Performance enthusiasts: Having finished the MacPyMOL universal binary (http://delsci.com/pre), I couldn't resist running some benchmarks in order see whether Apple's performance claims hold up with respect to PyMOL. It seems they do: At equal Ghz, the iMac Core Duo provides 170% the graphics performance of the old iMac G5, 141% of the single-threaded CPU performance, and 239% of the multi-threaded rendering performance. Even more impressive is how well this $1,300 all-in-one system performs in comparison to a traditional $5,000 Linux Opteron workstation. The iMac Core Duo provides 30% greater graphics performance than my Quadro FX 3000-equipped dual Opteron and is within 10% in terms of raw PyMOL number crunching power (surface calculation and ray tracing). Wow. So with respect to PyMOL, Intel-based Macs have at least a 2-3X better price/performance ratio over dual-CPU Opteron workstations (at least from a commercial vendor like Sun). If you don't need 64-bit computing, these new iMacs are a solid choice for molecular visualization with PyMOL.
