Those numbers only reflect the host machine as it is today.
But the Intel i5 760 started out life as an i3-540

The AMD Athlon 7450 started out life on another machine as an Athlon II X2 245 then became a Phenom II X4 955 which has gone flaky (CPU). I simply put the disk in another junk machine I had lying around. Kudos to Linux. It just rebooted as if nothing happened and WCG just kept on going. Let's see if the flaky machine can resurrect as an i7 3770 using the same disk.

Hello

I am a new participant at this project and I found an old Pentium 4 Northwood 2.66GHz PC in my storage room. I upgraded the RAM to 2GB and replaced the processor fan that was rather noisy with a Artic Cooling F8 fan.

Would this PC be powerful enough for World Community Grind continuous usage?

I worked on few units on it during the past days and it takes between 5 and 8 hours to solve a unit.

According to the Wattmeter, the PC eats up to 120W.

While it may be solve the units in time, does it have enough processing power to be important to the project?

I also participate in Folding@Home with some video cards but the above mentioned P4 system is too weak even for CPU folding (you need a processor that supports AVX to really meet the F@H deadlines).

So I would like to use this P4 PC for World Community Grind projects rather then leave it to gather dust.

Hello Foxter,

Your P4 can run workunits but it's very slow and inefficient.
For reference, my Ryzen 1400 (2017 CPU) runs 8 workunits at a time and draws around 80 watts. An MCM workunit these days is taking around 2.5 hours.

Obviously the Ryzen is much more recent but goes to show how inefficient the P4 is.
I personally wouldn't run it as I don't think it's worth it considering the work it does and the power/environmental factor.

Of course, it's up to you.


EDIT: I should have used another example instead of the Ryzen. My Z3740 (2013 CPU), a tablet CPU, is running MCM workunits with runtimes between 7-9 hours. It runs 4 tasks at a time and draws around 6 watts.

The only caveat to the above two responses is if you would be heating the room containing the P4 anyway the power usage becomes moot and you might as well use the kit you have for a productive reason rather that just burn fuel for heat.

I still have an old P4 which I still use occasionally. It has an old copy of Wordperfect for DOS which, despite its age, I still like to use. As far as a crunching machine, it would be a complete waste of time and energy.
Cheers
