The VS4k9 is around 24 VUPs. It compiles quite exact twice as fast as my 4000/60 that is rated at 12 VUPs. I have seen many confusing ratings for the VS4k90. It is a nice desktop machine. Especially as mine has 128MB RAM. But it is a joke to that VAX7650. Damn. I would sell my grandma for that machine. ;-)
