* The C64 has the VIC [[ASIC]] video chip. The CPC has the [[COTS]] [[6845 CRTC]] and an [[ASIC]] Gate-Array.
* The CPC is made from chips purchased from various suppliers, while the C64 only uses MOS chips. Demos have serious [[CRTC]] compatibility issues on CPC while such problems don't really exist on C64, except for the PAL/NTSC split.
* The C64 tape loading is done through interrupts so is not intensive on the CPU. The CPC tape loading is very intensive on the CPU.
* The CPC can do overscan easily and any pixels can be shown, the C64 can do overscan too, vertically can be done using interrupts but horizontally is processor intensive and only sprites can be displayed in this area.
* The CPC is made from chips purchased from various suppliers, while the C64 only uses MOS chips. Demos have serious [[CRTC]] compatibility issues on CPC while such problems don't really exist on C64, except for the PAL/NTSC split.
