32 GB unified · 200 GB/s memory bandwidth · Gemma 3 27B has 27.4B parameters.
Short answer

Best quantization for chat: 4-bit (14 GB of weights) on LM Studio. Generation: 8–11 tok/s, leaving about 7.7 GB free for your other apps.
How it rates for each workload
Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
