In Tom's latest reviews he does not indicate which benchmark tests focus most on floating-point performance.
I use statistical programiing software with small data-sets (smaller than 1Mb), but the programs are long, often running for days without accessing HD or producing output to screen.
In comparing amd to intel, which benchmark tests should I look at? Is there a clear difference between amd and intel, or are they neck and neck?
Typically, statistical programs would be mostly integer, not floating point. For that, the P4 rules.
If it is floating point, the Athlon may be better. I say "may", because it is basically impossible that it is ALL floating point.
For integer work, look at compression tests like Lame MP3 encoding, Divx encoding, WinAce archiving, etc.
For floating point, mainly check out gaming and 3D rendering benchmarks.
You might also stop by the distributed computing forum (or see if UD or Seti has member stats) and find out what results people are getting from different processors. It seems like your software might be very similar.

Dude, Statistics is all floating point. I guess you could use integers to accumulate data, but why would you? You wouldn’t want to <font color=purple>regress</font color=purple> into fixed point. I mean doubles are almost free on a modern processor and they hold 52 bits of precision.
however intel produces the most stable motherboards, which you will want if you will be leaving the computer on for days
In an attempt to put an end to this lingering rumor I will release the following statement. While Intel chipsets may be slightly more stable for high end usage (i.e. small servers, but AMD has certified motherboards now so this rumor should also be dieing out), AMD boards and chipsets hold a high degree of reliability. I have an Athlon system that runs SETI 24/7 with uptimes measured in months. I have only once in the year and a half I've had this motherboard had the computer restart unintentionally. Once in a year and a half. If that isnt stable, I guess I just don't know what stability is.
