Since high performance, high scalability workstations can cost a bit more than traditional desktops or laptops, people should do some comparison shopping first. An entry-level desktop workstation can be both price competitive and still offer many features of traditionally higher priced workstations. So what should you look for when you are comparing hardware features?
Dual Core vs. Quad Core
One thing to consider is that CAD is still mostly a single-threaded application (yeah, there are some places it is not like rendering and FEA and it is slowly creeping into other aspects of CAD), but if you mainly do CAD modeling, max clock speed is the goal. On a desktop workstation, the quad core offers highest frequency (3.2 GHz) vs. the dual core (2.53 GHz). While six cores are not necessary for Solid Edge, you should consider what other applications you will be running, perhaps simultaneously, to determine the total number of cores you will need.
On a mobile workstation, however, both the quad core and dual core processors offer the same frequencies (max turbo), the quad core does so at a much higher price point. The base frequency on the quad core is lower (2.50 GHz).
Higher power graphics and more memory are both are important for CAD when loading complex models and assemblies and of course manipulating them fluidly. It is the workstation where the delineation between these components (memory, OpenGL graphics and CPU speed) and a normal desktop is most noticeable.
A couple folks on the Solid Edge forum pointed out they have gotten some good deals at the Dell Outlet store. These are not brand new systems and the inventory can fluctuate, but if you are on a tight budget this option may be for you. I’d hate to manage a CAD team where every designer has a different model, but for an individual or small shop, it might be worth considering.
Below are some sample configurations to help you in your research. These configurations were provided by Dell so Solid Edge users could have some comparisons during the Solid Edge ST4 Global Launch Event, held June 15-16, 2011, in Huntsville, Alabama.
