Different results when running on CPU or GPU

I run denoising of an HDR image produced by path tracing on the CPU, then on the GPU. The code is exactly the same, with the only difference being in the device creation. Upon comparing the results, I observed an MSE of approximately 2.7e-7. Is this expected? The GPUs tested were the Nvidia RTX A4000 and RTX 2070 Super.

Yes, this difference is expected and normal.
