NVIDIA Pascal Thread

[CakeMonster]

Would make sense cost wise. It wouldn't be too badly gimped b/w wise either, at least not compared to the previous generation with improved compression in mind.

1070's (FE) specs say it's based on PCI-e 3.0. So is it reasonable to buy the card for z97 chipset (i7 4790) with few PCI-e 3.0 lines? I've been configuring a new desktop and I was informed that 1070 on Haswell (z97) will not show all its capabilities. Could you please clear it up? It would be a pity to have to get outdated 970 GPU for z97...

 

[Deders]

Z97 boards are fully PCIe3 compatible.

Even if you used it on an older board with PCIe2, you'd still get all the GPU's features.

Unless you're getting a really good deal on the Haswell chip, you should probably just avoid it and go Skylake. Otherwise you're buying into a dead chipset with no future room to upgrade, and it will be slower. The skylake chips have come down from their initial ridiculous prices

Just to clear it up for you. If you want haswell for some reason, yes haswell has full PCIE-16x-3.0 for the entire GTX 1070 line.

For that matter, so does Z68 systems, And P67 systems. With a PCIE 3.0 CPU.

All 3 systems will also run PCIE-3.0 8x-8x for SLI too.

Guru3D - Gigabyte GeForce GTX 1080 G1 GAMING Review

www.guru3d.com/articles_pages/gigabyte_geforce_gtx_1080_g1_gaming_review,1.html

 

[Termie]

TPU has its MSI Gaming X review up: https://www.techpowerup.com/reviews/MSI/GTX_1080_Gaming_X/29.html

Based on this and the Guru3D review of the Gigabyte G1, I think it's pretty fair to conclude that no one is going to be topping the 2100MHz/67C of the 1080 FE promoted in the Nvidia announcement. That boost level was achieved running at a 60fps V-Sync. That's an artificial scenario that anyone who's used Nvidia cards recently is quite well aware of. Basically, it's a stunt. You can get your cards to go full boost without even coming close to hitting temperature constraints.

The $620 EVGA 1080 ACX may be the card to get. I expect it to overclock every bit as well as the $700+ cards, while also being very cool and quiet.

 

[guskline]

Thanks for the link Termie. Sent you a PM.

 

[kithylin]

Is anyone else completely under-whelmed by the 1080 performance? I don't know what I was expecting but I sure expected a heck of a lot more than what we got. And the overclocks are misreable.. most of the cards only managing +120 to +170 Mhz OC?

I guess the days of GTX 960's and 970's doing +400 Mhz and +500 mhz with just afterburner software and nothing else are long gone with nvidia now.

How many Mhz did the gtx680 overclock (not % ,MHz). That would be where to compare.
New process ,new architecture.

edit:
Looks like gtx680's overclocked like ~200mhz.I checked some early reviews.

quote:
"Therefore, our highest possible overclock we achieved in total out of this video card was 1228MHz consistent, with 85% fan speed and the highest voltage in the options box. The only thing holding back this GPU is voltage and custom cooling."


Its like deja vu ha?

Deders, Kithylin, thanks, for the clarification! That's what I've expected. The techie from a nearby PC store has tried to assure me that I have to buy 970/980 with Haswell. I've doubted it, but thought it has something to do with motherboard capacity required for 1070, but from your information it seems that unfortunately he just might trying to make me buy outdated GPUs from their shelves.

Just to clear it up for you. If you want haswell for some reason, yes haswell has full PCIE-16x-3.0 for the entire GTX 1070 line.

So if I get 1070 + Samsung 950 pro SSD PCI-e, there will be enough 3.0 lines?

Unless you're getting a really good deal on the Haswell chip, you should probably just avoid it and go Skylake. Otherwise you're buying into a dead chipset with no future room to upgrade, and it will be slower. The skylake chips have come down from their initial ridiculous prices

Suprisingly in my city i7-6700K costs even a bit cheaper than i7-4790K. The only reason for my Haswell consideration is Windows 7, I'm going to use on the new desktop (discussing it in General Hardware section). The above mentioned tech guy (whom I was planning to order the desktop building) said, that these days they only offer Haswell desktops for customers and refuse to build on Skylake.

Probably shouldn't have been - it is pretty well bang on what we've got the last 5 or so years from NV in terms of overall uplift Not utterly stunning but they definitely didn't carve it up either.

They'll keep at the iteration from here - big Pascal in a bit then into Volta etc.

There was to much Hype with the Nvidia paper launch, it was a let down after the cards release for me also.

It depends on the system. If you use a 950 Pro on Z97 / Haswell system, I think it will limit you to one video card (No SLI), and even then will drop the single video card down to 8x.

I think if you try and use 950 with SLI on two video cards it will disable all of the onboard sata ports and run both cards at 8x8x, or may not even work.

For a definitive answer.. I have a suggestion for you. Find the z97 motherboard you would like to buy, and then go find the manufacturer's website and either email them or open a support ticket and mention it as a pre-purchase question. Ask them directly what to expect trying to use a samsung 950 m.2 card and ask them if it will still do SLI with a 950 at all. It may not even have enough lanes to do that.

I do not know for sure honestly but the companies that make the boards would know 100% and help you understand that.

From a comparative standpoint the 980 Ti -> 1080 jump is well within range.

Looking at past reviews on TPU...

GTX285 -> 480 was around 30%
GTX480 -> 580 was around 10%
GTX580 -> 680 was around 20%
GTX680 -> 780 was around 20%
GTX780 -> 980 was around 23%

No SLI - only one 1070 card. Much thanks for the suggestion!

You learned this from one of the motherboard companies? I'd like to know for the future.

 

[Deders]

Just had a look at your build thread and I think your tech guy is a bit behind the times. I did have issues with the whole skylake platform at first, but that's what happens when you combine 4 new technologies (Chip/mobo/DDR4 and NVMe) with a brand new operating system. These issues have been ironed out and it works great.

I do see what he's getting at with the PCIe lanes, and although it won't limit any of your GPU's features, depending on where you place your potential 950 Pro, something is going to be slightly bandwidth limited.

But this shouldn't really matter. Limiting a PCIe 3.0 16x lane to 8x won't impede in game performance. Might add a second or 2 on occasional game loading times if the disk and CPU can actually feed the GPU fast enough to saturate the 8GB/s you would have if you used both of your main CPU linked PCIe slots.

A card with more Vram, like the 1070 would help here too as it won't need to swap data between the Vram and System ram if you were to need more than the 4GB (3.5GB, whatever) a 970 offers.

The limitation comes because the CPU has 16 PCIe lanes built in, and the board will have a few extra. How many are available will depend on how many are used up by the boards on board hardware.

Generally with z97, unless you use the 2nd main PCIe slot thereby limiting your GPU to 8x, the smaller slots will only give the 950 Pro 2x lanes instead of 4, which does reduce performance.

Have you looked into how much a 950 Pro would help you in your particular video editing scenario's? I can imagine it would help when reading from a large video file, but not so much when encoding, where the CPU/Ram will still be the bottleneck and the disk will most likely still be writing at a few MB/s for highly compressed HD video.

I think if you try and use 950 with SLI on two video cards it will disable all of the onboard sata ports and run both cards at 8x8x, or may not even work.

There is a lot of confusion about this. This usually applies to Sata Express based M.2 drives, not PCIe based M.2 drives like the 950 Pro, and even with Sata Express it only disables 2 of the on board Sata ports, and that is when there is an on board M.2 slot.

The 950 Pro will use PCIe lanes, not Sata lanes.

For a definitive answer.. I have a suggestion for you. Find the z97 motherboard you would like to buy, and then go find the manufacturer's website and either email them or open a support ticket and mention it as a pre-purchase question. Ask them directly what to expect trying to use a samsung 950 m.2 card and ask them if it will still do SLI with a 950 at all. It may not even have enough lanes to do that.

I do not know for sure honestly but the companies that make the boards would know 100% and help you understand that.

^This^

Edit: z170 and especially x99 boards are more flexible with their PCIe lanes.

Very interesting, but then why does the water cooled seahawk offer only 200w? And what overclocking tools did they use to get 291w?

Looks like 6+8 pin is the culprit, that & the (lemon?) chip!

 

[Deders]

pretty much all the aib's have at least a 6 and 8 pin, meaning 300W can safely get to the card.

The limiting factors for how much they will actually draw when overclocked will primarily be the bios programmed power limit, voltage, and of course chip quality.

The link in the post you quoted only has a handful of AIB 1070s having anything more than an 8pin.

www.pcgameshardware.de/Nvidia-Pasca...ce-GTX-1070-Custom-Designs-Uebersicht-1198014

The 291 watt max power draw, very likely in a stress test, indicates that the card isn't artificially throttling due to a power virus.
The other cards do, so there's not much else to infer from the chart on that page.

I was thinking of 1080's. My mistake.

It's still quite a drastic boost from 150W. Nearly double. Having run Furmark and Kombuster on my own Nvidia cards (the former is locked. The latter isn't) using a power meter, I'm familiar with the differences between the 2 kinds of power loads. Even afterburner won't go above the power limit set in the bios or overclocking software.

This is a very interesting anomaly. Most cards (1080's at least) are apparently blocked from going any higher than 1.25v. And a 108-120% power limit is the norm when overclocking.
