At the end, only a benchmark can tell.
These are a bit older processors, but they have the advantage of 4
memory channels (instead of 2). Since we know that when all cores are
used, the speed is limited by the memory, it could well be that they are
faster in these cases (and usually, due to
lapw1 benchmarks (autocorrect)

Can you ask your vendor to benchmark the speed, e.g. using the laptop
benchmarks? That is great most accurate method.

Can an X-series processor like i9-10900x or i9-9900x with larger memory
bandwidth (94 GB/s and 85GB/s
vs 50GB/s for i9-11700k and i7-10700k) but slower RAM DDR42933 make faster
calculations.

I'd go for a 8 core processor of the 11. generation like
I9--11900K or I7-11700K
which support already the faster DDR4-3200 RAM.
I'd also configure 64 GB RAM and besides the SSD an additional 2TB disk
(7/24 duty - i.e. made for continous use).

Dear wien2k user,
we are planning to purchase a system for
working on monolayer semiconductors consisting of 30 to 50 atoms in
supercell. We can't afford to purchase a cluster.
can we go for a system with I7-10870h processor Ram 32gb ssd 1tb.
Any suggestions would be
