NVIDIA Pascal Thread

[Stuka87]

Edit: Impressive showing for Pascal in The Witcher 3: Blood and Wine. Geforce GTX 1080 is 40-50% faster than Geforce GTX 980 Ti.

Thats an original reference 980Ti though. Not any of the ones that people have been buying for the last year. But the 1080 does do well in that game.

I'm done with CF/SLI.

It's all about the person using the situation. SLI's not really something you just "plug in and load drivers and go play". That may work for.. 60% of games but if we know what we're doing and willing to manually tune the SLI profiles, we can actually get near 90% of PC games to run using SLI and scale well, even if the nvidia profiles don't exist or aren't optimized correctly.

Just takes a little time and figuring out. It's not hard to do.

But I think the majority of people either don't know how to tune (no offense intended at you directly, guskline.. I'm generalizing everyone here), or can't be ass'ed in to bothering with it, and so SLI gets a bad rep.

It's actually very good and can benefit a large list of games if tuned right.

How do you tune SLI?

 

[kithylin]

How do you tune SLI?

Either edit the profile yourself directly with nvidia control panel, or use 3rd party software like nvidia inspector (which lets you edit a lot of things for a game's profile that is hidden in the control panel) and flipping through different SLI modes (there's more than one), sometimes forcing some games to run on some other game's profile to get SLI working.. doesn't always work but in general I've had a lot of success in getting games working (And having positive scaling!) that normally wouldn't use more than 1 card with nvidia's default load out for drivers.

Also the biggest benefit of SLI in general is higher Anti-Aliasing modes. You only get up to I think 16x normal and like 4x or 8x super-sample with single card. Using two cards you get access to higher modes up to like 32x normal 32x SS.

Also you get access to SLI-AA which with nvidia can run the anti-aliasing on both cards if you manually edit the profiles with inspector. Normally it just defaults to 1 card AA.

I've run a number of SLI/CF set ups but my goal has been to get single high end cards for both machines. I believe I have accomplished that.

I've run a number of SLI/CF set ups but my goal has been to get single high end cards for both machines. I believe I have accomplished that.

To each their own end goals.. for me I want a system (running windows 7 preferably) that can still run older DirectX-8 and 9 games and all the modern games as well. Ultimately I want an SLI setup that can be powerful enough for all the new games and as a side benefit I'll be able to force stupid high AA modes in to older games for the lulz because I can.

I think ultimately however I'm going to have to dual-boot windows 10 and windows 7 to achieve this in the same system but it'll work.

Right now just a single GTX 770.. I'm not sure yet what will happen.. I -WILL- be getting more GPU power before the end of this year some how. Either GTX 1060 or another 770. I won't decide until aftermarket board partner 1060's arrive and get reviewed.

Guru3D's GeForce GTX 1070 2-way SLI Review

Power consumption not that far from a single Fury X:

Kudos to MSI, silent cards:

[Aikouka]

I got an interesting e-mail in regard to my EVGA Step-Up request. Essentially, they said that the demand for the standard ACX 3.0-cooled card is too high, and that they're upgrading me to the SC model for free. No complaints here!

"Working" is not the same as working well. The percentage of games with flawless SLI (and crossfire too) is not 90%. Some games you can get scaling, but you get maybe 20-40%. Others, you can get scaling but you get flickering because the code isn't well suited to multi card. Others you will get other strange bugs, like in all the Paradox strategy games your tooltips appear for a second then disappear in multi card set ups (disclaimer: ive only personally tested this on CF, but from what I can tell it applies across the board, but this may have been resolved in patches postdating what I've heard). Many games don't support it on Day 1 or if they do support it day 1, there are still bugs related to SLI popping up. Unless there's some magic way of "tuning" out bugs in the game code, this sort of thing persists even with tweaking.

It's a major pain these days.

1280 SPs 192-bit 6GB
1024 SPs 192-bit 3GB

Die size should be smaller than 200mm².

That's about what most of us expected. A 192-bit bus paired with 7GB/s GDDR5 (the same type used on most Maxwell cards) would give 168 GB/sec, which is just over half of the 320 GB/sec on GTX 1080. That fits with the rest of the chip being basically half a GP104.

GTX 960 has about 53% the performance of GTX 980 at 1080p, according to TPU's numbers. If GTX 1060 has the same 53% of the performance of GTX 1080, which would make sense assuming these rumors are true, then that would put it about on par with R9 290 and GTX 970 - probably just a little bit below RX 480. Perf/watt is still to be determined, but if the chip is really that small, Nvidia might have a slight edge here. It won't be nearly as big a gap as in the GCN vs Maxwell days, though. Nvidia will have to price aggressively if they want to take midrange market share from Polaris 10.

It's not exactly half GP104 like GM206/GM204. We're talking 192-bit and 48 ROPs according to rumours (Ellesmere has 32 ROPs according to the recent GPU-Z leak). Even if it's only 1280 SPs at >1607 MHz (Geforce GTX 1080 clocks) it should be faster than Geforce GTX 970. Probably too early for performance predictions anyway.

Inno3D seems confident it will replace Geforce GTX 980 as well:

Inno3D seems confident it will replace Geforce GTX 980 as well

While it's true that the bus width is 3/4 that of GP104, a 192-bit bus with 7GB/s GDDR5 only gives 52.5% the bandwidth of the 256-bit bus with 10GB/s GDDR5X used in GTX 1080. If the GTX 1060 used 8GB/s GDDR5, that would increase to 60% of the 1080's bandwidth. But Maxwell and Pascal are already pretty good about making the best use of memory bandwidth; I expect GP106 is going to be constrained by shader throughput in most applications.

GTX 960 had the same base and boost clocks as GTX 980. My preliminary prediction for GTX 1060 was based on the same being true here with regards to the 1080's clocks. Existing GP104 chips seem to max out at 2050-2150 MHz on reference PCBs, regardless of whether an AIB cooler is used. If Nvidia decided they needed some extra performance on GTX 1060, they could presumably let the boost clock go up to a full 2000 MHz by default without hurting yields too much. That would likely match the GTX 980 in performance, but perf/watt would suffer a bit. Final clocks will depend on what metrics Nvidia thinks is most important.

Of course GP106 will replace all the GM204-based products. This will happen even if it falls behind GTX 980 by a small margin. Nothing says the products in a new line have to exactly match the performance levels in the old line, especially since GTX 980 was not a very popular card after the 980 Ti effectively made it obsolete.

Didn't see anyone mention this but thought it was clever that NV called its in-game screenshot capture software Ansel.

"Ansel is a revolutionary new way to capture in-game shots and view in 360. Compose your screenshots from any position, adjust them with post-process filters, capture HDR images in high-fidelity formats, and share them in 360 degrees using your mobile phone, PC, or VR headset."

"In newly released footage, legendary landscape photographer Ansel Adams recounts capturing one of his most popular images: Moonrise, Hernandez, New Mexico.

Adams' son Michael recently explained in an interview with Marc Silber of Advancing Your Photography how the events unfolded the day the photo was taken. Riding along with his father, he remembers how Ansel caught sight of the moon rising over the landscape and pulled the car over to take the photo. In the clip above, you'll hear Michael and Ansel Adams himself explain how the image was created, thanks to some quick thinking when a light meter couldn't be found. The resulting image is, of course, a classic."

Pixel processing on Pascal is limited by the number of GPCs. With GP104 it matches the number of the ROPs (4xGPC each can process 16 pixel).
GP106 will have 6 memory controllers (each has 8 ROPS) but only two GPC.

But these 32 pixel per clock are not a problem for GP106 over Polaris 10. With a clock around 1800Mhz GP106 can process 42% more pixel than a 480. And for Async Compute there is a low of headroom to be better than a 480 which has only 26% more compute performance.

I had a 1070 strix card on order from Amazon, I ended up cancelling it and getting an EVGA FE 1070 from newegg instead. I figure if I really end up not liking the card, I will use the step up program and get a 1080 card in a few months.

Not sure that's how step-up works. Check on the EVGA website.

I did, I didn't see anything that seemed to say you couldn't do that.

From the example on their website it seems that you can do it.

Graphics Cards

• EVGA will only release reference versions of its products, NVIDIA reference spec and clock, to the Step-Up program.
• Step-Up is limited to pre-approved graphics cards only and can only be used for exchange to a different and higher performing GPU.
• Products known to have a limited availability will not be made available to the Step-Up program. (Limited availability determined by EVGA.)
• Customers who received their EVGA graphics card as part of a complete computer system are not eligible - except for those listed on our approved system vendor list.

Graphics Cards Examples:

• GTX 780 Ti → GTX 980: YES (Upgraded GPU)
• GTX 960 2GB → GTX 960 4GB SuperSC ACX2.0+ 1GB: YES (Upgraded Memory)
• GTX 970 FTW → GTX 970 FTW+ : YES (Upgraded Model)

Did you go through the process and see if you could go from a 1070 to a 1080? I think the gpu upgrades are generally cross generation.

I remember having very limited options when looking to upgrade my 560ti to something higher.

I haven't and probably won't, but it's something I am considering trying incase it's possible. I'm sure I will be happy with the 1070 so it's not a big loss either way.

 

[JDG1980]

NVIDIA just moved forward the release of Geforce GTX 1060 by a month. It will start selling in the very near future.

Will it actually be available, though? Nvidia still hasn't nearly caught up with demand for the 1070 and 1080. Considering that they're clearly supply-constrained at this time, wouldn't it make sense for them to focus on the GP104 parts with (presumably) higher profit margins, instead of competing with P10 in the sub-$300 range?
