Does the replacement need to be a laptop? For a given price, you will get substantially better performance from a desktop. > In the past I have used PC World and the like > with both of my sons and been amazed with the > disappointing performance. I doubt any general retailers will be able to give advice on Matlab performance. I found this page on MathWorks' web site: https://uk.mathworks.com/support/requirements/choosing-a-computer.html In summary, their advice is "it depends on your application". Matlab is a programming language, so the best hardware will depend on the calculations that your son needs to perform. I have no experience with Matlab, unfortunately, but I do work for a company which produces a compiler for a different statistical programming language. Some operations, such as sorting, can be run in parallel, so many cores are an advantage. Others are inherently serial, so a higher clock speed and better IPC are more important. As for memory, the more the better. Do you have an idea of the amount of data your son is processing? Ideally, you would like enough memory for both source and result datasets, but that may not be possible. If the data is going to exceed available memory, then disk performance becomes more important. A PCI-e 3 or 4 NVMe drive would be a good idea in this case. However, the machine should still have as much memory as can be economically fitted, as it will act as a cache for data on the disk. Has your son tried contacting MathWorks' support? Our support team regularly answers queries about hardware requirements. He may need to supply some example programs, or list the algorithms he uses.
