Could somebody test the K4000 for me with this 3D model?


#1

Hi,

I think about to buy a K4000 3GB and ask me, how much could be the improvement over my GTX 285. The test would be quite simple - open the bike model -> enable shaded display mode -> _testmaxspeed.

My GTX285 needs approx. 28s for this test (if I turn advanced GPU lighting off 20s ). A Quadro 4000 needs approx. 15s. I’m curious for the K4000. If somebody like, he could disable the advanced GPU lighting off too.

Thank you,

I have a Quadro 4000 (not K4000) with 2Gb, TestMaxSpeed here is 20 seconds not 15…

I spoke with Andreas today, who tested his 4000 and he disabled the advanced GPU lighting too, so he got the 15s.

i have GTX 780TI 3gb in testmaxspeed 12.29s
in shaded i got 90s
i have i7-4770 3.9ghz 8gb and gtx780ti 3gb

Yes. The older GTX cards are faster.

Here you are: Less than 11 seconds. But look at the sensors: it is CPU that bears main load, not the GPU.

the result above is with disabled the advanced GPU lighting
When enabled, the result is much worse, nearly 32s:

Only doubled speed by a ten times higher price (100$ for an used GTX285 vs. 1000$ for a K4000) … . :frowning:

There are no really big speed advantages of expensive pro cards and on the other side the speed of the modern medium GTX cards is to slow. At the moment nobody is happy, the semi-pro user and the pro-user don’t get what they want. When this situation will be fixed?

With GTX 660ti 3gb I’m getting 18 / 39 sec.

A HUGE advantage of the higher end cards is GPU real-time rendering. The new V-Ray 2.0 will give you some very nice previews in just a few seconds, all by using the CUDA / GPU processors. The Quadro K4000 has 768 GPUs if I remember correctly.

A single K4000 will also easily drive two 27 in (2560 x 1440) monitors. Its amazing for the price vs. performance.

Finally, hell yes, I would some day like my viewports to be more responsive for the price I am paying for these video cards. I am actually glad to see the other complaints on this issue so I don’t have to do it so often. :smile:

how to run the test ?

I run the test
12.29s


tnx
