His was joined at the Blues by hooker Kirby Myhill.
Earle and hooker Myhill will both be moving from Scarlets to the Welsh capital.
The 29- year-old South African born-lock Earle have made 94 appearances for Scarlets.
Earle now qualifies to play for the Welsh international team.
Before joining the Scarlets in 2012 he played for Cheetahs in Super Rugby, as well as Griquas, Western Province, Boland Cavaliers and the Golden Lions in the Currie Cup.
Hooker Kirby Myhill featured for Llanelli RFC before making his Scarlets debut in 2011.
He has gone on to make 71 appearances for the region.
The 24-year-old is a former Wales Under-20 international.
He has captained his country in the 2012 Under-20 Six Nations and at the IRB Junior World Championships.
Earle and Myhill join Nick Williams, Matthew Morgan, Rhys Gill, Steve Shingler and Willis Halaholo as confirmed new signings for next season.
Coach Danny Wilson is fully aware of Earle and Myhill's qualities.
"George is a hard-nosed second row forward who is uncompromising and brings real physicality to any team he plays for, [while] Kirby is a talented player of huge potential who I feel can really develop with us,” Wilson said.
He added: "They are both good professionals who will add not only to the squad we are building here but also the environment and culture."
These signings really enhance the pack power ahead of next season.
