Celeron Socket 478/N Computer Processor

Find an Intel Celeron Processor for Socket 478

Intel made a number of Celeron microprocessors that fit its Socket 478 standard. If you have a motherboard that has Socket 478, then you'll need to get a processor that fits it for any CPU repairs or upgrades. You can find a selection of these processors available to meet your needs.

Socket 478 was Intel's specification for motherboard CPU sockets that fit the Pentium 4 generation of processors. The technical designations of these sockets were mPGA478 and mPGA478B, but they are commonly referred to by the number of pin contacts they have, which is 478.

There are a few different Intel CPUs in their Celeron product line that are compatible with Socket 478:

• Williamette Celeron processors: The earliest to fit this socket, they were based on the Williamette version of the Pentium 4 and had clock speeds of 1.7GHz and 1.8GHz.
• Northwood Celeron processors: The Northwood generation of mobile processors had clock speeds ranging from 1.8GHz to 2.8GHz.
• Celeron D processors: Based on the Prescott dual-core Pentium D, this is the last generation designed to fit Socket 478. They had clock speeds from 2.13GHz to 3.33GHz.

A microprocessor's performance depends on a number of different features, and clock speed is just one of them. A CPU's clock speed determines the speed at which it executes each individual instruction. It can be compared to the RPM of a car's engine, which measures how fast the vehicle is running. A CPU's performance is affected by other factors, like the efficiency of its microarchitecture, how many physical cores it has, and whether it has advanced features like hyper-threading. The simplest way to gauge a processor's performance is to check its benchmark scores.

The exact procedure will depend on the motherboard and CPU cooler you're using for the installation. You should refer to your motherboard and processor manufacturer's instructions before beginning. These are the basic steps you'll need to complete:

• Step 1: Lift the socket's arm to disengage its locking mechanism. Holding the CPU by its edges, orient it correctly over the socket, and carefully drop it into place on top of the connector pads. Don't apply pressure.
• Step 2: Once the CPU is seated flush, lower the arm, and lock it into place.
• Step 3: Install the heatsink on top of the CPU according to the instructions that came with it. If it comes with a cooling fan, locate the correct power connector nearby on the motherboard and plug it in.
