Is there a difference between iPhone 8 Plus camera and iPhone X camera quality

I currently own an iPhone 7 Plus and I love the camera on it. I love the portrait mode that allows me to take amazing pictures. However I always want to improve my skills and more importantly to me, the quality of my pictures. My question is this: Is there a difference in camera quality in the iPhone X and iPhone 8 Plus. I am referring to the main rear cameras and not the front facing camera which I know is better and has more features on the iPhone X. I am also not including iPhone 8 in this as I want to have portrait mode features on my device.

Thank you for reading and I hope to hear back from people with their opinions and/or knowledge.
