I will soon be in the market for a new computer. Our university has a contract with Dell, so I would be limited to Deel hardware. I am trying to decide between a multicore laptop and a multicore desktop. I'd be curious to learn what Muthen & Muthen as well as Mplus Users have found to be the most important computer hardware considerations in maximizing the performance of Mplus under the Windows 7 operating system? Obviously, one would want to obtain as much RAM as possible, use 64-bit architecture, and have multiple hardware cores. Any thoughts you have on whether a "loaded" laptop has a chance of being as good a performer as a desktop for doing computationally-intensive Mplus runs would be appreciated, as well as hearing what seems to make a difference or not make much difference in Mplus performance under Windows would be appreciated. Thanks!

We don't endorse any particular setup, but we did mention what we used in the Part 1 handout for V7 in Utrecht 2012; see slides 14-20.

The most powerful laptop still can’t quite compete with the most powerful desktop. RAM and CPU speed/cores make the most difference in performance.

CPU is the most important – one could argue in favor of the fastest i7 Quad core. 16 GB memory is fine.

Dell put out some 6-core PCs – but not yet on the office computers – shortly we should have it on office machines. The new processor is called i7 5930K.
