-> 2 get a 2-way bridge
Card 3 <-> 4 get a 2-way bridge
 
pair 1+2 <-> pair 3+4 gets the third 2-way bridge (either 1 to 3 or 2 to 4).
 
~~~~~
 
As for this whole thing about master and slave... it's actually set in software.

You'll probably get the same answer as everyone else, lol.

*you posted while I was reading through the thread*

You only spent 10 minutes trying. I guarantee many other people have spent way more time trying and got the same information.

People need to just wait. It's not that far away and the review sites will be able to spill their guts.

This happens every time there is a generation release. Its so much fun. I am happy to wait and see the real benchies!! :)

Guys. There's no reason to harass EVGA over this. I'm sure they are going to let everyone know all the dirty details when they can based on the NDAs they had to sign from Nvidia. The card isn't even for sale until the end of the month, so knowing now versus a week before release isn't going to change anything.

The same argument with the *officially* unsupported SLI configs for the 700 and 900 series. Or people who use Nvidia Inspector to force AA and HBAO techniques not *officially* supported. Whats the point in doing anything that isn't officially supported? Those kooky enthusiasts! There ought to be a law...
Anyhow, it appears it is possible just not *officially* supported.

Card 1 <-> 2 get a 2-way bridge

Ah...the old *flexible* 3-way bridge routine.... I sense a come back...

Yeah, it may be awesome to get it working, but if it isn't giving you any higher performance in game it's pointless.

This does make complete sense for them to do this. The market value for people going 3x 4x SLI was not way up there. More coding, more SLI support means more money they pay their engineers. So, cut that back, and more money for the wise guys. Yep... Jen Hsun coming home with a fatter check and paying engineers less money. lmao...




That's often the hard part.  You have to remember that this is a business and it is costly.  Putting on the game developers where it should be has never worked out, either.
 
Sajin is a very intelligent individual along with many others here.  They get this, they just don't like it.  It is difficult when your area of use is 'attacked'.  In this scenario, there is no chance of it working itself through because they have now made it physically impossible with physics of the card and HB bridge.  We have to wait and see what they do with the higher end Pascal.


I wasn't really "attacking" anybody. Was only speculating that it makes sense to me they would cut back on going with 3x or 4x SLI. There is just not a lot of profit from the public to continue providing the feature(s). Their numbers probably showed a very small margin in sales with people going 3x or 4x SLI. For many people, it's not worth it. I personally wouldn't mind getting another 980 to go 3x, honestly...
 
For argument sake, it might matter for benchmarking to get the numbers, but from a gaming world, it's all about how much each GPU is being used. Lower gpu usage is better. It was always the argument that 3x or 4x does not scale well. Of course it wont. Look at the GPU usage on the other hand, and you will see a huge difference. You don't want your GPUs overworking themselves.

I meant Nvidia 'attacking' their usage by not supporting it or making it impossible, stalin.   I did not mean you.  Apologies for the misunderstanding.

I have returned after a 2 year hiatus to participate in a soon-to-be epic thread.  This lack of 3/4 way SLI is disappointing.  For what it's worth Sajin, I knew exactly what you meant when I read the title.  I'm still rocking my 4 Titans on 7680x1440.  I really enjoy the performance of one card/screen.  Was looking forward to picking up 3 of these, but it looks like I will wait.
 
Oh and hey everyone:)

What's the point in hacking it to work when it won't be optimized? 




The same argument with the *officially* unsupported SLI configs for the 700 and 900 series. Whats the point in doing anything that isn't officially supported? Those kooky enthusiasts! There ought to be a law...
Anyhow, it appears it is possible just not *officially* supported.


Yeah, it may be awesome to get it working, but if it isn't giving you any higher performance in game it's pointless.




Well of course, why state the obvious? If there is no performance gain, then by definition 'it ain't working' and would be pointless.

1080 supports 2,3 4 way SLi...the problem is that the HB bridge only works 2-way as of now - sacrificing any other card not getting any bandwidth - -
 
look at the bridge - a standard single sli bridge is 1/2 that size wide

 
HB bridge

 
Duh!! comes to mind here - - ie 4 way sli bridge.... in a 2 way config
makes for double bandwidth
 
that doesn't stop you from using a dedicated Physx or going double 2-way
 
if Nvidia was that concerned with bandwidth then make a NVlink connector for the cards or devise new SLI transit protocol..ie sli 2.0
 
 




 
Correct, essentially, they just made it two single ribbons, using both fingers at the same time between two cards for double the bandwidth.
 
What saddens me is that they finally decide to make some updates to SLI capabilities, and instead of getting rid of the bridge all together like amd did with the 290x, they just limit the cards to two for "high bandwidth" and use both fingers at the same time for sli.
 
Might give a boost to AMD if you can actually run 3 and 4 cards where the drivers are actually made for it and the 1080 is limited to two.
 
Also, anyone find it humorous that there are screws missing in that picture?

He's actually changed it twice now. I think it's time to move on from that. It's old news now.

LINUS from the Wan show just said Nvidia emailed him and said more than 2 way is possible they would send him the code. Dont ask me what the code is because I dont know.
