As far as Hardware is concerned, I'm of the opinion that newer Opteron x86_64s will blow away Itanium servers. However, with Oracle -- and most non-CPU intensive tasks, the big problem is memory speed and latency. That's where it gets difficult to follow.
The early Opterons made a good move by putting the memory controller on the CPU itself. Although this was definitely superior, AMD was behind in moving their CPUs to support DDR2, wheras Intel had been doing that for years. Eventually, Intel moved the controller on the CPU (and the latest quad-core Itaniums do that) and AMD moved to support DDR2. I can tell you that DDR2 vs DDR1 is a pretty big difference. And benchmarks revealed that on-CPU memory controllers also made a big difference -- in certain applications.
Next we get to IO. Here, it matters little whether the chip is from Intel or AMD. Now it matters the quality of the chipset and hardware vendor. You need to have a very high FSB, and northbridge controllers. PCI-Express x16 and supporting cards should be preferred over PCI based controllers. Fiberchannel and Infiniband are preferred over SCSI, etc.
HP is supporting Linux with their HPC academic and blade-computing clusters. I don't know why you'd have to sacrifice HP support in order to get Linux. Could Linux outperform HP? Maybe not. Earlier, on this board, a poster demonstrated that HP-UX semaphore operations are 4x to 5x as fast as on Linux. Semaphores are pretty crucial when it comes to locking, and Oracle does that a lot. The only way to find out ... is to look for benchmarks that are similar to your environment.
