The prices themselves come from the live search, not from a table. The 9800X3D is the Zen 5 8-core X3D part. The 7800X3D is the previous 8-core X3D. A 16-core X3D chip is a different model.

Flip checklist for a Ryzen 7 9800X3D
A flip is a real buy price, minus fees and shipping, minus a real sell price. This page does not have those two prices, so it does not print a margin. Confirm Zen 5 8-core before you buy something to resell. Quote is only for an item you already own, and only when a buyback source has published a price.
- Match the spec on the device or the packaging, not only in the title.
- Subtract the fee notes above and shipping before you treat a gap as money.
- Local pickup can skip shipping. Meet in public and confirm it works.
- A number in a video is that creator's example. Search live listings.
