It's a teeny bit slower if you don't need it. The structures describing pages of memory [known as PTE's] are larger, so take up more RAM, and take bit longer to fetch, but in practice, you'll usually not even notice the difference. It's hard to make it show up even on benchmarks with modern CPUs.
Is it good enough that we can consider making the default kernel PAE and dropping the variant? That would make QA easier. In FC6, one of my top favorite feature is dropping the separate smp variant.
