The Sega CD was originally intended to equal the capabilities of the TurboGrafx-CD, but with twice as much random-access memory (RAM), and sell for about JP¥20,000 (or US$150). In addition to relatively short loading times, Takami's team planned for the device to feature hardware scaling and rotation similar to that found in Sega's arcade games, which required the use of a dedicated digital signal processor (DSP).

However, two changes made later in development caused the system add-on to become more expensive than initially planned. Because the Genesis' Motorola 68000 CPU was too slow to handle the Sega CD's new graphical capabilities, an additional 68000 CPU was incorporated into the add-on. Furthermore, Sega decided to increase the Sega CD's available RAM from 1 Mbit to 6 Mbit in order to compete with NEC's RAM expansions for their PC Engine system. This proved to be one of the greatest technical challenges during development since the Genesis' access speed was initially too slow to run programs effectively. The cost of the device was now estimated at $370, but market research convinced Sega executives that consumers would be willing to pay more for a state-of-the-art machine.
