Noob question a GTX 560 Ti better than AMD APU A6-6400K Black Edition

[jpod]

Am I right in thinking a gtx 560 Ti (Zotac) is much more powerful than the onboard AMD gfx of an A6-6400K?

I think this is the CPU gfx

• Manufacturer: AMD
• Processor Line: AMD A6-Series APU
• Processor Model: A6-6400K with Radeon HD 8470D
• Cores: 2
• Frequency: 3900
• Socket: FM2
• Wattage: 65

AMD Radeon™ HD 8470D
DIRECTX VERSION DirectX® 11
GRAPHICS FREQUENCY 800 MHz
GRAPHICS CORE COUNT 192


This is the Zotac

• GPU GTX 560 Ti AMP! Edition
• CUDA cores 384
• Video Memory 1024MB
• Memory Bus 256
• Engine Clock 950
• Memory Clock 4400
• PCI Express Yes
• Display Outputs Dual DVI, mini HDMI
• HDCP Support DirectX
• DX11 SM5.0
• OpenGL 4.1

My understanding is that the 560 Ti is more powerful. Not sure why though in my noob role.

I understand "Graphics frequency" and "engine clock" are the same thing and similar 800 MHz AMD compared to 950 for the GTX, so slightly better.

And AMD has less cores, 192, compared with GTXs 384, I think that is significant in gfx prowess.

Have I understood that correctly? (Please explain like I am 10)

Thanks fellas

In case you are wondering why I use loads of spare parts to build rigs for nephews, cousins who are all starting their PC journey. So they can fix my PC in the future!

Yes dedicated GPU's will(should) always outperform onboard graphics. The 560ti is roughly 3-4x better than than this onboard you have.

APU's generally have limited memory and power resources (say 60-90w), while a dedicated GPU would have much more (150-200w).

The specs to compare are things such as memory bandwidth and memory bus. These values determine how much "work" can be done by the GPU at a time.

The Radeon HD 8470D has a memory bandwidth of 29.9GB/s and 128bit memory bus, while the 560ti has a memory bandwidth of 128GB/s and 256bit memory bus. This is where the major differences occur.
