How we filter
Every feed has its own filter, tuned by hand for this one part. Before any change goes live, those filters are tested against thousands of real eBay listing titles. Every night, each feed is checked against every other deal page in its category, so a listing for a different part that slips in gets flagged and fixed instead of quietly shown.
Of the 63 listings we observed for this game in the last 30 days, we filtered out 35 of 63 (~56%) for quality reasons. The remaining 28 are what we'd actually surface.
- 17 matched a bootleg / out-of-scope keyword
- 8 priced above the curated ceiling
- 8 seller had too few feedback ratings
- 2 seller positive-feedback percentage too low
What the feed excludes
An eBay search for AMD Ryzen 9 9900X returns far more than the part itself: laptop chips, mining rigs, coolers, empty boxes and whole PCs all mention it in their titles. These are the 50 terms we filter out to keep this feed to the real thing. A listing whose title contains any of them never reaches the feed, the price table or an alert. Many look unrelated to AMD Ryzen 9 9900X because they are: that's the noise.

Ryzen 9 9900X: buyer & reseller spec sheet
Exact SKU identity. The 9900X is a 12-core, 24-thread desktop processor for the AM5 socket. The name nests inside the Ryzen 9 9900X3D, a different chip with stacked cache that usually asks noticeably more. Titles like "9900X3" with the last character cut off appear too. This feed excludes the X3D chip, but if a listing is ambiguous, check the model printed on the chip in the photos and the part number in the listing. Don't rely on the title alone.
Variants & value impact. Retail boxed, "WOF" part-number and OEM tray listings all show up. A tray chip usually ships without a cooler or retail packaging and often asks less. Whether the original box is included explains some of the asking-price spread within Used. Open box listings are counted with New on this page, so read the description to see whether the chip was ever installed.
Listing traps. Whole gaming PCs and prebuilt towers list under this CPU's name because it is the headline part, as do CPU-and-motherboard combos. They are excluded by title wording and by the price ceiling. Listings for the empty retail box alone also appear, and the filter drops them. Ask for sharp photos of both sides of the chip, and confirm your motherboard's BIOS supports it.
Buying a used processor: what to check
These checks apply to every processor on our CPU pages. The item notes above cover what is specific to this model.
Used
- Ask for a clear, close photo of the pins or contact pads, wherever the socket keeps them. Bent pins are the most common failure.
- Confirm the model printed on the heat spreader matches the listing, and ask for a screenshot of the chip identified in the OS or BIOS.
- Ask whether it was overclocked or delidded. Neither is a dealbreaker, but both should be disclosed.
Refurbished
- Find out who tested it and what the return window is.
New
- Check whether it is a boxed retail chip or a tray chip. Tray chips usually ship without a cooler and with a different warranty.
