How much is a used AMD FX-4100 worth?

A used AMD FX-4100 is currently worth about $11.67, based on verified eBay sold listings through August 29, 2026. That figure tracks completed sales, not asking prices, so it reflects what buyers actually paid. The 30-day average is $11.91 and the 90-day average is $10.52.

How is the used AMD FX-4100 price calculated?

It comes from completed eBay sold listings for this exact component type — prices buyers actually paid, not asking prices. Sold listings are collected on a rolling schedule, matched to the component type with a product-class filter so similarly-named but different hardware is excluded, outlying sales are discarded rather than averaged in, and the published value is smoothed across observations so one unusual week cannot move it. This page is built from 8 dated observations.

Is the AMD FX-4100 going up or down in price?

It is up 42.0% over the last 30 days, from $8.22. Used hardware prices move with supply from upgrades and with each new product generation, so a part can drift for months and then move sharply when a replacement launches.

What is a fair price to pay for a used AMD FX-4100?

Anything up to about $11.00 is a normal market price from a seller who tested the part and offers returns; around $9.00 is a good buy. Its recorded range is $8.22 to $12.81 across 8 tracked price points. Pay below that band only if the part is untested, has no return option, or is missing accessories.

How much can I sell a used AMD FX-4100 for?

Listing it privately around $9.00 is realistic if you are willing to photograph it, answer questions, ship it and absorb the occasional return. Selling it outright to a shop, or inside a whole machine, lands nearer $7.00, because the buyer takes on the testing, the warranty and the time. Neither figure is wrong — they price different amounts of work.

If you are buying a used AMD FX-4100

Anything up to about $11.00 is a normal market price from a seller who tested the part and will take it back. Around $9.00 is a good buy. Below that, work out why: untested, no returns, cosmetic damage, or missing accessories are all legitimate reasons for a discount — and all reasons the price should be lower. A price far under the range above, from a seller who won’t answer questions, is the oldest bait there is.

If you are selling one

Listing privately around $9.00 is realistic if you are willing to photograph it, answer questions, ship it, and absorb the occasional return. Selling it outright — to a shop, or as part of a whole machine — lands nearer $7.00, because the buyer is taking on the testing, the warranty and the time. Neither number is wrong; they price different amounts of work.
