Buying guide: Processors (CPUs)

Browse server processors for replacement and upgrade projects. Compare core count, clock speed, processor family and thermal design power where provided.

Confirm the socket, chipset, BIOS support and cooling requirements of your server. Dual-processor systems can require matching CPU models and additional heatsinks.

Hardware supplied by KahnServers includes a 90-day warranty. Check current availability and the individual product specification before ordering.

Start with the platform and installed processor

Record the exact server model and generation, current CPU model and required processor quantity. A shared socket does not establish support for every processor family or revision. Check the manufacturer's processor support list and any BIOS requirements before selecting a replacement or upgrade.

For a second processor, confirm the supported pairing and the hardware needed to complete the installation. This can include a separate heatsink, fans or other model-specific parts. Browse server cooling and heatsinks against the proposed CPU and chassis rather than choosing only by physical fit.

Compare CPUs against the application

Consider the balance of core count, clock speed, memory support and any per-core software licensing costs for your workload. Use our server CPU buying guide and processor compatibility guide to prepare the exact platform, existing specification and planned change before ordering.
