bartimeaus Posted April 24, 2016 Share Posted April 24, 2016 I own a toshiba p50T and I am unsure as to what sort of performance hits I would suffer should I use a gpu. This is the specifications of my laptop http://www.mytoshiba.co.nz/products/computers/satellite/p50/pspmha-0ee04s/specifications So since it has optimus, I'm guessing I will be able to use my built in monitor to display the output from the egpu? Another thing is, I seem to remember there being a performance hit when you output back to your laptop monitor, does that still apply? Link to comment Share on other sites More sharing options...

Doink Posted April 27, 2016 Share Posted April 27, 2016 Yes, optimus will work and performance hit still apply. You will have x1.2opt means 1 lane with gen2 speed with optimus compression. You will get somewhere between 9-10k overall score (~11k graphics) with a gtx970 in firestrike using an external monitor. Link to comment Share on other sites More sharing options...

That doesn't sound like I have a huge performance hit from x1.2opt. Gtx970 gets about 11.k firestrike fhd in desktop configurations. If I use gtx970 with x1.2opt, if i get 9k, that's still 80% performance. Sounds great to me. Edited May 4, 2016 by bartimeaus Link to comment Share on other sites More sharing options...

But if you are using your buit-in monitor the egpu needs to copy back all the frames to your igp via the x1 link and thats another minus -10-20% depending on how havily taxing the game the pcie link.

Another Tech Inferno Fan Posted May 7, 2016 Share Posted May 7, 2016 If you want an easy way to figure out what connection speed your card is running at, run GPU-Z and Furmark (or a game or something). GPU-Z will show you the bus interface/speed. Link to comment Share on other sites More sharing options...
