boinc machines
At BOINCstats, they have lists and lists of information about which types of computers have contributed how many units in recent days. And part of my interest was actually seeing where my processor is relative to other processors, just to see what I can expect. One of the things that's interesting for me though is that the mac pro machines (which all get the same identity on the lists, whether they have 2ghz or 3ghz processor) are very near the top - as can be see in this list. (check that the list is sorted by average credit per cpu, and then look at the fourth item down) or have a look at this list where you can see a fair few machines which regularly average above 2000 credits per day! That's 10 times faster than my Intel P4 @ 2.8ghz.

Do you mean Mac Pro Intel Chips, Do you mean MacBook Pro? What kind of intel chips core duo, or core 2 duo? "Mac Pro" is pretty meaningless when it comes to CPUs. :)
The new Intel chips do rock by the way. A P-M 1.8ghz performs pretty much the same as a P4 2.8ghz. Then Intel went and did the Intel Core Duo (a dual core Pentium M but better), and then they went and did the Intel Core 2 Duo (a dual core "Duo" but even better again), and soon / now they are releasing Quad core chips that are going to be even better still... :)
The only existing 'Mac Pro' is 2 x Xeon processors: Inside every Mac Pro resides two new Dual-Core Intel Xeon “Woodcrest” processors. Running at up to 3GHz.
Cool - so what matt's saying is that a 4 processor machine (running 2 x dual core Xeons) is 10 times faster than one p4 2.8ghz cpu. Makes sense :)
If they are running at 3ghz and each one is based on the Pentium M which clock for clock is generally twice as efficient as the P4, then that makes sense.
Hopefully soon quad core will become affordable in PCs and you can recreate the Mac Pro yourself, but in a cheaper PC. The Dual Core Duo 2 chips from Intel are relatively affordable (around £200) considering the massive amounts of performance you get from them. So it's all good :)
Have you got hyper threading going in your os? Thats like another cpu for free.
I have a petium M (or actually a celerom M) at some stupid over clock. It gets a RAC of 333, but annoyingly its not in that list you reference. If it was it would be around 26-27th, but as the list of the top 100 host you are seeing number of CPUS and length of time in the project getting them in the list. It would be interesting to see RAC per CPU list.
My gut feeling is that petium M is worth a P4 3.0gig with hyper threading, and actually may be a wee bit slower. Buts I don't actually have any P4s doing seti its really just a feeling
