* Fine Horizontal and Vertical hardware scrolling
* Blitter chip, same as in the Mega ST
* Stereo 8-bit PCM sound using DMA, with variable rate (50, 25, 12.5 and 6.25kHz). The Atari STE can play Amiga MODs, and with higher quality than the Amiga's 28KHz 28kHz rate limit. However, at 50kHz, it uses 60% of the CPU for software mixing. Source: [https://youtu.be/CqRt37xQpac High fidelity dreams (Atari STE demo)]
* 256KB ROM instead of 192KB, containing the TOS
* Four 30-pin SIMM-slots, for up to 4 MB RAM
