There's an itanium 2?

Running 5.6 on an Itanium cluster (linux). It positively screams! It's just a trick keeping the thing up and running (but this is a linux issue)

Can't give you an exact benchmark (yet) but we're looking at a 2-3x speedup over the Dec Alpha which is 2-3x faster than a 300Mhz R12K (SGI). I haven't benched it against a plain old Pentium IV.

Hope this helps.

You should'nt be looking for a speed boost alone when moving from a 32-bit(xeon/pentium) to a 64-bit(I2) platform as it is not worth the investment you make. The primary advantage is that you can now solve problems which require more than 4GBRAM upto (2^64Bit RAM!),ie very large mesh sizes. For a given case the I2 solves about 30% faster than the latest xeon chip

From my experience the itanium performance is pathethic
