Gaming index (Ryzen 7 9800X3D = 100) against the processors closest to it.
The Core i3-7100 scores 22 on our gaming index, where the Ryzen 7 9800X3D is 100. That puts it #155 of 238 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 2 cores and 4 threads, boosting to 3.9 GHz. With 2 cores, the newest games will stutter or limit your frame rate, because they are built for six or more.
The Core i3-7100 uses the LGA1151 socket, so it fits motherboards with that socket. The fastest chips we track on the same socket are Core i9-9900K and Core i7-9700K, which would be a drop-in upgrade without changing the motherboard.
It is rated at 51 W. That is low enough for small cases and quiet builds.
At 1080p, where the processor matters most, the Core i3-7100 can feed a card up to the Arc A580 before it starts to hold the card back by more than 10 percent. At 1440p the limit moves to the Radeon RX 7600. At 4K, where the card does most of the work, it can keep up with the Radeon RX 9060 XT 16GB. The full list of graphics cards for the Core i3-7100 has the options for each resolution.
The Core i3-7100 is old or low power. Expect new games to run poorly, and look at an upgrade before you buy a new graphics card.
