I have 2 laptops and 1 is older cpu but higher clock rate and another one is more modern cpu but lower clock so which one would generally have a better performance?

first laptop: Celeron 2.16 Ghz while second laptop:Intel I3 1.88 Ghz Both 4 cpu cores.

Depends on what you do when you're on your computer:

More cores, slower clock speed

Pros

  • Applications that support multi-threading will greatly benefit from having a higher number of cores at their disposal
  • Increasing the number of cores in your CPU is a cost-effective way of increasing performance
  • Multi-threading support for applications will continue to improve over time
  • You will be able to run more apps at once without seeing performance drops
  • Great for running multiple virtual machines

Cons

  • Lower single-threaded performance than a higher clock speed processor

Fewer cores, higher clock speed

Pros

  • Better single threaded performance
  • Lower cost option

Cons

  • Fewer cores to split between applications
  • Not as strong multi-threading performance

Ratings on CPUBENCHMARK:

  • Celeron 2.16 Ghz = 951
  • Intel I3 1.88 Ghz = ??? (need model number)

TL:DR

There are other factors that go into this to be compared such as cache, bus speed etc. I would compare the 2 benchmarks on https://www.cpubenchmark.net and see which comes out the victor.

    The second laptop will be much faster, despite its slower clock. It can do more per clock, and most non-trivial programs will take advantage of multiple cores. – davidgo Mar 24 '18 at 8:44
