Having the BOINC database down put a severe crimp in our production. I'm glad it is back up.

Merry Christmas everyone!

Nice one D and crew

Superb Job

Welcome Delaz

Interesting.

I decided to do a comparison of my various machines. (Sadly, I can't edit my earlier post on the subject, but things have changed a little.)

Doing just the basic 'CPU Benchmark' built into BOINC, I have compiled the following stats of average MIPS/MHz. (MIPS being an evenly weighted average of both Integer and Floating Point, MHz being just what it says. Processors with two cores have MHz doubled to account for their ability to do two full-speed calculations at once, processors with Hyperthreading are only counted once.)

The winner, by far, is Core Duo. My Core Duo 2.0 GHz gets more than double the Integer MIPS of my Pentium Extreme Edition running at 4.0 GHz, per core. That means that ONE core of the Core Duo is faster than BOTH cores of the Pentium-EE when doing integer work.

Core Duo: 2.905 MIPS/MHz
Pentium M: 1.357
Celeron M: 1.271
G3: 1.054
G4 (average of two G4 computers:) 1.025
Pentium Extreme Edition: 0.976
Pentium 4: 0.600

That's right, a G4 is more efficient, running only one thread, than a dual-core Pentium 4, on a MIPS/MHz basis. Of course, nobody makes a 4 GHz G4, so that's a bit of a moot point.

The best individual score is the Core Duo on Integer work, at 2.128 MIPS/MHz (per core,) the Pentium Extreme Edition, on the same Integer front, at 0.491 MIPS/MHz (per core.) At that rate, a QUAD-CORE based on Intel's (now dead) NetBurst core at 4.0 GHz would be beat by a single-core 2.0 GHz Core-based processor. The absolute worst score is the plain Pentium 4 on floating point, with 0.477 MIPS/MHz. (None of the machines beat 1.0 MIPS/MHz on floating point, while ONLY the NetBurst were under 1.0 for integer. The PowerPCs were all around 1.4-1.5 on integer, and the Celeron M and Pentium M (same basic core,) were at 1.7-1.8.

(The changes in my lineup are that the 3.8 GHz Pentium 4 670 is now a 4.0 GHz (overclocked from 3.73 GHz,) Pentium Extreme Edition 965, and the 233 Mhz G3 has been retired completely. All other specs the same. So now my MHz total is up to 21,210 MHz, 5798 MB RAM. (Hrm, I miscalculated last time on the RAM.) And to think, someone overclocked one of Intel's new quad-core Xeons up to 3.0 GHz. One dual-socket system of that would be me in total GHz of processing power available!

crunchin&munchin for a cure!!!
