Activity Monitor's GPU History shows "Radeon Pro 560" on my 2018 15 inch base model MacBook Pro?

So I was using activity monitor and when I went to GPU History I realised that it was registered as "Radeon Pro 560" (this was my first time checking GPU History). Everywhere else it seems to be registered as "Radeon Pro 555x" (What I thought I was getting).

This is what shows in "About This Mac."

This is what shows in my GPU History.

Just to check, I ran 3 Geekbench OpenCL tests and found the results to be within 300 points of the Radeon Pro 560 GPU, 5000 points below the average of the 555x (around 11% lower than the average)

My OpenCL scores. Geekbench also recognises this as a Radeon Pro 555x.

The OpenCL Scores from the Radeon Pro 560. The scores are very similar.

So, is this some odd coincidence? And if it isn't should I be worried?
