You might be ok with a T 7800. Freq is a bit better 2600 vrs 2300. Same socket, thermals and bus speed ...different micro architecture though ... Merom vrs Penryn so who knows?
I did some more research and it looks like Intel only made 5 T series cpu’s In the early 2010’s and I think this T-4500 is the last in series . I think that’s it for this 478 socket and motherboard !
