? Old vs New GHz nums for cpus ?

mcenter777

It's been quite a while since I shopped for a computer (laptop) and I'm looking to replace it. But the GHz numbers on the laptops these days are confusing: My old laptop that I bought in 2014 has an intel i-7 4710hq which is rated at 2.50 ghz. But I see laptop cpus now that are in the 11th and 12th gen of i-7 or i-9 but they are 1.10 ghz and other small numbers and the laptops are still pretty highly priced. Does 1.5 ghz with an 11th gen i-9 produce more output than an i-7 4710hq (from 2014)? If so, what's a good way to compare processor speeds when comparing laptops?

Most of the numbers you are looking at are the base clock speeds of these processors, many have another number listed after that in the spec sheet (many of the ones you listed boosting well into the 4ghz or even 5ghz range).

Advancements in architecture, cache, and lithography (the actual size of each transistor in the silicon) have made much more of a difference these days then the ghz. Looking for these differences in these specs can be difficult if you don't know where to look or where to find reputable benchmarks but any of the associates in your local Micro Center are trained on which CPUs perform best based on these benchmarks and specs. They would be able to explain this more in depth with you as well!

Thanks. It seemed like there just had to be some kind of "hidden knowledge" or the like. Your info will help me find it. Or I'll just flip a coin ;) - not really!

Benchmarking websites are good to compare these types of things, such as https://www.cpubenchmark.net/laptop.html or https://www.notebookcheck.net/Mobile-Processors-Benchmark-List.2436.0.html
