*Spectrum and Amstrad both have a '''bitmapped''' display.
*while ZX spectrum has a quite basic 1bpp character based colour display, Amstrad CPC can be considered an upgraded CGA display minus the Character based modes (with 16colours modes such as the Tandy's own custom "CGA" had...).
*'''They have a similar screen size.''' But '''Amstrad CPC''' actually produces smaller pixels in it's "equivalent" video mode (mode 1). 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 window is quite smaller as on a spectrum and has a larger border because the pixels are slightly smaller.
