  • 125 W TDP defines cooling and power-supply requirements
  • Core Ultra 7 series targets performance desktop segments

Intel Core Ultra 7 20-Core Processor

This Intel Core Ultra 7 processor delivers 20 cores with a 3.9 GHz clock speed for high-performance desktop computing. It uses the LGA1851 socket and carries a 125 W thermal design power rating. The BX80768265K model belongs to the Intel Core Ultra Processors Series 2 lineup.

LGA1851 Socket and 125 W Power Envelope

Installation requires a motherboard equipped with the LGA1851 socket and a cooling solution rated for at least 125 W of heat dissipation. The processor draws its power from the board’s CPU power connectors, freeing the builder from sourcing a separate power adapter. Compatible memory and chipset support are determined by the chosen motherboard.

Suited for Multi-Threaded Workloads

The 20-core design suits content creators, developers and multitaskers who need parallel processing capacity. Builders targeting lower power envelopes or smaller form factors may find the 125 W thermal output challenging to cool in compact cases. Buyers seeking integrated graphics or different core counts should evaluate other models in the range.

Questions about this item

When does the 125 W power limit throttle the 20 cores under sustained load?

The processor is rated at a 125 W base power; sustained workloads that exceed this limit will trigger thermal throttling to stay within the rated envelope.

How much heat and fan noise should I expect from a 125 W chip running all day?

A 125 W TDP means the cooler must dissipate that much heat continuously; noise depends entirely on the cooler you choose and its fan curve.

Which motherboard and cooler do I need for the LGA1851 socket?

You need a motherboard with an LGA1851 socket and a CPU cooler rated for at least 125 W TDP with the correct mounting hardware.
