A CPU is an essential part of every laptop or PC. It processes the information within the computer. If your CPU is older it may not have sufficient resources to function efficiently with today's software.

Most modern Operating systems update frequently and evolve over time. In addition, modern media formats expect modern hardware. Older components that were fast can stutter and fail to meet your expectations.

Every computer has one or more cores. A two core computer can handle one task and has another free for system or antivirus tasks for example. A 4 core computer could handle two more demanding tasks before slowing down.

Each core operates at a certain speed. Typically performance cores can boost to higher clock speeds to get high value work done quickly. Generally, higher clock speeds equate to getting more work done in less time.

A Cache is a little bit of very fast memory very close to the CPU. It's like having a notebook on your desk rather than looking through a large book in another room. Larger Cache memory can help keep information close to the CPU.

Some core i5 models have Performance cores and extra Efficient cores to handle less demanding tasks.

I'll first consider Intel's current lineup of processors. Intel CPUs are very efficient and reliable.

The Celeron models are designed for basic mobile applications. They give good battery life for laptops but cannot handle demanding tasks.

Core i3 models are entry models for all round useage. They are ideal for basic use such as word processing and small spreadsheets. Core i5 models have higher clock speeds, more cores and a larger cache.

They are ideal for more demanding business use and entry level gaming.

Core i7 models are designed to run all tasks quickly and without fuss. They are excellent for the most demanding of tasks. Core i9 models are designed for those who want to make the most of their time.

Core Ultra models are both energy efficient and fast. The first models will be laptop parts. They have integrated hardware for processing AI models. At the moment it's probably better to match your cpu with an efficient discrete Graphics card such as an Intel A770 or GeForce 3060 and above.

Don't skimp on cooling. Look for a two fan Air cooler or liquid cooler. A 10 degree centigrade reduction in CPU temperature will double it's life.

You can upgrade your CPU if you have a PC. Laptop CPUs are soldered onto the motherboard. Call in or send your computer to us and we can recommend a faster CPU that is compatible with your current hardware.
