SGI Altix benchmarking whitepaper

Results of the tests revealed that the SGI Altix 330 using shared
memory and unmatched I/O throughput achieved superior
performance and ran faster than twice the number of cores in
comparable AMD dual core Opteron-based systems.

They also chose fairly slow Opterons (2.2GHz). They've chosen a set of applications (FP-intense MPI codes) which are bound to favour Altix-like architectures, and the Itanium2. Plus the observations others have already made. For integer based and embarrassingly parallel workloads where the interconnect doesn't matter so much, the difference will be much smaller, and probably in Opteron's favour.

But all that aside, I still want to ask the question: how much more does the 16-way Altix 330 cost than the 8-way dual core Opteron? What's the price-performance?
