Gaming index (Ryzen 7 9800X3D = 100) against the processors closest to it.
The Core i3-10300 scores 36 on our gaming index, where the Ryzen 7 9800X3D is 100. That puts it #116 of 239 processors we track, in D tier. It is an older or entry level chip. Fine for light games and mid-range cards, but a fast graphics card will often wait on it.
It has 4 cores and 8 threads, boosting to 4.4 GHz. With 4 cores, the newest games will stutter or limit your frame rate, because they are built for six or more.
The Core i3-10300 uses the LGA1200 socket, so it fits motherboards with that socket. The fastest chips we track on the same socket are Core i9-11900K and Core i9-10900K, which would be a drop-in upgrade without changing the motherboard.
It is rated at 65 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 Core i3-10300 can feed a card up to the Arc B580 before it starts to hold the card back by more than 10 percent. At 1440p the limit moves to the Radeon RX 9060 XT 16GB. At 4K, where the card does most of the work, it can keep up with the GeForce RTX 4080 Super. The full list of graphics cards for the Core i3-10300 has the options for each resolution.
The Core i3-10300 is fine for older games, light titles and a modest card, but it will hold back a newer mid-range card.
