The Core i7-10700K has 8 cores and 16 threads, and the Core Ultra 7 155H has 16 cores and 22 threads. The extra cores of the Core Ultra 7 155H help with video editing, streaming while you play and heavy multitasking more than with the game itself. Boost clocks are 5.1 GHz and 4.8 GHz.

Platform, power and price

The Core i7-10700K uses the LGA1200 socket and the Core Ultra 7 155H uses BGA, 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 28 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 Core i7-10700K can feed a card up to the Radeon RX 6800 XT before it holds the card back by more than 10 percent. The Core Ultra 7 155H reaches the Radeon RX 6800 XT. Both chips are in the same range for graphics card pairing.

Choose the Core i7-10700K if you want the faster gaming chip. Choose the Core Ultra 7 155H if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
