For many generations of new Intel platforms for entry-level workstations and mobile workstations has been stuck at 32 GB. With the release of the Skylake platform, these workstations now deliver 64 GB of memory capacity.
My old workstation had been puffing along with 8 GB of memory. Fortunately, I was able to increase that. No matter what kind of CAD, 3D modeling, or design work you do, you will be doing it better when your workstation can stretch it's legs with 16 GB of memory.
The great news with Skylake workstations, mobile as well as desktop, is increasing the support from 32 GB to 64 GB of memory. Not everyone needs to break the 32 GB barrier for design and CAD work. But the extra head-room allows you to expand memory capacity as you need it.
Needing more than 32 GB of memory can arise, for example, if you add simulations to your engineering work-flow. There are many excellent simulation and analysis applications available. Many are integrated into CAD applications like SolidWorks, CATIA, PTC Creo and others. As vendors make simulation more accessible to non-simulation experts among their engineering customers, the demand for higher performance workstations – and more memory – increases, too.
