It used to be that desktop computers reigned king in the world of powerful computing, and to some extent, they still do. But laptops are pretty powerful these days, and in our experience, a lot of engineering companies have actually swapped over to them for resource hungry 3D CAD applications — But what if you still need a bit more power?
Well, [Kamueone] wasn’t satisfied with the performance of his Razer Blade GTX870m laptop, so he decided to hack it and give it its own external graphics card.
Now unfortunately this really isn’t quite a simple as running some PCIE extender cables — nope. You’ll have to modify the BIOS first, which according to [Kamueone], isn’t that bad. But after that’s done you’ll also need a way to mount your graphics card outside of the laptop. He’s using an EXP GDC Beast V6 which uses a mini PCIE cable that can be connected directly to the laptop motherboard. You’re also going to need an external power supply.
[Kamueone] ran some benchmarks and upgrading from the stock onboard GTX870m to an external GTX 780ti resulted in over three times the frame rate capability — 40fps stock, 130fps upgraded!
If you’re not willing to shell out for a reasonably powerful laptop it seems that there’s not a ton that can be done to boost your gaming performance. That is, unless you have an empty Express card slot and the right chipset.
[Phatboy69] recently put together an external video card for his notebook, with fantastic results. His Vaio Z128GG had an Nvidia GT330M graphics card onboard, which is decent but nothing to write home about. Using an Express card to PCIe adapter, he added an external Nvidia GTX580 to his system, and he couldn’t be more pleased with the results. While the card does take a performance hit when connected to his laptop in this way, he claims that his graphics performance has increased ten-fold, which isn’t too shabby.
There are many variables on which this process is heavily dependent, but with the right amount of tweaking, some great laptop gaming performance can be had. That said, it really does take the portability factor of your notebook down to about zero.
