Intel Core Ultra 9 285 desktop processor

The Intel Core Ultra 9 285 is a 24-core desktop CPU built for the FCLGA1851 socket. It runs at a base frequency of 4.6 GHz and can reach a maximum turbo frequency of 5.6 GHz. The processor includes 40 MB of L2 cache and 36 MB of L3 cache. Its thermal design power is rated at 65 watts.

Suited for multi-threaded workloads

This processor suits users who need high core counts for rendering, compilation or virtualization while keeping power draw moderate. The 65 watt TDP helps with thermal management in compact or quiet systems. Buyers requiring integrated graphics or higher single-thread boost clocks should evaluate alternative models.

Sustained load behaviour at 65 watt envelope

Under continuous multi-core load the chip operates within its 65 watt thermal design power, so clock speeds will settle below the 5.6 GHz maximum turbo. The large 40 MB L2 and 36 MB L3 caches help maintain throughput by reducing memory latency during long tasks. Cooling solutions rated for at least 65 watts are needed to sustain performance without throttling.

Questions about this item

What motherboard socket is required for the Core Ultra 9 285?

The processor uses the FCLGA1851 socket, so the motherboard must provide that exact socket.

Can the Core Ultra 9 285 run with a 65 watt cooler that I already own?

Yes, the thermal design power is 65 watts, so a cooler rated for at least that TDP will handle the processor.

How can I verify the Core Ultra 9 285 is reaching its 5.6 GHz turbo after installation?

Run a CPU monitoring tool under load and confirm the clock speed hits 5.6 GHz on active cores.
