Notebooks are built around power consumption constraints that desktop systems are not - that alone could account for the difference. Further, it's likely the desktop you have runs a true dedicated video card and GPU the notebook doesn't have. Since the advent of Windows XP, more and more processing duties have been offloaded to the GPU by Windows. Bottom line: even with similar or higher specifications, the notebook will be slower than a desktop system.
You CAN run SolidWorks well on a mobile system - you need a workstation-class mobile to do it though (i.e., a Dell Precision M6800 or a similarly equipped Alienware 17 to do it. It's not going to run optimally on any consumer-grade Inspiron or XPS system (or any similar system from other manufacturers).
I understand that it should not run similarly as there is a vast difference in optimization and hardware between workstation class and premium mobile.
The reason why I have a problem grasping the performance difference is because I have used non-workstation class laptops and desktops which outperformed my xps 15. That should not be the case.
Still, my issue stands. Why is the ram underclock? I reinstalled CPU-Z twice to make sure its reading it properly and so far its been giving the same frequency of 1066mhz reading. Is this normal?
DDR means double data rate - that is, the actual speed of the RAM is half what's quoted. The RAM runs at 1066 MHz, and the signal is sampled twice per cycle, effectively giving you 2166 MHz. It's not underclocked in any way - that's exactly how it's designed to operate.

First of all, thanks for the input.
