What does my APU do?

[junii421]

I have an AMD A4-3420 APU and i wanted to know the difference between an CPU and a apu

Basically speaking, an APU is a CPU that has an integrated GPU.

Not a lot. Its just an amd marketing term for their product line that has a graphics processor built in

Intel do cpus with integrated graphics too, they just dont have a fancy name for it

An APU is a CPU with an integrated GPU. Neither one is very powerful.

CPU and APU are the same thing. AMD coined the APU term to describe their series of processors that have an integrated GPU, which uses GPU cores from their aftermarket GPUs.

Architecturally Intel Pentium and Core i3/i5/i7 CPUs with integrated HD graphics are the same, however graphically the AMD processors generally perform a little better.

So how much Vram does it give or how does it help?

None. it uses system RAM just like any Intel processor with an iGPU. Technically if you have a GPU once it runs out of VRAM it rolls over to your system ram as well.

With an APU theres a setting in bios that you can change to dedicate a portion of your system ram to the graphics processing. The default is usually 512mb, you can increase it up to 2gb but whatever you choose is then unavailable to the rest of your system

You can do this on an Intel iGPU as well, its not specific to AMD APUs
