I actually have a pentium M laptop that I played NFSU2 on during that time. My sister would use my school laptop (we weren't allowed to use my home computer) and I'd use the pentium m machine. I wouldn't be surprised if the pentium m had better single core performance than the A6.
Edit: I found a few benchmarks and the 735 is somewhat faster in single core performance provided that the instruction set is supported.
