Platform, power and price

The Ryzen 7 7840HS uses the BGA socket and the Core i9-10900K uses LGA1200, so they need different motherboards, and often different memory. When you compare prices, count the board as well as the chip.

Rated power is 35 W for the first and 125 W for the second. That difference changes the cooler you need, and it shows up in heat and noise.

We do not have launch prices for both chips, so we cannot compare value.

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

At 1080p the Ryzen 7 7840HS can feed a card up to the GeForce RTX 4070 Ti before it holds the card back by more than 10 percent. The Core i9-10900K reaches the GeForce RTX 4070 Super. Both chips are in the same range for graphics card pairing.

Choose the Ryzen 7 7840HS if you want the faster gaming chip. Choose the Core i9-10900K if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
