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 24 listings we observed for this game in the last 30 days, we filtered out 16 of 24 (~67%) for quality reasons. The remaining 8 are what we'd actually surface.
- 5 shipped from a region we exclude
- 4 priced above the curated ceiling
- 3 matched a bootleg / out-of-scope keyword
- 3 seller had too few feedback ratings
- 1 priced below our floor (too good to be true)
What the feed excludes
An eBay search for Radeon RX 6400 4GB 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 84 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 Radeon RX 6400 4GB because they are: that's the noise.

RX 6400: buyer & reseller spec sheet
Exact SKU identity. The Radeon RX 6400 is a 4GB GDDR6 card. Sellers write "RX6400" with no space, so this feed accepts both spellings. Its neighbour, the RX 6500 XT, is a different and faster card with a similar-looking number, and the workstation Radeon Pro W6400 is a different product again. Confirm the model and memory from the card's sticker or a GPU-Z screenshot rather than the title.
Variants & value impact. Many RX 6400 listings are low-profile boards sold for small cases, and some are OEM pulls from prebuilt desktops that ship without the retail box. Board partners differ in cooler, size and bracket, not in the headline model. Asking prices vary by partner, by retail versus OEM, and by whether a seller offers a warranty. Confirm the bracket height against your case.
Listing traps.
- Whole PCs naming the card. Workstation and gaming desktops list the GPU in the title at several times the price of a card. They are excluded here.
- Replacement fans and parts. Cooling fans for specific RX 6400 models carry the exact model name and sit beside real cards in search; they are excluded.
If you are weighing a step up, see the RX 6500 XT.
Buying a used graphics card: what to check
These checks apply to every card on our graphics-card pages. The item notes above cover what is specific to this model.
Used
- Ask for a screenshot of a monitoring tool (such as GPU-Z) showing the exact model and memory size, plus a stress test or benchmark run with temperatures visible.
- Ask whether the card was used for mining. Mining wear is mostly fans and thermal pads, which are fixable, but it should be disclosed and priced in.
- Check the photos for bent fins, missing screws, broken fan blades and damaged power connectors.
- Confirm whether the manufacturer warranty transfers. It varies by brand and is tied to the serial number.
Refurbished
- Find out who refurbished it (the manufacturer or a third party) and how long the warranty is.
- Ask what was replaced. A repaste and new pads is routine; a replaced core or memory is not.
New
- Check that the box is factory sealed and the serial on the box matches the card, so warranty registration works.
- Very low prices on "new" cards from new seller accounts are the most common scam on this category.
