Hardware and speed Tweet

[3form]

Hi all

Thanks for all the feedback from the 3ds max exporeter page. I am about to purchase!!! just a few more q's mainly hardware.

I have a 9800GT and ordering a gtx460 palit 2gb for the rendering part. My 9800 gives me a 1sspx/10seconds in path. Is my calculations correct in thinking that the 460 is 10.5 times faster that the 9800 due to it has 336 cores vs 32 cores? or dies the 460's 2nd gen cuda and fermi make it faster than 10.5X ? Only asking this because I am looking at indigo that supports cpu and gpu but not my budget. and on indigo i get a pretty high number with just my cpu. Any thoughts? Oh yes and is direct light fully biast? If so pretty sweet that octane is both.

system specs:
Q8600 clocked to 3.33
4gb ram
9800GT

Cheers

Hi, i think gtx 460 is more than 10 times faster because of optimized render kernel for fermi cards and the 460 2 GB is far good for the money.
The gtx 560/Ti is faster as the gtx 460, this is more a buget question.
Go through this thread, there are benchmarks for many cards.

Btw., GPU only renderer are always faster then CPU/GPU renderer because of only parts of the render process are on the GPU and the CPU has to feed the GPU all the time through the slow PCI/Ram system.
Octane load all data in the GPU VRam and render then with full GPU power.
It is also a new render PMC render kernel for customers (in testing phase) for spectral dispersion and faster caustics and less fireflies.

How fast is the gtx 560ti? Compared with the gtx 580 ?

Thanks for that, order the card another q tried loading a simple scene with BB's carpet tuft using scatter and a octane error message poped up saying cant load scene to complex pls load less complex scene. Bit of a worry as I will be using for interior and product viz with some large triangles and complex geometry. Will instancing be supported soon? and optimizations?

Thanks

@3dform, i think it is a memory issue.

You could try to decrease the texture size, octane unzip/unpack the textures in VRam and a 4k texture is very big.
Geometry is not so much a problem, i could work with millions of triangles with my poor gtx 260.
No problem with the gtx 460 2GB i suppose.

@bravoddb, search forum for benchmark gtx 580,
here is the 560Ti:

The performance is dependent on cuda cores, have a look here:

Thanks for the info will wait for card and test then buy final.
