On our gaming index the AMD FX-4100 scores 11 and the AMD FX-6100 scores 10, about 10% faster for gaming. That gap is small and mostly shows up at 1080p with a very fast graphics card.
The AMD FX-4100 has 4 cores and 4 threads, and the AMD FX-6100 has 6 cores and 6 threads. The extra cores of the AMD FX-6100 help with video editing, streaming while you play and heavy multitasking more than with the game itself. Boost clocks are 3.8 GHz and 3.9 GHz.
Both chips use the AM3+ socket, so they fit the same motherboards. You can swap one for the other without changing the board.
Rated power is 95 W for the first and 95 W for the second. That is close enough that cooling needs will be similar.
At launch the AMD FX-4100 cost $112 and the AMD FX-6100 $165, which gives 9.8 and 6.1 points of gaming performance per $100. Today's prices will differ.
At 1080p the AMD FX-4100 can feed a card up to the GeForce GTX 1650 Super before it holds the card back by more than 10 percent. The AMD FX-6100 reaches the Arc A380. If you plan to buy a fast graphics card, that gap is the real difference between these two.
Choose the AMD FX-4100 if you want the faster gaming chip. Choose the AMD FX-6100 if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
The AMD FX-4100 is about 10% faster than the AMD FX-6100 in our estimate.
If your graphics card is already the limit in your games, a faster processor adds little. Use the bottleneck calculator to check your own pairing.
