*Spectrum and Amstrad both have a '''bitmapped ''' display.
*'''They have a similar screen size. ''' But '''Amstrad CPC ''' actually produce smaller pixels in "equivalent" Video Mode, as for the approximately same area the normal display resolution on the Amstrad CPC is '''320x200 ''' (mode 1) while '''ZX Spectrum ''' produces "only" '''256x192 ''' pixels. Amstrad's screen can be reduced in size to match the Spectrum's (256x192, in Mode1) but then the actual display wondow is quite smaller as on a spectrum, with a large Border because the pixels have a constant size.
*The size and aspect of the pixels in the Spectrum's bitmapped display are comparable to the pixels in Amstrad's mode 1 bitmapped display in that both produce approximately square pixels.
*The '''Spectrum''''s '''video ram ''' takes approx '''6K'''. *The '''AmstradCPC''''s '''video ram ''' takes '''16K ''' (approx 12K when screen is reducedto Speccie's resolution).
*The '''Spectrum''' has a fixed '''palette of 15 colours''' (8 colours with bright versions of each making 15 in total - LIGHT black is still black).
