http://www.enigmaathome.net/cpu_os.php

This is still a work-in-progress, inspired by distribited.net's table: http://stats.distributed.net/misc/platformlist.php?project_id=8&view=tco

Quite bugged for now (for example, some CPU's - mostly these with low number of results returned - have their speed index way too high). There are some tables missing (CPU+OS, OS versions, I'll add them later) as well as CPUs (some are quite hard to identify).
If you see a bug (other than CPU Index) or have a suggestion, please let me know.

What? No Phenom 9950's? Kinda hard to believe, since I'm crunching with one....;-)

I know some AMD are hard to ID (even with the same family and rev, some show AMD Phenom, others show unknown)

I guess that yours either shows unknown or just the Family/Model/Stepping. I'm slowly adding unknown processors by hand, one by one, so perhaps it will show up later.

EDIT: It's already there.
Btw, these tables are updated in realtime, when the results are returned to the server, the CPU Speed** shown in the table is averaged workunit processing time, shown as relative to the reference machine*. I'm switching off the auto update until tomorrow morning, the script is not yet finished and I don't want to risk the data already gathered.

* - the 'reference machine' for this 'benchmark' is Athlon Thunderbird clocked around 700MHz.

There's also a bug affecting the MAC processors - the wrapper returns 0 seconds CPU time, so the CPU benchmark cannot be calculated (division by 0).

A question. How will the indices be affected {if at all} by hyper-threaded processors running two cores?

Doesn't appear you can edit a post here. Just realised that I wrote "cores" when I meant "threads".

It shows performance from a point of view of a single threaded application.

EDIT: Due to a bug in the calculations I had to reset benchmark score for all processors. Right now the benchmarks are much more accurate.

Quite funny to see FreeBSD on the list, the project doesn't support this platform directly. I got the freebsd app from Lars, but I had some weird problems adding the platform on the server. I guess that someone compiled his own app+wrapper and ran them as anonymous platform.
The same host came with an unique processor - VIA Samuel. I'm trying to figure out why it's not shown on the list.
