AMD FD6100WMGUSBX

The AMD FX-6100 is a six-core relic from 2011 with a 31.4 overall score in our database. Single-thread performance is its biggest weakness, landing in the 27th percentile. Only worth buying if you find it dirt cheap and already have an AM3+ board lying around.

The FX-6100 runs at 3.3GHz base and boosts to 3.9GHz. Six cores, six threads, 8MB of L3 cache. PassMark scores tell the real story: 3710 multi and 1313 single. That single-core number is rough. Most modern budget chips triple that without breaking a sweat. Multi-thread is better thanks to those six cores, but it's still middle-of-the-pack at best in our rankings. The 95W TDP means it pulls decent power for what you get. Efficiency lands in the 34th percentile, which is mediocre. If you're running older games or light server tasks, it'll chug along fine. Just don't expect it to keep up with anything made in the last decade.

Against the competition, the FX-6100 doesn't hold up well. The Intel Core Ultra 5 225 is in a completely different universe, modern architecture, way better efficiency, and single-thread performance that embarrasses this chip. The Dell Xeon E5-2637 V2 is also old but at least brings server-grade reliability. Even the Phenom II X6, another ancient AMD chip, trades blows with the FX-6100 in some workloads. The be quiet! Ryzen 3 Dark Rock Pro 5 isn't even a CPU, it's a cooler, which tells you how thin the competition data is here. Bottom line: if you're buying new, any modern budget chip beats this. If you're buying used, you can probably find something better for the same price.

Pricing is all over the place depending on where you look. US listings show it around $64, but European sellers want EUR 139 to EUR 153. That's a big spread. If you're in Europe, the DE listing at EUR 139 is the best deal we found, but honestly, even that feels steep for a chip this old. At $64 it's a maybe for a retro build or a cheap home server. At EUR 153 it's a hard pass. You can get a modern entry-level CPU that runs circles around this thing for similar money in most markets.

The AMD FX-6100 is a six-core chip from a different era. Socket AM3+, 95W TDP, and a 3.9GHz boost clock. It was a budget workhorse back in the day, and some people still swear by it for cheap builds. But our database puts this thing at 31.4 out of 100 overall. That's not a typo.

Here's the thing. It has six cores, which sounds great on paper. But single-thread performance sits in the 27th percentile. Multi-thread is 32nd. For modern gaming or any serious productivity work, this chip struggles. It's a 2011 processor in a 2025 world.

Skip this if you need anything resembling modern performance. If you're building a gaming PC, a budget workstation, or anything that runs current software, look elsewhere. The single-thread performance will frustrate you daily. Also skip it if you don't already own an AM3+ board, since buying one just for this chip makes no sense. And if you're in Europe seeing those EUR 139+ prices, run. That's robbery for a 14-year-old processor.

The FX-6100 is for a very specific buyer. Someone building a dirt-cheap AM3+ system with parts they already own. Someone who needs six cores for light server work and doesn't care about single-thread speed. Someone who found one for $30 at a garage sale. If that's you, fine, it'll work. For everyone else, this chip is a relic. It was decent value in 2011. It's not 2011 anymore.
