old desktop PC 4770 Vs new lenovo i7

[rangor gubbins]

I've got an old desktop PC with an i7-4770K CPU @ 3.50GHz (i don't bother overclocking it these days). And my work laptop which is a 12 month old lenovo something or other, with an i7 CPU (can't remember which one off the top of my head). I've noticed that when it comes to CPU intensive tasks, e.g. some simple image analysis or statistical analysis, my old desktop PC is usually faster than the laptop. On both systems the same process maxes out the CPU (and does not use the GPU), but the old one is usually faster or at least no slower. Why is my >10 yr old CPU be beating a 1 year old CPU of the same class? Or to put it another way, why is the laptop so crap when it comes to CPU intensive tasks?

Get the exact specs of the laptop and we can check some stuff.

Would be a good idea to run a benchmark like Cinebench too, to assess if the laptop is themal throttling.

The laptop has an i7-1255U, 12M cache, up to 4.7 ghz
I have no admin rights so can't install any benchmark software that would need them

It's plugged in.
I'm wondering if there's a setting somewhere that's limiting the cpu, or as mentioned before it's being thermo throttled. I've put the laptop on a mesh now so that it has airflow underneath.
It's a Lenovo thinkbook 15 G4 IAP. I definitely would not call it snappy. It's also slow to navigate in file explorer, slow to open files, but maybe that's due to network issues/setup.
