*Spectrum (48K machine) has 48K RAM, approx 6.5k of this is screen. The Amstrad has CPC464 and 664 have 64K ram, approx 16K of this is screen. *Latter Spectrum were supplied with 128K RAM (Spectrum 128, +2 and +3) and Amstrad CPC6128 was supplied with 128K RAM too (same amount of RAM used by Video as earlier machines)
*Spectrum and Amstrad both have a Z80 CPU.
*Amstrad has hardware scrolling, Spectrum does not.
* The Spectrum 48 didn't come with a joystick port, you had to buy one. There was two variants, Sinclair and Kempston, thankfully the hardware was cheap and easy to obtain, and both were well supported by software. The Amstrad came with a joystick port built in.
* The Spectrum didn't come with a tape player, you had to buy one. The Amstrad CPC464 had a tape player built in, however neither the CPC664 or CPC6128 had a tape player built in, you had to buy one if you wanted to use tape based software with them.
