This isn't meant as an advertisement either for ourselves or Intel, but the Pentium 4 or Xeon is the best price/performance platform for HMMER today. Even given the 2Ghz G5 specs published by Apple which won't be available until later this year. Although it's commercial software rather than open source, our vectorized LDhmmsearch and LDhmmpfam for the Pentium 4 are comparatively faster than the speedup reported for Altivec vs non-Altivec hmmsearch and hmmpfam on a Mac. Obviously the G4 and G5 have freely available vectorized HMMER, but even including the cost of our software an Intel cluster can deliver better HMM price/peformance than a Mac cluster or specialized hardware boxes. That said, Mac OS X is an excellent operating system and it would be great to see it available on Intel or AMD in order to really compare apples to apples.
