Hi,
The website rendering usually is quite fast, so I suppose that computer upgrade won’t let you very significant change in these terms. For 99% CPU cores will be more important – as the rendering is a separate process, single-core processing will be more relevant in this case. But please remember that in fact every Electron app uses few processes, so multi-core processing can be also important.
The most important will be to use build for Apple silicon processor, because it can give a significant performance change on such device in comparison to classic x86 build for mac OS.
