I'm looking to purchase additional mid-level dedicated servers to handle shared hosting accounts, and would like to hear some opinions on what kind of systems I should opt for to get the best bang for the buck. I'm debating between a Pentium D and an Opteron, but would also like to know how they compare with single-core P4's and such.
Can I expect to host 1000+ low-to-medium usage hosting accounts (~100mb disk usage and ~500mb bw/month each) on that one server?
... bleh. Just lost my original post. Lynx is annoying.
Anyway. The AMD Opteron line of CPU's are far more powerful than any Intel CPU before the Xeon 5100/7100 sequence chips. There is an interesting 'VPS vs. Dedicated Benchmark' thread going on which you can find by searching the keywords 'vps dedicated benchmark' that will show many real-world examples, many of which are Opterons and Pentium D's.
I have a very long experience with both Intel and AMD CPU's. AMD Opteron's have always been worth the price because of their far superior power (compared to the Pentium D line of CPU's).
My latest web server actually uses the AMD Opteron 270 CPU's. Those CPU's are more powerful than the Xeon 5000 sequence CPU's, and the Xeon 5000 CPU's are by far more powerful than the Pentium D.
