Intel i9 13th Gen has 24 cores. Do I still need a workstation with zeon processors? What is the difference??

Few questions: latest workstation laptops v/s desktops with same configuration..does it really matter? i9 Gen 13 has 24 cores. do I still need to focus on 2 zeon processors with expensive mother boards? 8 * 8 ddr5 ram or 16 *4 ddr 5 ram on the workstation.. how much difference does it make?
i am doing eigen frequency analysis and it takes me 2 hours on a latest zeon workstation with 64 gb ram ddr4. Wanted to do these iterations in 30 to 45 minutes to meet some deadlines. Ist that possible??
high processing power v/s high ram (say 64gb or more..how to decide.
Budget is not a constraint.
thanks in advance...

Dear Sandy,
I don't think it is very different between i-core and xeon-core. The number of cores and speeds are the most important. The differences between i-core and xeon-core are that i-cores are not designed for last super long and staple. Also, the workstations have special ram. But, I think your PC is good enough for COMSOL. I am using Dell workstation dual gold xeon and 64GB Ram. It is little faster than i5 (6 year old) with 32 GB. To speed up calculation, you should consider symetrial geometry then reduce the size to reduce the number of DOF to speed up. It is much better than investing on computer.

With regards to the Xeon Gold processor, these have six, or eight (in the newer generation) memory channels, and should only be used in at least dual-CPU configurations. You should get a speed upgrade if you upgrade such a system so that all memory channels are filled.

It's worth looking into why your calculation takes a long time. If the calculation is going out of core there may be a big payoff for adding more memory. Or looking very carefully at meshing and symmetries to see if you can reduce the problem size.
