[Performance] The 16-bit quantization QDQ model cannot be accelerated by CUDA

[duanshengliu]

Describe the issue

My GPU is V100 CUDA Version: 12.0 or 11.8 CPU is Intel(R) Xeon(R) Gold 6271C CPU @ 2.60GHz

I tested the performance of A8W8 and A16W16 quantization models on CPU and CUDA respectively. The performance of A16W16 quantization model on CUDA is even worse than that of CPU.

Summary:

Total Inference Time(s)（repeat=100）	A8W8	A16W16
CPUExecutionProvider	6.698 s ✔️	30.961 s ✔️
CUDAExecutionProvider	3.870 s ✔️	42.365 s ❓

Moreover, The A16W8 or A8W16 quantization models also have the similar issues.

To reproduce

This issue can be reproduced by using the relevant files in performance.zip. The reproduction commands and results are as follows,

cd path/to/performance
python run.py

then you will receive the following results:

mobilenetv2_a8w8.onnx ['CPUExecutionProvider'] Total Inference Time: 6.698 seconds
mobilenetv2_a8w8.onnx ['CUDAExecutionProvider'] Total Inference Time: 3.870 seconds
================================================================================
mobilenetv2_a16w16.onnx ['CPUExecutionProvider'] Total Inference Time: 30.961 seconds
mobilenetv2_a16w16.onnx ['CUDAExecutionProvider'] Total Inference Time: 42.365 seconds
