The graphics card in on-die with the CPU. See below:

http://en.wikipedia.org/wiki/List_of_AMD_APU_microprocessors#.22Kabini.22_.282014.2C_28_nm.29

http://en.wikipedia.org/wiki/List_of_AMD_APU_microprocessors#.22Kabini.22.2C_.22Temash.22_.282013.2C_28_nm.29

Current CPU is a Sempron 3850, see 1st ref. above. New one would be an 
A4-5000, see 2nd ref. I just noticed that they are indeed different 
sockets, but both same family, jaguar kabini. NewEgg says the new CPU is 
2 GHz, above ref. says 1.5 GHz, I would need to verify that before 
trying anything.

My current graphics is running as vesa, no acceleration. Neither GPU is 
fully supported for 3D acceleration. Most 2D stuff works OK (browsing, 
streaming video). Current GPU is R3 (HD 8280), new would be HD 8330, 
neither supported AFAIK.
