Gaming index (Ryzen 7 9800X3D = 100) against the processors closest to it.
The AMD FX-4100 scores 11 on our gaming index, where the Ryzen 7 9800X3D is 100. That puts it #221 of 239 processors we track, in E tier. It is slow by current standards, and recent games will often run well below what the graphics card can do.
It has 4 cores and 4 threads, boosting to 3.8 GHz. With 4 cores, the newest games will stutter or limit your frame rate, because they are built for six or more.
The AMD FX-4100 uses the AM3+ socket, so it fits motherboards with that socket. The fastest chips we track on the same socket are AMD FX-9590 and AMD FX-8350, which would be a drop-in upgrade without changing the motherboard.
It is rated at 95 W. That is easy to cool; a decent tower cooler is enough, and the box cooler works on some models.
At 1080p, where the processor matters most, the AMD FX-4100 can feed a card up to the GeForce GTX 1650 Super before it starts to hold the card back by more than 10 percent. At 1440p the limit moves to the GeForce GTX 1660 Super. At 4K, where the card does most of the work, it can keep up with the GeForce RTX 4050 Laptop.
The AMD FX-4100 is old or low power. Expect new games to run poorly, and look at an upgrade before you buy a new graphics card.
Graphics card performance index it keeps up with at each resolution.
The AMD FX-4100 is a E-tier gaming processor: #221 of 239 in our list, with 4 cores and 4 threads up to 3.8 GHz. At 1080p it can feed a card like the GeForce GTX 1650 Super without a CPU bottleneck above 10%, and at 1440p a GeForce GTX 1660 Super.
At 1080p it can feed a card like the GeForce GTX 1650 Super without a CPU bottleneck above 10%. At 1440p, a card like the GeForce GTX 1660 Super is a reasonable ceiling.
