Question core i-5 series H vs core i-7 series U

[xilin_0]

Hi,
My previous thread discussed a generation of CPUs. Now, I would like to compare two specific CPU models and make several inquiries about each. Here is the comparison between these two CPU models: Intel i5-13420H vs. Intel i7-1255U
https://www.cpubenchmark.net/compare/5434vs4794/Intel-i5-13420H-vs-Intel-i7-1255U
I should mention that the H series is generally stronger than the U series. However, the benchmark scores are also higher, and the TDP of the Core i5 is greater. One point of interest for me is that the base clock speed of the Core i7 is 1.7 GHz (I hope I am using the correct term). Some applications require a minimum frequency of 2.0 GHz, and I am unsure if those applications would run effectively or need turbo speed or manual overclocking. I apologize if I am mistaken.
To get to the point, my question is: even though the Core i7 model has slightly more cores and the same number of threads, which one should I pursue? My purpose is programming, which can be efficiently done with either CPU, but I am particularly interested in networking simulations that require more RAM. From my research, both models can be upgraded to sufficient RAM for my needs.
Another point is that the Core i5 has 8 cores, with 4 dedicated to performance and the other 4 for efficiency. However, I am unsure about their specific functionalities and when they play their respective roles(rest 4 cores) 😀
Also core i-5 has the
Intel® Virtualization Technology (VT-x) ‡
and
Intel® Virtualization Technology for Directed I/O (VT-d)
NOTE: My current CPU's clock speed(CPU released 2011) is 2.0 GHz 🙄😏 1255U is 1.7 GHz
I know which parameters must be considered in the laptop's CPU but should I go with a core i-7 laptop or a core i-5?


thanks

Default clock speeds do not mean much.
All processors will increase clock speeds when the load demands it.
The cpu comparison is valid, and the 13420H is the stronger.
When all of the threads are fully loaded, the 18485 rating is still stronger than the 13591 rating of the 1255U.

In my comparison, I couldn't find any significant advantages of the Core i7 over the Core i5."
I wonder why one should go for core i-7 with weaker processor while core i-5 provides stronger and better performance

I3/I5/I7/I9 used to indicate the number of cores and with or without hyperthreading.
Not so today.
I5/I7... is now a general capability indicator.
Also, we are looking at 12th/13th/14th gen processors.
Each newer gen will have some added advantage. Price/performanc/power...
The IPC( instructions per clock) may get better.
