8xxm (mobile) performance?

[glimpse]

Hi, anyOne have 8XX range cards in a laptop? how about performance any other issues?
Looking for something at least 4GB of vRam, but I haven't heard anything about them & Octane..

any input would be very helpful =)

P.S. how about NVIDIA GeForce GTX 880M - 8 GB GDDR5 SDRAM, anyOne have any experience with it?

I am stepping stone to this discussion as they are in the process of buying a laptop that is equipped with a 880 m with 8g. What do you think?

Good question glimpse, especially I am ordering 3x780 6GB.

PS. Some comparison to 780

I use a GTX760M with 2GB VRam. It works fine.
The 2GB are enough for me. I use instancing a lot.
The 760M has 768 Cuda Cores, which I find OK for a laptop.

Stability is also good. Only If I drop below 0.04Ms/sec, then it crashes occasionally.

I have an 880m with 8GB in my Alienware.

I get Ms/s = 9.79 on the benchmark scene in DL or 2.44 on PT or 1.89 PMC.
This is with alpha shadows on.
With alpha shadows turned off, DL is 10.6 ms/s.

The laptop doesn't get warm compared to my previous laptop I have noticed.

What else would you like to know?

Thanks dan!! its doable but still..

Which benchmark scene are you trying? I noticed there are two benchmark scenes on the forums

That's really nice~~~
however,I've got this result in my single gtx680m(@954,2200),octane1.2,Alphashadow=off,benchmark scene
DL= 11.94Ms/s 0m50s
PT= 3.53Ms/s 2m49s
PMC= 2.70Ms/s 3m41s

not the best result, I can even oc to @1100,2400 , but I forgot to write down the result!

Would u please try to oc your 880M to about @1100,2400 or something like @954,2200 and then comparing the result??Thanks~~

Or, you can wait until September, looks like nv will release the new 980M , which is 3d mark11 X=4500 pt beast!!! But I guess the pricing will be a beast also

@Kevin

Sorry I'm not clear what you're asking for.
What does this mean?
"please try to oc your 880M to about @1100,2400 "
