Does dual channel memory affect APU performance that much?

[DigitalDoofus]

So I recently decided it was time for a laptop upgrade (dual core I3 wasn't cutting the mustard) so I decided to go for a A12-9700p laptop I thought the extra graphics performance would be a bonus and so far its pretty good, after I decided to replace the wifi card as the one included wasn't exactly amazing I noticed that it had a single stick of 2400Mhz memory (8GB), from what I have heard in the past dual channel memory improves the performance of graphics that are part of the CPU module, is it worth investing about £50-60 in another stick of memory to help boost the graphics performance?

 

TL;DR: Is it worth getting 2nd memory stick to improve the speed of the APU?

It will definitely give a boost, if youre gonna be using the laptop for a while it'll be worth the money.

RAM speed is fluential on APU. RAM channel is more for the CPU side of the die.

agree with the ram speed aspect. I recently put together another apu rig and used 1 and 2 sticks of ram. there was/is a big difference between ddr3 1866 and 1333 running 1 stick and almost nothing to report running 2 sticks as far as being any more helpful.
