This model fits, but memory bandwidth is the part holding decode speed back.
Throughput will feel slow
Estimated decode speed is only 7.0 tok/s, so this is more of a technical fit than a comfortable daily-driver setup.
Prioritize bandwidth, not only capacity
If this workload feels slow, the next useful step is often a GPU tier with materially faster memory bandwidth rather than only a small bump in capacity.

Yes, RTX 4070 Ti Super 16GB can run Qwen 2.5 0.5B with a C grade (Runs well). Expected decode speed: 7.0 tok/s.
Qwen 2.5 0.5B (0.5B parameters) requires approximately 3.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 2.5 0.5B is Q4_K_M, which balances quality and memory efficiency.
On RTX 4070 Ti Super 16GB, Qwen 2.5 0.5B achieves approximately 7.0 tokens per second decode speed with a time-to-first-token of 27657ms using Q4_K_M quantization.
For coding workloads, Qwen 2.5 0.5B on RTX 4070 Ti Super 16GB receives a C grade with 7.0 tok/s and 131K context.
On RTX 4070 Ti Super 16GB, Qwen 2.5 0.5B can safely use up to 131K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
