Which are the differences in performance between Wintel architechture, Linux and IBM AS/400?
Are there any benchmarks around to evaluate the three platforms?

This would be comparing apples to pears.
When Window run on intel (your wintel) and linux does,
Os400 uses mini computers, which are completely different.
Windows also runs on the big Alpa systems (at least nt4 does).
As400's come in sizes, theygo up al the way to almost being a little 3270 (mainframe)
If you have a huge number of users, need databases very big, go for ibm (though the terraserver database is based on "wintel").
If you need a comparison, look for : how do they standout at1000+ webvisits a minute, or:how much sql qeuries can it handle.
Or : does it have to serve files (no good on a as400 or 3270)
It all depends on the use of this server.
In short: large databases that have to serve lots of users => as400
File andprint serving without any hassle =>Windoze or maybe linux.
Low administrative overhead => W2000 or NT 4
Low cost (software) all in one solution => Linux.
Support => Don't use Linux.
TCO => check gartner.
This isn't a good answer, but the best icould give you on this question.
It's all depending, it's better to check what knowledge is "in the house",and try not to change an os depending on benchmarks, because it would be a complete disaster because nobody in the company knows how to configure this "strange" os.
Good luck in making your choice.

They can't be compared.
The lowest AS/400 configuration is more expensive that an 8 processor windows system with 2GB of ram.
Consider first what kind of applications will you run, then select the right os.
Example: I'm working at a bank, we are using 2 as/400 e-series to hold all the critical transations from more than 1000 workstations, at 302 branches. That's the power of 2 as/400. We also have 500 NT servers running different applications, but we can't consolidate say 5 machines into one, due to the os inestability. We are using linux two, have 2 server to distribute email server to 2 domains. Linux is stable but any critical application should not be run here. What if it suddenly fails
