You have to contact the motherboard/laptop manufacturer and ask them what processors are compatible with their bios. Then, you can select from those. And, that is only possible if your existing processor is not soldered to the motherboard.
Note that the T5850 is an OEM processor. For more information, contact Samsung.
In my opinion, replace the entire system with something new(er) that has an 8th gen or later processor.
