Is the clock frequency in any case more important than the number of cores for Minecraft's smooth playing?

I would like to get a new laptop on which I, in addition to the daily surfing, Netflix, etc. Also times large Minecraft Modpacks with texture pack and with enough fps can play.

Now it is said that the most important thing for Minecraft is not RAM or graphics card, but the clock frequency, the game uses only one core. A mediocre graphics card and 8 GB of RAM are a prerequisite.

Does that mean that z. B. The

i3-8145U with 2.1 / 3.9 GHz and 2 cores

in contrast to

i7-9700T with 2.0 / 4.1 GHz and 8 cores

virtually no difference in performance, they are equally well suited for Minecraft?

You can't compare younger and older generations.

It's always a bit critical with GHz anyway.

THEORETICALLY one can determine at the GHz which is now more powerful. BUT not only GHz but also the performance per GHz are improved every year, you can't generalize that.

RAM needs Minecraft but definitely synonymous. Besides, MC is not 100% singlecore. From 1.8 e.g. Chunk rendering has been outsourced to other cores

What can be helpful with Minecraft are the cache sizes of the CPU, ie L1, L2 and L3 cache.

These caches are significantly faster than RAM (because they are directly on the CPU and dedicated memory) and prepare data for CPU processing so that the CPU can calculate directly instead of having to process data first.

And since the two processors are very different.
BUT - and there you are not so wrong with your question - the caches are accessed in the clock frequency of the CPU, so that's correct. However, pure cache size is more crucial and important.
