Platform, power and price

The Core i9-10900K uses the LGA1200 socket and the Ryzen 5 5600X uses AM4, so they need different motherboards, and often different memory. When you compare prices, count the board as well as the chip.

Rated power is 125 W for the first and 65 W for the second. That difference changes the cooler you need, and it shows up in heat and noise.

At launch the Core i9-10900K cost $488 and the Ryzen 5 5600X $299, which gives 11.9 and 19.4 points of gaming performance per $100. Today's prices will differ.

Which graphics cards each one can feed, and which to buy

At 1080p the Core i9-10900K can feed a card up to the GeForce RTX 4070 Super before it holds the card back by more than 10 percent. The Ryzen 5 5600X reaches the GeForce RTX 4070 Super. Both chips are in the same range for graphics card pairing.

Choose the Core i9-10900K if you want the faster gaming chip and the same or more cores. Choose the Ryzen 5 5600X if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
