Reproduction

1.Excessive GPU memory，0.12.0 trt-llm 37g GPU memory 2.0.8.0 trt-llm qwen1.5-7b only 17g GPU memory

Expected behavior

0.12.0 trtllm qwen1.5-7b has 37g GPU memory，I want this version to reduce GPU memory

actual behavior

0.12.0 trtllm qwen1.5-7b has 37g GPU memory，I want this version to reduce GPU memory

additional notes

0.12.0 trtllm qwen1.5-7b has 37g GPU memory，I want this version to reduce GPU memory
