I'm not sure it's quite like a meme stock, it's dropping because their earnings were below what was expected.
Their sales of CPUs for personal computers dropped because the huge prices of memories discouraged everybody to make upgrades.
On the other hand, they sold every server CPU that they could produce, despite the fact that the AMD server CPUs are much better, but AMD also could not produce enough of them, so both AMD and Intel sold every server CPU that they could produce.
So their earnings in personal computers dropped, but their earnings in server CPUs have risen like never before, bringing a profit instead of the losses of the previous years (when they had to accept great discounts when selling server CPUs, to prevent their customers to buy better AMD server CPUs).
