It depends. iPhone has slower processor but more memory. It might be faster than iPad on memory intensive applications (if there is any sort of memory virtualization involved) but other than that iPad should be faster.
My 3G score is a whopping 142

I have an independent set of micro-benchmarks, both integer and floating-point intensive (and stuff that can't go in the App store, such as language interpreters). They all take in the range of 20 to 30% longer to run on my iPhone 4 than on my iPad (wifi).
That still puts my iPhone 4's performance in between my old Beige G3/266 Mac and iBook G3/800, in performance, for everything except double-precision floating point number crunching.
ymmv.
