Ryzen 9 7940HS vs Core i9-11900K

Gaming speed, cores and clocks

The Ryzen 9 7940HS has 8 cores and 16 threads, and the Core i9-11900K has 8 cores and 16 threads. Core counts are the same, so cache size and clock speed decide the difference. Boost clocks are 5.2 GHz and 5.3 GHz.

Platform, power and price

The Ryzen 9 7940HS uses the BGA socket and the Core i9-11900K 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 9 7940HS can feed a card up to the GeForce RTX 4070 Ti before it holds the card back by more than 10 percent. The Core i9-11900K reaches the GeForce RTX 4070 Ti. Both chips are in the same range for graphics card pairing.

Choose the Ryzen 9 7940HS if you want the faster gaming chip and the same or more cores. Choose the Core i9-11900K if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
