24GB of VRAM is enough to support productivity-level Coding Agent operations. Gemma 4 31B and Qwen 3.5 27B can maintain a stable output of 15 tok/s on a laptop, and even reach 36 tok/s on a desktop. This means you no longer have to pay for the latency and privacy risks of cloud APIs—your 3090 GPU can directly transform into a private model factory. The key now is whether this inference speed is sufficient to handle long-context code refactoring tasks.
