[EVGA]GTX 1080 only support 2-way SLI - But better SLI performance than before (With HB SLI bridge) - Page 44  

post #431 of 471
The thing that people need to remember that Jay like others out there are providing information to en entire audience that are not always tech savvy. So he may need to dumb out tech talk a bit to help those people out there understand were he is coming from. ***** he may not be strong in PSU hardware or some area out of his expertise because yes he lack the skill set for those. However; like others have said, he is just a regular guy just like you and me and others out there. I think that people forget he is good at what he does no matter what which is presenting a product and talking directly to a camera.

For example if people talk so much trash about him and other out there in you-tube why not challenge your self to be one of the top 5 tech people in you-tube? Since you know it all... lol
I mean don't do it for the money but to educate others in a better way and try to see how far you can grow your fan base. The true is not everyone can and it takes a special person to do so. The sad part of it is that I guarantee you that people will come in here and say you lack those areas of expertise or that you are not providing all the information of a product etc.... Note: YOU CAN'T Please everyone!. Sad story but true no matter how much of an expert you are or good at presenting yourself on you-tube or public speaking. biggrin.gif

People will always find a way to trash talk about you, or to prove you wrong etc....

I myself a good at what I do for work but when I get into forum I suck at writing, or explaining stuff I know well. biggrin.gif I am sure I would also suck at talking to a camera for you-tube. I would need a few beers and then... well you know. lol drunken.gif

Yup, find out that you might as well have considered it a waste of money because nvidia hasn't set up the process for getting an enthusiast key and refuses to give timelines as to when you'll be able to do more than fold or run BOINC on all of them at once. Until people can actually source out SLI hb bridges at their favourite retailer and/or be able to activate an enthusiast key it's vaporware. Harsh words, but if something new that brings about unlimited cosmic energy better SLI performance (as well as a soft lock system for those who want to run three or four cards) one would think that not only would you have such in reviewer's hands before the nda lifts but also have plenty of them on hand for the launch,and then use it to sell even more hardware.

Instead we get a tease, followed a while later by reviews, and then eventually stock of the product people wanted to get but had to wait so long that hype died down and logic took over, since there was plenty of time for the early adopter fee to become rather despised, not to mention nine days after review nda lifts to contemplate whether the performance increase over one's current hardware is worth the expense or not.

Mate my 750W rated silverstone specifies 750W in DC output! This is no exception. So who is making the stupid mistakes here???

Jay, it's in his video about what capacity PSU you really need.

The NVIDIA rep confirmed some of my suspicions. Basically, with me driving high resolution displays at high refresh rates, I haven't even been using the SLI bridges in my setups. All of the data has been going over my PCI-E bus. This explains why in my demanding scenarios, the differences in performance between 8x and 16x PCI-E were noticeable. This also explains why those that have tested with 1440p/60 Hz and below haven't seen much difference in PCI-E speed performance. The SLI bridge was utilized.

So now in theory, with the new HB SLI bridge will handle all traffic between the two cards and the PCI-E bus will only handle GPU to CPU communications, and not also GPU to GPU communications. Under this scenario, the benefit of having each GPU on it's own 16x PCI-E 3.0 bus will be much less critical. 8x may very well be about the same performance.

Also interesting to note, really only 2-way SLI is supported and 3/4 way SLI is just for bench-marking. Since going forward developers will have to be involved with SLI support and 3/4 way SLI setups being a incredibly small percentage, I highly doubt much 3/4 way support in the future for actual games.

I highly suspect that with the new HB SLI bridge and those running dual 8x slots for 2-way SLI, such as on a 1151 MB, will see a performance/smoothness boost if they run demanding display setups. thumb.gif

This also makes having X99 for 2-way SLI setups less warranted.

That video supports my earlier assessment. Nvidia is splitting sli support into 2 branches - pascal and everything else. You know what will get support first and what will usually get it later rolleyes.gif The "better sli support" will only be relative to their older cards. Apparrently issues will start to appear above 1440@60 now for older than pascal cards for newer games.
Also I didn't like that junk about the old sli running out of bandwith (sli limit AB) and the pcie lanes getting all filled up (gpu bus useage AB,gpuz) and copper wires being unable to carry 650mhz with those ribbon cables but can if you pour more plastic on those wires wink.gif. Or that you started having troubles with sli over 1440p@60.
Nearly anyone who has Kepler & up sli can check their bus useage and sli limit alerts and run higher than 1440@60 and know that, as of today, everything is fine.

Maybe if they said that 4k@120 or 5k would have problems with sli that would be more believable since people haven't tried DP1.3 with the old sli yet, but people insisting a bunch of junk is true hurts nvidia's credibility on this matter imo.

Aside from supporting the HB bridge and discouraging 3+GPU setups, what's the difference? The software implementation of SLI shouldn't be any different, and 3+ way SLI was never a good idea for gaming. Transferring a frame over PCIE shouldn't take any more time than it does now.

Well comparing some 6 year old SLI bridges, the ribbon cable looks like it's 2 layers, one of which is ground plane, while the rigid 3 way bridge has at least 3 layers, with ground plane top and bottom and plenty of via stitching. The flat flex bridge also doesn't look like it has matched impedance traces, I can definitely see a new bridge handling higher frequencies. Have you ever heard of cheap DVI cables not working at high refresh rates?

I think the FCAT graph they showed was real, but it was certainly an extreme edge case with the resolution that high(3x 4k monitors).

Quite true. I've run into performance bottleneck issues with the older SLI bridges running quite demanding setups. Once you start sending some traffic via the SLI bridge, and some traffic over the PCI-E bus, that's why you have the large spikes as depicted in the NVIDIA slide.

Well comparing some 6 year old SLI bridges, the ribbon cable looks like it's 2 layers, one of which is ground plane, while the rigid 3 way bridge has at least 3 layers, with ground plane top and bottom and plenty of via stitching. The flat flex bridge also doesn't look like it has matched impedance traces, I can definitely see a new bridge handling higher frequencies. Have you ever heard of cheap DVI cables not working at high refresh rates?

I think the FCAT graph they showed was real, but it was certainly an extreme edge case with the resolution that high(3x 4k monitors).

In the video they implied that they were going to be changing the signal path for the new sli so it wouldn't go over the pcie as much for pascal, but that it would remain the same for the older parts, and that the data would actually be more like a video signal than before. That is a break and is incompatible as far as I can tell. And now there are 2 versions of sli to do.
If I was in charge of the sli support team, you know I would put the current products first priority.
And if pcie risers work, you'd think sli cables can. Or do sli cables have to handle way more data than pcie? It's a short distance so less noise and the frequency can go up inversely proportional to it.
I wonder how much of the 1080's total output could be handled by a 4 lane pcie riser if nvidia's drivers let it run?

Making more bandwith for sli and leaving more for pcie was going to have to happen eventually, but not for 4k@60 which I run.
I just don't like that my setup "officially" shouldn't work well when it has until now. But I suppose it will only cost $460 to replace my 780ti's with polaris so long as their crossfire works well.
