It isn't clear what you're asking.  Your system is a third-generation (Ivy Bridge) Core design, as it always has been.

All the 5520s use the Ivy Bridge chipset and CPUs.

at first usb and network ,,etc was a panther chip . now they are 7 series/C203 . 

the customer service changed the lan board only , does the panther chip was on my old lan board and the new board contain a 7series/C203 chip 

so the chip changed ? watch the code i sent . i have highlighted with red the product line . 

they all was panther and ivybridge chip , now they are 7 series/C203 and third gen graphics 

the graphics was IvyBridge now its third gen graphics .

other was panther point chip . now they are 7 series/C203 . 

what is the different between panther point chip and the 7 series/C203 

No difference.  Sounds like your operating system simply reads the identifiers differently. 

you are right , the ubuntu live cd version was different from the ubuntu i had
