Core X i7-9800X octa-core processor

The Intel Core i7-9800X is an eight-core desktop processor built on a 14 nanometer process and designed for the LGA 2066 socket. It ships without a cooling device so the builder must supply a compatible solution. The processor targets workstations and enthusiasts who need strong multi-threaded throughput.

Sustained load behaviour

With a 165 W thermal design power the chip maintains its 3.80 GHz base frequency across all cores during extended workloads. The 16.50 MB L3 cache and 8 MB L2 cache keep data close to the execution units, reducing stall cycles when the cores run continuously at high utilisation.

Build and mounting implications

The LGA 2066 package uses a large land-grid array that requires a socket-specific retention mechanism and a cooler rated for the 165 W envelope. Because no cooler is included, the builder must plan for adequate airflow and mounting pressure to keep temperatures stable under full load.

Questions about this item

How much heat does the 165 W TDP of the Core i7-9800X produce during all-day workloads?

The processor is rated at 165 watts, so sustained loads will push that much heat into your cooling solution; plan for a high-capacity air or liquid cooler rated at or above 165 W.

What motherboard socket must I already have for the i7-9800X to install?

The CPU uses the LGA-2066 socket, also referred to as Socket R4, so the board must provide that exact socket.

Will my existing LGA-2066 cooler fit the 14 nm Skylake-X die of the 9800X?

Yes, the i7-9800X fits the standard LGA-2066 mounting pattern, so any cooler validated for that socket will physically attach.
