Give up and relinquish both mean to let something go, but in different registers. Give up is the ordinary, colloquial phrase — to stop trying or to surrender something (give up a seat, give up trying). Relinquish is the formal word for willingly surrendering a right, title, or control, usually with some ceremony (relinquish the throne, relinquish control). Give up is plain giving-in; relinquish is a formal, deliberate handover.
Both release something, which is why they overlap, but they belong to different levels of speech. Give up is an everyday phrasal verb — it stops an effort or hands over an ordinary thing, with a casual, sometimes defeated tone. Relinquish, from Latin relinquere ('to leave behind'), is formal and deliberate: it takes a right, a title, or control, surrenders it willingly and in good order, and belongs to law, office, and ceremony. So you give up your seat on the bus (everyday), but you relinquish your seat on the board (formal). Give up is plain; relinquish is ceremonious.
give up
To give up is to stop trying — the everyday, colloquial way to say the effort has ended. It aims at striving rather than things: you give up hope, give up smoking, give up on a dream, give up a seat. Where pursue presses on and achieve carries the effort through to its end, give up is the moment the pushing stops. It can mean a healthy letting-go of a habit, or simple defeat; either way, something that was being reached for is released.
relinquish
To relinquish something is to give it up on purpose — the formal word for a willing, often reluctant surrender of a right, a claim, or control. It comes from Latin relinquere, 're-' plus 'linquere', to leave: to leave a thing behind by choice. It almost never takes a personal object — you relinquish a title, a claim, the throne, command, not a person. Where forsake is emotional and desert is a betrayal, relinquish is calm and proper: the loss falls on the giver, and the thing handed over is left whole.

Both let something go — ask how formal it is. Give up is the figure who stops shoving the block and sits down: an ordinary, casual letting-go — the trying stops, or a small thing is handed over (give up your seat, give up trying). Relinquish is the king casting down his own crown for the next to wear: a right, title, or control surrendered willingly, formally, in good order (relinquish power, relinquish the throne). If it's plain and everyday, it's give up; if it's a formal, deliberate handover of a right, it's relinquish.

They overlap when an ordinary surrender meets a formal one — you can give up or relinquish a claim — but give up keeps it casual, while relinquish makes it deliberate and formal, fit for rights, titles, and office. Give up also covers stopping effort (give up trying), where relinquish, which needs a right or possession as its object, cannot follow.
