The CPU (Central Processing Unit) is like your laptop’s brain. It handles almost everything you do — from opening apps to streaming Netflix. The faster and smarter the brain, the better your experience. If your laptop feels slow, the CPU is often part of the problem.
Think of CPU cores like workers in a kitchen. One person can make a sandwich, but three people can prep, cook, and clean at the same time. More cores mean your laptop can do more at once — especially when running multiple programs.
This tells you how fast each core runs. But don’t rely on GHz alone — it’s like comparing cars just by engine size. A newer chip running at 2.5 GHz can outperform an older 3.0 GHz chip because it’s more efficient and smarter under the hood.
One of the most important (and overlooked) factors. A newer generation means better performance, longer battery life, and less heat. For example:
Always check the generation — not just the model name.
Both are great in 2024. Intel chips are common and often better for battery life. AMD Ryzen chips tend to offer more performance for the price. Neither is "better" — it depends on the specific chip and generation.
You’re comparing two laptops:
Option A sounds better because it says “i7,” but it’s using a chip from 2020. Option B has a newer chip that’s faster, uses less battery, and runs cooler — despite being an “i3.”
Verdict: Option B wins for everyday users. Newer tech outperforms old labels.
The same goes for AMD:
The Ryzen 5 is newer and often faster for practical use — especially for school, office work, and video calls.
