Why GeForce gtx 690 render quality is poor than gigabyte gtx 780.

[Muhammad Farooqi]

Hi.
Last night i bought nvidia gtx 690 from a used GPU market. I was told and i read myself to that gtx 690 performance is far better than my already in use card ( gigabyte gtx 780).

I created a scene in 3ds Max 2017 with maximum complex models in minimum available time.

I set the rendering settings for 4k. And rendering time to 3 min in iRay.

Gigabyte gtx 780 finished it's task with pretty fine quality in 4.34 min...
But evga nvidia gtx 690 finished the same task in 5.2 min with worst quality image.


i read on following websites the 690 is better.. and almost on every 2nd website where GPU comparision is available 690 scores more..

2. https://versus.com/en/gigabyte-geforce-gtx-780-vs-nvidia-geforce-gtx-690

i'm a 3Ds MAX and Blender guy. Not interested in 3d games but a few.

Autodesk also certifies and recommends geforce 690 under professional Graphic cards.. and about 780 autodesk says .. "tested".

Please see 3rd page for 690 and 6th page for 780.
https://knowledge.autodesk.com/sites/default/files/file_downloads/3dsmax2017_GFX_Results.pdf

Also in the following video 690 performs hell fast..

but not mine..

My system configuration is as below..

Lenovo thinkstation s30
Intel Xeon E5-1660
24gb DDR3
Evga NVIDIA gtx 690
And
Gigabyte gtx 780


Please do suggest me if i should keep 780 or 690 with different configurations... Also how is it possible to get better performance with 690…?


BTW.. is the rest of hardware in my system fine and compatible with 690? does that effect ?

The 690 is two underclocked 680's so unless it uses both and/or SLI it's going to perform worse.

Thanks for the reply.. but..
if this is so.. why eveywhere it got better scores? don't they put information with comparison, benchmarking etc or just put the information reading from the box?

It depends how they configured their drivers. I mean a lot of games don't use SLI anyway but on the games that do use it (Battlefield series) the 690 will obviously do better.

It depends on the application used.

EDIT: It also sounds like your SLI could be off, so I'd check that too.

EDIT 2: This might be similar to your results.

wait what.. is there any 4GB too for 780? (off topic comments!)


No SLI is on, but do you think power supply unit can be an issue??

why autodesk certifies 690 but not any latest with more GBs of VRAM like 970 and even 780 is just in "tested" list in autodesk recommendations.. i'm literally very confused about 690's lower performance..


wait a minute... I just read about minimum PSU should in 750Watts.. but i'm using 600watts.. does that matter? if' 690 is working fine on 600watts.. should i need a higher powered PSU?

 

[Toothless]

If your PSU wasn't enough you would know by your black screen.

There are some 4GB 780s, i think it was EVGA that made them.

Should probably turn on SLI since that's like, THE reason for the 690.

 

[eidairaman1]

Oem powersupplies are bottom of barrel, i'd get one.

 

[MyTechAddiction]

Go to the nvidia driver (if you didn`t already) ,select your program and change all the settings to high or higest also check is Sli is enabled

 

[NdMk2o1o]

Does sli even work in 3ds max? Is there no setting in the program that you can specify to use both gpu's?

F@H

There are no 4GB 780 GPUs. Cards that end up with more VRAM than originally released are usually created by doubling capacity, in the case of the 680 we saw 4GB cards and in the case of the 780 we saw 6GB cards.

why did they put 690 under 'professoinal'!? it's still a geforce... also the driver version they're listing is 361.91, although i wouldnt want to run that due to the kernel security issue a couple months ago

i dont know if SLI settings have to do with max's rendering

those comparison sites are nonsense of course, read the labels of every item they compare, it's almost always irrelevant, at best you might see some almost-like-a-game-benchmark like 3dmark

the performance is one thing, but image quality sounds like a big problem if it's that different... either settings are wrong or driver is wrong or max is wrong, so once again cpu rendering seems to be proven to be the only reliable one

@Muhammad Farooqi You would have been better off with a new GTX 1080 and the latest driver. Those GTX 690s are still quite expensive second hand I should imagine and only have a 2GB effective frame buffer which is tiny nowadays, while the 1080 has a massive 8GB, along with that much improved Pascal GPU and no SLI issues.

eBay it and the 780 and get yourself a 1080. You won't regret it.

 

[Artas1984]

SLI performance has got nothing to do with image quality rendering. It's all about driver optimization. And buying a SLI card for graphical rendering, no-mater how relatively powerful it still is - never a good idea! If GTX780 does the job good, why the change then?

Sell that GTX690 and get yourself GTX1070 (GTX1080 is an overpriced overkill anyway).

If you ain't got money, buy a used GTX Titan Black - it would be the best choice for your 3DS Max, unless you can afford GTX1070.
