SGLang vs TensorRT-LLM: Extreme Speed GPU Optimization Battle

Evaluating RadixAttention tree-caching against Nvidia kernel-level TensorRT optimizations.

Metric SGLang Nvidia TensorRT-LLM
Primary Innovation RadixAttention tree KV-cache reuse Nvidia deep C++/CUDA kernel compiler
Multi-Turn Agents Massive speedup on repeated context Standard linear sequence processing
Setup Complexity Simple Python & vLLM compatibility Complex engine build and compilation
Hardware Target Any modern GPU (AMD / Nvidia) Exclusively Nvidia GPUs (Hopper / Ada)
Best Suited For Multi-step autonomous agent apps Ultra-low-latency enterprise chatbots

◈ Architecture Recommendation

SGLang is faster for complex multi-turn LLM agent chains; TensorRT-LLM achieves peak raw single-stream token speed on Nvidia GPUs.
