Pros & Cons

9 pros·4 cons across both

V
T
V

vLLM

+5-2

Pros

  • 2-4x faster throughput than standard implementations via PagedAttention technique
  • Supports NVIDIA, AMD, Intel, and specialized accelerators (Trainium, Gaudi)
  • Zero-copy deployment: run inference in 5 minutes with pip install + 3 lines of code
  • Native HuggingFace model compatibility without format conversion
  • Active community (35K+ GitHub stars) with weekly updates and 200+ contributor base

Cons

  • 15-20% lower peak token/s on NVIDIA H100 compared to TensorRT-LLM due to less aggressive kernel tuning
  • Requires 2-3GB more VRAM than TensorRT-LLM on same hardware for identical batch sizes
T

TensorRT-LLM

+4-2

Pros

  • 10-40% faster token generation on NVIDIA H100/A100 GPUs through hand-optimized CUDA kernels
  • Memory-efficient with 15-25% lower VRAM usage via in-place operations and fused kernels
  • Enterprise-grade quantization (INT8, FP8) with negligible accuracy loss (0.5-1%)
  • Multi-GPU scaling efficiency of 92% across 8 GPUs, highest in class

Cons

  • NVIDIA GPU-only: no support for AMD Instinct, Intel Arc, or consumer-grade hardware
  • Steep learning curve: requires 20-30 minutes to compile models, CUDA expertise needed for custom kernels

Frequently Asked Questions

5 questions

  1. TensorRT-LLM delivers 10-40% higher throughput on NVIDIA H100/A100 GPUs through aggressive kernel optimization. However, vLLM achieves 85% of TensorRT-LLM's performance while supporting 7x more hardware platforms. For NVIDIA-only deployments with extreme performance requirements, TensorRT-LLM wins; for heterogeneous infrastructure, vLLM is faster to deploy with comparable throughput.
