Hi, 

I am seeking some advise in choosing between two different workstation setups.
I'd like your opinions on the two setups below.

At my workplace we already have a few years old Lenovo Workstation equipped with the following:
- Intel Xeon W-2133 CPU @ 3.6 GHz (3.9GHz clock speed), 6 cores, 12 threads
- 128 GB RAM DDR4
- NVIDIA Quadro P5000
- SSD Harddrive

But I'm asked if the following Lenovo Laptop would be a better choice:
- Intel Core i7-11800H CPU @ 2.3 GHz (4.6GHz clock speed), 8 cores, 16 threads
- 128 GB RAM DDR4
- NVIDIA T1200
- SSD Harddrive

Hi Kenneth,

 

In order to achieve good overall performance, it is imperative to have the correct balance of processors, memory, and disk I/O. The CPU speed is an obvious factor of performance. However, the other two factors—memory and disk I/O—are not always so obvious. To help you on your performance considerations you can review the section of Performance Guide on Ansys documentation. This section discusses the importance of each major hardware component for achieving optimal performance.

@Giorgos, thank you for the reference. However the information is much to general for me and doesnt really provide enough ground for me to choose between different hardware setups. E.g. will clock speed of the CPU be the factor to compare for performance comparison or do I need to compare nominal speed ? (in my example above, depending on which number to compare, both setups may win). 
And regardign GPU, what is extually important ? Again, both setups may win depending on which parameter we are looking at.
