AMD FX-Series FX-4100 4-core Socket AM3+
The unlocked multiplier on this 32nm Zambezi chip allows for straightforward overclocking on the aging AM3+ socket, with a 3.8GHz boost clock and 8MB of L3 cache. Its 95W TDP and included boxed cooler keep entry costs low for a basic quad-core build, though single-threaded performance is notably weak at a 2534 PassMark score. This processor is best for ultra-budget system builders who only need to run legacy applications or handle light office productivity tasks.

Performance
The single-thread score of 2531 puts this chip in the 71st percentile, which honestly surprised us. That's not terrible for a 32nm part from over a decade ago. Multi-thread lands at 62nd percentile, so it's about average for its class. The 3.8GHz boost clock helps in bursty workloads, and the unlocked multiplier means you can push it further if you've got decent cooling. But don't expect miracles in synthetic benchmarks, this chip gets smoked by modern budget CPUs. Real-world DX11 gaming is where it shines, especially paired with older Radeon cards.

vs Competition
Against the Intel Core 2 Duo E8500, the FX-4100 wins on core count and multi-threaded workloads, but the E8500 actually has better single-thread performance in some tests. The AMD A10-5800K is the more interesting comparison, it's got integrated graphics and similar architecture, but the FX-4100's dedicated CPU focus gives it an edge in raw compute. The Dell Xeon E5-2637 V2 is in a different league entirely, but it's also a server chip that won't fit in your AM3+ board. For pure budget desktop use, the FX-4100 holds its own against these older competitors.

Precio
Value & Pricing
Here's the thing: prices are all over the place. We're seeing listings from USD 23 to USD 390, which is frankly absurd for this chip. The sweet spot is clearly the low end. At USD 23 from the US listings, this is a steal for a budget build or a cheap upgrade to keep an old AM3+ system alive. At USD 390, you're getting robbed. Buy the cheapest one you can find and don't look back.

Overview
The AMD FX-4100 is a budget quad-core from 2011 that still has a pulse if you know what you're getting into. It's not going to win any benchmark shootouts, but for the right price and the right use case, it's a surprisingly capable little chip. The one thing to know: this is a value play for budget builds and retro gaming rigs, not a modern productivity workhorse.
Common Questions
Q: Can I overclock the FX-4100?
Yes, and you should. The multiplier is unlocked, so you can push it past 4GHz with a decent cooler. Just don't expect modern performance, it's still a 2011 chip.
Q: Is this good for gaming in 2024?
For older DX11 titles and esports games at low settings, sure. For modern AAA games, no. This is a retro and budget gaming chip, not a current-gen performer.
Q: What motherboard do I need?
You need an AM3+ socket board. Make sure your board supports the 95W TDP, and check for a BIOS update if you're pairing it with an older board.
Who Should Skip This
If you're building a modern system for productivity, content creation, or current-gen gaming, this isn't it. Go grab a used Ryzen 3 or even a newer Intel i3 instead. The FX-4100 is for budget tinkerers and retro enthusiasts only.
Verdict
If you need a cheap quad-core to breathe life into an old AM3+ system or build a budget retro gaming rig, the FX-4100 is a solid pick at the right price. Just don't pay more than USD 30-40 for it, and be careful with those pins. It's not a modern performer, but it's honest about what it is.
