Hi, i´m going to buy a laptom and I want to use it also for render in Octane. In the forum I have seen some GPU´S rankings but there is no topic about which are the best mobile GPU´S for render in octane. I would like to know which GPU should I choose for my laptop.

Maybe some of you have information about it.

thanks!

Personally I have a GTX 550M in my laptop and I'd say it performs pretty good. Obviously laptop cards are nothing compared to beefy desktop cards, but you could look into eGPU solutions, where a desktop GPU is hooked up to the laptop to do the CUDA stuff. See if the laptop you're buying has an ExpressCard slot or Thunderbolt. My laptop doesn't have either, unfortunately, but hopefully a USB3.0 solution for eGPU will become available sometime.

Any thunderbolt eGPU devices(exteders, kits) available? As far as I know all of them are at concept stage..GUS, from Village, etc..

Fastest is 580m or rebranded 675m
- both based on Fermi architecture =)

I'm not sure whether it's actually available yet for Thunderbolt, but the bandwidth with it is massive so no doubt people are working on it. See this thread for eGPU solutions: http://forum.notebookreview.com/e-gpu-e ... ences.html

As for the best mobile GPUs at the moment, I'd say it's the Dual 2GB GDDR5 NVIDIA® GeForce® GTX 680M - SLI® Enabled, offered in the Alienware M18x laptop. That's the top model running in SLI in a laptop, which is extremely powerful for a laptop, but it comes with a huge big pricetag (expect > $3000). http://www.dell.com/us/p/alienware-M18x ... 701shopNow

680m is Kepler based and this architecture don't perform as good as the one before, Fermi.
For games yes, but not for rendering in Octane =) so don't need latest greates hardware =)..

Kepler, 6xx whatevers, still underperforms, that's true - another important bit of information regarding mobile GPUs - they are absolutely always underpowered when comparing to desktop counterparts, at least by 10-15% but you pay for mobiles more than desktop so extremely overpriced and underpowered, I know, I got a dell xps a couple of years ago, the first one with SLI with 2x 8700M - and my god, was it slow - especially since SLI is total crap and still doesn't work well on 90% games and at at least my laptop and desktop regardless of drivers and windows versions (played cod3 on my 590gtx in SLI - it continues to crash the game, wtf)
at least get a laptop with something like thunderbolt plug, and get external pcieX box, get a laptop for 1K$, and a external 590gtx, save a 1k$
