Possibility of having true desktop GPUs in laptop

With desktop CPUs becoming more common in gaming laptops, will it be possible to have desktop GPUs in Laptops with native desktop (PCIE X16) sockets.
I know there is GTX 980, but that is specially made for laptop. I am talking about buying a desktop GPU, getting rid of the cooler and shoving it in laptop.

What could be the problems:

Size: Existing MXM cards are roughly half the size of a desktop card. But on a desktop card the processor and vrams takes roughly the same space as MXM card, the additional space is mostly for PCBs and components that on laptops, are mostly part of motherboard. So this space can be saved and given to desktop card. More or less!

Power Draw / Cooling: Currently we have laptops like P870DM and MSI 980-SLI that support 200W and 260W of TDPs from GPUs. For reference the "rated" power for a desktop 980 is 185W and 980TI /TITAN X is 250W. I know real world power requirements are higher but still shouldn't this be possible specially with the new power efficient GPUs.

Please share your thoughts and expertise as I am just a noob in these matters.

 

For things like titan x, the tdp is not even close to the real power draw with an unlocked bios......

TDP is a spec for the cooler that can be subbed in as power draw sometimes...

 

There are so many problems with this idea...

I mean, how would you even get power to the thing?

 

What is the point. Although if this nvlink takes off then desktop cards will shrink to not much bigger than MXM 3.0B

Desktop cards have non standard heatsink mounts, that kills the idea instantly.

 

I know but nvidia website states these numbers as "Power Requirement (TDP)". And these numbers are not too far off. A 980TI does "on average" consumes 250W. Fully stressed it can go upto 350W.

A dual charger for P870DM can provide 660W which should be enough even for a desktop system. However cooling would be a problem. But may be a compromise halfway could be achieved as to what cards are supported (for example flagship non-TI cards)

The point is not to be on the mercy of ODM to decide what laptop peasants are worthy of.

Ah. I didt know that. So even the reference cards have non standard mounts? That could be problem, but I dont know, could some clamps be designed to accommodate a variety of mounts.
Also how do after market GPU cooler work, are they released for specific GPU models.

Yes you could design a universal mount but that takes space and weight.

 

The performance offered by desktop graphics in a smaller form factor (aka. laptop) is absolutely insane and I love the whole idea. But stuffing desktop parts inside laptops is a bit ridiculous, IMO. They should be investing in mobile GPU's more heavily and matching desktop level performance instead of trying to stuff desktop components inside laptops and forcing laptop manufacturers to redesign their systems to support them.

For example, it's entirely feasible to make a 1080M perform like a 1080, but they don't do it because of the profit margin desktop components offers is higher than that of mobile. Again, they're basically producing mobile GPU's with two hands tied behind their backs (purposefully limiting themselves). And that's perfectly fine. I totally understand why... Just hate to see it.

The mobile GTX 980 we saw in the Clevo P870DM is probably the closest you'll ever get to desktop parts inside a laptop.

 

Or you can just get something like this:
