The TileRT InferenceX article (Aug 10 2026) examines whether the TileRT software stack on NVIDIA GPUs can compete with dedicated inference systems such as Cerebras, Groq LPUs and SambaNova for ultra‑high interactivity workloads. It points out that while GPUs offer massive bandwidth—e.g., a 64 TB/s HBM ceiling on an 8GPU HGX B200—their kernel launch and synchronization overheads create sub‑millisecond latency bottlenecks that prevent them from meeting the low TPOT (Time Per Output Token) required by real‑time assistants like OpenAI’s GPT‑Live, even though theoretical throughput is far higher. Consequently, GPU‑based inference may remain competitive at moderate interactivity levels but falls behind specialized engines in ultra‑low latency applications.
