Upgrading GPU on a laptop - Lenovo

I'm a technical kind of guy except I just dont know if it is possible to do or not with my laptop.
I have exchanged the power supply port because it was faulty so I know the inside of my laptop.
Question is if there is a way I can upgrade the gpu on my laptop? It's a Lenovo Y510p - i7 4770k with (2) Nvidia GT750M's and 16gb of memory. It's a great machine. I certainly don't want to buy a new one just to have upgraded graphics. I want to be able to play the Division as well as Star Citizen.
Also to mention, I have a 170w Power supply.

 

First off there's no way that's ur cpu, most likely a 4700mq, but second unfortunately while you can add a second 750m like you have I'm almost positive the first one is soldered so that there is no way to upgrade it. The only laptops that can upgrade their gpus have them in an MXM slot.

 

Unfortunately, it isn't. The 2 750m cards are as good as you're going to get in that machine.

 

Thanks guys, what about buying a video card adapter for my laptop? and using a better graphics card in that adapter?

 

I dont think it has a connector with enough bandwidth, you'd need thunderbolt 3 which that doesn't have.

 

Probably not.. You can upgrade the CPU to 4810/4910MQ however GPU wise, your pretty much maxed out.. There were some 755M GPUs out there for Y510p however they are just higher clocked 750Ms...

 

GT 755M also have GDDR5, that does give noticeable boost, but its still not worth the change in this case.

 

You can do that. Ideally, there would be an adapter to make good use of Lenovo's proprietary Ultrabay PCI-E 8x connection, but I'm unaware of such a product:

The proven option is to use the bandwidth limited mini-PCI-E 1x connection to connect the external GPU adapter, but you'd have to remove your laptop's WiFi card and use a USB WiFi since the laptop only has one mini-PCI-E slot AFAIK. You'd also lose some of the external graphics performance (e.g. 10-20%), but it could be well worth it. Here's a thread with y410p:

The third theoretical option might be to make use of that M2 NGFF slot if it supports PCI-E on that laptop model and not just SATA. It seems to be possible to use it for external graphics cards at least on some laptops:

For what you would have to spend in time and money to purchase an external GPU (with no guarantee that it would work), you may as well save a bit more and just get an entirely new notebook.

That's certainly an option, but the "a bit more" part is debatable. E.g. a Nvidia 970 card is like $300 plus the external graphics adapter which is around $60 (postage included) and you get the performance close to the stock 980M level (given the bandwidth limit). How much is a matching 980M laptop minus the money he'd get for selling the used Lenovo (which probably won't go for too much)?

Regarding the risks, yes, there are no absolute guarantees that it will work, but I've posted a link to a forum where some owners have managed to connect an external graphics to a Lenovo y410p and y510p with no fuss apparently.

 

Do you guys know to what extent this bandwidth limit will affect the GPU? How do you calculate it? And does it make a cap, or will higher end GPUs still perform better than mid-end? I'm looking forward to buying a Sapphire RX 460, 2gb or 4gb.
There is an ultrabay adapter that will come back for sell in january for Lenovo Y510P ( https://www.techinferno.com/index.php?/forums/topic/9686-y510p-ultrabay-graphics-card/) but I'd like to start now. Plus, a universal adapter would allow me to do this egpu thing on future or past laptops.

Thanks if you can help!

 

If your mini express card runs at 2.0 4x speeds, you could run a Maxwell card like a 960 with only about a %10 loss of performance. The problem is going to be finding the hardware to accomplish this, as I know of none that support video devices. Also the pci express alone does not support the transmission of video back through the connection, you would HAVE to connect the video card to an external monitor.

Last generation video enclosures usually embraced thunderbolt 2 and stuck with cards like the 750gtx.

I would hunt out a modern laptop with a thunderbolt 3.0, still rare on mid level laptops but atleast it is a connection type that makes external graphics easy.

EDIT: So heres a simple solution that does exactly this.. BUT it seems to be limited to 1x. Maybe the mini express ports are 1x then? Unfortunately it hearkens back to 750gtx land and thus not an upgrade for you.



again... another video..still sticking with 750 cards.
