A new paper benchmarks the performance impact of confidential GPU inference on NVIDIA H100 hardware utilizing Intel TDX technology. The study found that confidential mode increased latency and reduced throughput for both Mistral-7B and Qwen3-30B-A3B models. Specifically, time to first token saw increases of over 20% and global token throughput dropped by approximately 20% for the tested models. The research indicates that while confidential GPU inference is feasible, capacity planning must account for these performance penalties and earlier saturation behavior in larger models. AI
