As applied to the computer world, the term “Workstation” was exploited so mercilessly that over time it lost its essence. Of course, because you do not drive into a narrow framework that falls under the term “Workplace”? Want a small silent computer for the accountant-please, want a two-processor beast for 6 graphics cards-please, both in the understanding of PC manufacturers can be called the word “Workstation”, but this term originated in the world of applications for working with graphics and various scientific software packages. And if the management has set you the task of choosing a “Workstation”, then in order not to spend money twice, be able to distinguish an ordinary office PC from a real workhorse.
1. Really large number of CPU cores
All accurate calculations, whether it’s rendering a movie or calculating molecules, are done on the CPU, and all modern software packages, whether it’s Ansys, Blender, Knime or simple Python frameworks, use multithreading, that is, simultaneously calculate data on several processor cores. Therefore, a typical workstation has 24 or more cores. Prepare for the fact that you will need 48 to 128 physical cores, giving 256 threads in HyperThreading mode.
Keep in mind that as the number of cores on the processor increases, you will have a decrease in the base frequency of each of the cores. Gaming computers easily flaunt frequencies from 3.5 GHz and above, but have 4-8 cores. In multicore processors, it can range 2.1-2.8 GHz, but due to the large volume cache integer operations on such processors are faster, and even though the computer will give the workstation in the speed of loading Windows or in games, the task of rendering a typical gaming PC can get bogged down for weeks, and workstation count the scene in a matter of days or hours.
