Hi all and nice to meet you.

I'm looking into the Lenovo W-series laptop which is a core i-7 device with the nvidia quadro 2000M on board. Do you guys think this will be sufficient for relatively quick rendering in octane render or not? If you dont think so, what laptops/brand would you recommend I look at and do you think that a desktop rig might be a better way to go?

One note on the desktop route is that the reason I haven't really considered anything but a laptop is that mobility is extremely important for me. I need to be able to take my work with me as easily and as often as possible. However, if the desktop represents a truly enormous advantage then I might reconsider.

Lastly, how will octane's performance on the above device (the Lenovo Ws) compare with luxrender on the same hardware. I don't expect you guys to know specifically, but for those familiar with luxrender, it is painfully slow and the main reason why I'm getting a whole new system for octane.

Thanks in advance

hi Ceru,

We haven't tried Lenovo laptops yet, but we have tried a couple of laptops like the Dell's i7 XPS ones and an Alienware. Since octane uses cuda for graphic acceleration so relative to the gpu in them, you must be aware of the number of cuda cores featured in the laptop's gpus. the nvidia quadro 2000M has 192 cuda cores, while our humble XPS with a geforce 540m has only 96 cuda cores but it can perform between 1.46ms-2.60ms per second and if you have 69599 triangles it will take about 1 hr 38 mins to render at 1.46ms/sec. And while it's rendering the other apps might lag 2-3 seconds from its normal response time since they've got to share this gpu. In theory, the quadro with twice as much cuda cores as geforce 540m would probably render twice as fast.

if you are considering this to render at a professional capacity, it might be better to consider a desktop where you have more control over your gpus and a desktop would also present less issues using multiple gpus compared to getting extenders for a laptop

hope these info tidbits help out even just a bit...

Thanks for the reply

It looks like I may have to look into a desktop; though mobility is still an important consideration...

Cheers,
