Rockchip RK3576 / Spark-X2.5 1.7B
Can a Rockchip RK3576 run Spark-X2.5 1.7B?
Yes, at a comfortable chat speed. Measured generation speed: 7.89–13.57 tok/s across 3 public runs.
Rule of thumb: 10+ tok/s feels like a chat; 4–10 is usable for assistants and automations; under 4 is batch-job territory. Speeds depend on quantization, runtime, context length and cooling. Check each source.
