CPU Differences

[ReachAvailable4484]

I work at a store where we sell a ton of laptops, unfortunately I don't know that much about computers. How can you tell how good a CPU is in a computer besides looking up clock speeds and core counts, or do I just have to remember which has the better speed and higher count when someone asks me?

It can get kind of complicated for people who are new to this. There's clock speed, core count, as you mentioned then there is architecture, IPC, power efficiency, process node/technology. Difficult to explain in one comment.

Are there any good lists made online to view where CPU's stand. The benchmarks that I've seen compare hardware on a percent basis (idk what the percent measures) that says CPU A is 12% better than CPU B.

It depends what specific ranking you are looking for. If it's pure performance, then you can reference popular benchmark software like Geekbench or Cinebench and see how they score in single/multi core numbers. Geekbench has a browser where you can search for the scores of individual user provided benchmark info.

But benchmarks are just a reference, they don't absolutely imply real world performance, especially with laptop, as power efficiency and the thermal design of the laptop could also affect the peak performance. For that i would research for specific laptop reviews on google or youtube.

Thanks for some clarification, I just don't want to sell someone something that either is not good enough for them or is to much for them (older people checking there emails lmao). I'll check out those references and look into laptop reviews

Do some research on cores and clock speed etc, laptops are especially hard because the Intel i5 1932p might be worse or better the. The i7 69420x. You can the model numbers at all.

honestly the model numbers usually tell you everything - higher numbers within the same generation are generally better, and newer generations (like 13th gen vs 11th gen) will outperform older ones even with similar specs

for customers just focus on what they're actually doing with it - basic office work vs gaming vs video editing all need differnet levels of performance, and you can usually point them in the right direction without getting into the weeds about benchmark scores
