Disabling GPU For Battery Life

Posted

Hello everyone.

i recently found a laptop with pretty good value. It's an Acer Aspire 3 with a Ryzen 5 2500U, so I thought it was a great buy for ~$650. But there's one problem. Acer had to include a Radeon 535 GPU that's half the power of the Vega 8 in the Ryzen 5. I'd pry it out with the board if I could.

So, will disabling the GPU help battery life? And by how much? Thanks very much in advance.

Acer Aspire 3 A315-41G-R4BW
Ryzen 5 2500U
4GB RAM

Radeon 535 Graphics (TDP is 50W)

But I think the aspire 3 has a shit TN display if i remember right

 

almost all of the current Ryzen 5 laptops seem limited in one way or another, a lot of new ones were just announced at computex though, or shown off rather. So some of them might be really good. There's also a rumored 45W TDP model coming.

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?

Isn't the iGPU the Vega 8? Not the Radeon 535? Not to mention the "G" in the model number (-41G-), meaning it has a dedicated GPU. By comparison, an Aspire 3 without a GPU is called A315-41.

None of the Ryzen APU laptops come with a dedicated GPU.

So there's misinformation in this page?
http://www.villman.com/Product-Detail/Acer_A315-41G-R4BW

 

Pretty sure something is wrong there, why would they put a dedicated GPU inside a machine that has less cores than the APU? It might have dedicated graphics, but it seems to me I'd be slower than the built in graphics, guess it's an asia only model?

You probably won't have any option to outright disable it if it does have one

But it looks like it has a horrible display anyways
15.6″ HD (1366 x 768) resolution

Look for something with a 1080p IPS panel.

Try and see if a local shop or something has one, because this chart seems like it would be accurate in that the dedicated GPU is slower than the integrated GPU

Yeah, it could be inaccurate. I did check a physical shop a few days ago. It turns out that the screen was 1080p. But I'm not sure if it's TN or IPS, and if there is a dedicated card. I should check it again soon.

The normal one comes with the 1080p TN display and just an R5 2500U

The Swift 3 has a 1080p IPS display, though at that price you could just get an i5/i7 + GTX 1050

Why would they put in a GPU that's worse than the onboard graphics?
