980 Ti in a laptop?

Now when it comes to laptop purchase, i just can't commit to anything atm.
As many other of you, I read plenty of threads like "Should I buy 980 or wait for Pascal"-type of threads, but now i am concerned with even lesser question. Is it even possible that nVidia is not done with all of its Maxwell architecture line-up for notebooks?

I kind of don't want to buy a GTX 980 equipped laptop, with something along the lines of GTX 980 Ti- equipped laptop, being released in a few months later. That card is pretty significantly more powerful, but also more demanding.
Or is the TDP of that card just too severe for any possibility of it being placed on a portable platform?

My GTX 460M has gotten pretty derelict... But throwing money away on around $3500 -configured machine, makes me pretty stingy and worried.

 

Very unlikely. If you underclock GM200 to 980's power level, it might be worse than 980.

The most powerful within-reach mobile GPU right now is Fury Nano, which can fit into the non-MXM 980 form factor nicely. Unfortunately given AMD's state in the mobile market it won't happen.

 

Just get 980m sli. In SLI games, its better than 980 ti. As it looks right now, pascal is probably delayed to q3-q4 2016.

 

Do you think there will be no other upgrades to video cards, aside the soon-to-be Pascal generation?
Also, I am quite new to the scene, and not too tech savvy on the electrical engineering front

From what you said, did you mean that even if it was possible to place 980 Ti on a laptop, it won't be allowed to function even in its standard form, and would have to be lowered in power, as in "underclocked"?

Is it really?! Better than even 980 Ti?!

Though I did hear that 980m SLI is pretty high on benchmarks and 3D scores; I just see vast number of people complain about it being not-worth-it, due to poor support of SLI, and low number of titles within gaming atm.

Also, isn't the latptop SLI configuration causes even more heat than the ruckus around GTX 980 being hot?
Those jokes about frying eggs on the laptop are pretty discouraging.

 

We can't say what NVIDIA plans to do before Pascal, but personally I don't think you'll see anything worth buying.

You won't find a 980 laptop that can fry eggs. Those are reserved for systems with proper cooling.
Some would argue that Clevo P870D is the only system which can maintain desktop reference 980 performance though. Everything else comes at a bit of compromise. But they don't fry eggs.

It can be better than 980Ti if you only care about frame rate.
Latency will be worse. But many people claim they can't feel the difference.

 

You dont need to be an ECE to understand hardware. I get around 970 SLI performance with my 980M SLi. No, its not really that hot. Poor support for SLI? Its alright. If you want decent performance, single gm200 is not enough. SLI is nessecary imo.

 

Do you mean fcat? Usually SLI fcat is reasonable. Microstutter at low fps is a thing though. And no, I dont notice it. With g sync, I feel SLI setup is smoothier then single 780 ti. Thats with g sync though.

 

I don't know how reliable this guy is, but that FPS difference he shows, if pretty insane imo.
I guess I need to re-evaluate a couple of things.

 

The 980M SLI setup is powerful indeed. At its best, it is comparable to a single titan x. (Strictly speaking only when a game supports SLI.)

 

I mean rendering latency, the time between GPU instructions go out of your host CPU and the time the rendered result becomes ready for output.

It's very hard to isolate this time in actual black box style testing, but given how SLI/CF works (usually alternate frame rendering), it must be there. An increase in total input lag is also measurable.

 

I severely doubt in blind testings, one could tell the difference. A couple extra ms(worst case measurement) is not really noticeable.

 

That's an argument you hear a lot on the internet.

Unfortunately, human perception can vary a lot. Plenty of ACT/fighting and speed run players can often hit a single frame window, let alone seeing the difference.Network lag compensation modes are there for a reason.

The difference is also higher than "a few ms". For 60Hz doing two-way SLI/CF would result in 17ms lag in idea conditions. The longer queue needed for buffering frames from slave GPUs (which is always a bit out of sync) can drive that lag much higher. But if you don't see it and don't care, that's actually good for you, since you have more choices.
