UnverifiedIn a pure CPU environment (2018 Threadripper, under load), SteerTTS edge achieves an RTF of 0.053 with 4 threads (about 19x real-time), with first-packet audio latency of about 120 ms thanks to sentence-level streaming.86% similarUnverifiedKokoro-82M has a real-time factor (RTF) of about 1.9 on a 4-core CPU, meaning it generates audio slower than real-time playback.77% similarUnverifiedThrough request-owned speculative KV, in a DeepSeek-V4-Pro 1P1D, MI355X, concurrency-256 scenario, the average TTFT was reduced from 19.4 seconds to 15.1 seconds.74% similarUnverified在M1及以上芯片上，whisper.cpp运行base模型的实时因子（RTF）可达0.1以下，即处理速度是实时的10倍以上73% similarUnverifiedThe RTX 4090 has a theoretical FP16 compute performance of 330 TFLOPS, and the actual Decode speed for a 7B FP16 model is typically 50–60 tokens/s.72% similar
