Are the Number of Cores/Threads and Core Clock the two only things that matter when talking about how strong a CPU?

If so, does it mean that i5 10400f is faster than i5 11400f? They have the same number of cores/threads but 10400f's clock speed is faster. That's impossible!

The single core performance of the new CPU is up to 30% better than the old one - https://www.notebookcheck.net/Intel-Core-i5-11400-Geekbench-listings-suggest-that-it-is-30-percent-faster-than-its-predecessor-in-single-core-tasks.523294.0.html

its difficult to tell when half the tests on page you got that from are yet to be done - https://www.cpu-monkey.com/en/compare_cpu-intel_core_i5_10400f-1247-vs-intel_core_i5_11400-1870

IPC is more important than clock speed now, they are becoming more efficient - https://www.tomshardware.com/reviews/ipc-cpu-definition,5777.html

You can use core count and clock speed if comparing the same family or generation of processor. You can't with different generations of processors. Though if you need a "close enough" WAG, there's usually a 15% clock-for-clock performance bump between generations, minus a few exceptions.

Ok, thank you guys for the answers. At first, I think it's because of PCI-E 4.0 technology but I don't think it's related.

The thing is I want to upgrade my PC in the next 2 months. And due to the low budget, I really expect this i5 11400f, hope that it's can handle every game at a low price so that I can focus on saving money on GPU instead.

When I see the core clock speed I'm quite disappointed. But I think I should wait a few more days for the benchmark.

11400F should smash through every game without a single problem.
