SID able to produce sound without access to RAM (no DMA). CPU is only needed to set hardware registers (period, volume &c).

Synth mean you not limited to play but also to create (for example in algorithmic way).
Synth means acting as a source of waveforms. SID is a source of waveforms. Paula gets waveforms from RAM that CPU has initialised. CPU may run a software synth but Paula is just output device able to modulate the waveforms but not create them.
