iPhone XS/XS MAX, and iPhone XR's A12 Bionic chip is different?

I have a question, when you go to compare different iPhone models I went to compare iPhone X, iPhone XR, and iPhone XS to see all the differences they had just for fun. when you go to the information about the chipset they all use the iPhone XR and XS both have the A12 Bionic with a 4-CORE GPU in them, but when you scroll down a lot more further to see the chipsets again it will say the iPhone XR's A12 Bionic chip has one less GPU core then the iPhone XS's chipset..

Is this true or did someone just do a little typo when they were adding the phones to the compare list?
