FAQ

Frequently asked questions

What is the PGA478 socket?

It is the mechanical and electrical interface between a processor and motherboard. This page groups CPUs recorded by CPULoom for the PGA478 platform.

Will every PGA478 CPU work in any motherboard with that socket?

Not necessarily. Chipset, BIOS revision, processor-generation support and board power limits can differ, so check the motherboard manufacturer’s official CPU support list.

What is the best CPU for PGA478?

The performance ranking highlights the highest stored CPU Mark results, but the best choice also depends on workload, budget, motherboard capability, cooling and power use.

Can I change CPU socket without replacing the motherboard?

Usually not. The socket is part of the motherboard, so moving to another socket requires a compatible board and may also require different memory or cooling hardware.

This summary is calculated from processor records linked to the category. Performance results are broad comparison indicators and can vary with system, power and cooling. Latest data update: 2026-10-20
