Hi, 

I was looking at Skylake-SP processor's PCI configuration registers and I saw that device number 2058 is for KTI.

I searched what KTI mean But I only got the full name is Keizer Technology Interconnect and couldn't get clear explanation about this.

It seems UPI's other name or code name. Is it right??

Is there difference between UPI and KTI??

Thank you.

It looks like "KTI" was the code name used in the development of the technology and that "UPI" is the "official" name.   It is not unusual for Intel's documentation to be incompletely updated in areas like this....  

I think it is safe to assume that these both refer to the same thing....
