They do, on the same workload. But if you look at the virtual memory breakdown, the vast majority of pages are non-executable data pages. Just did a rough check with Firefox and the executable pages are ~200MiB compared to ~2GiB of Private+Shared Pages. So its not so much the code, its all the data - the graphics, dictionaries, icons, fonts, textures, cached data, etc, etc.
