Cycle accurate emulation is trying to perfectly emulate timings right down to per-cycle accesses. So each individual component is emulated at exactly the right time, in perfect sync, and so on, which has a high CPU cost. The speed of the emulation depends on the way cycle accuracy is implemented. Cycle accuracy doesn't necessarily mean 100% accuracy. Only if the emulator is implemented perfectly is it perfect. An example of a cycle accurate emulator not being perfect is higan [[Higan]] with the ROM Hack "Mario and Luigi: Kola Kingdom Quest," where on real hardware, the level title text has graphical glitches, where whereas those glitches do not exist in higan[[Higan]].
