A year or so ago, I had a small amount of cash, and decided to buy a couple of cheap pc's. Havin had Celerons in the past, I decided to go with the (then) new P4 Celerons... I regret it so much!!!

If you check out my computers - you will see both my 1.7Ghz and 1.8Ghz celerons (both with 512Mb SDRam) being beeten by... wait for it...

And Old P3-550Mhz, and a S370 Celeron 700Mhz!!!!!

I just dont get it! How can a P3 700Mhz Celeron by much faster than a 1.8Ghz P4 Celeron???

I want my money back! From now on, ALL new chips I buy will be AMD!

Good - Feel better now thats off my chest!!!

Happy New Year to you all!

Cheers, Nicholas

I believe, from what i have read in some other threads, that the problem with the Celerons is that they are simply not designed to crunch the numbers. So while they deliver decent speeds and general usage capabilities, they are hopeless when it comes to hardcore math crunching.

---

Kolch - Crunching for the BOINC@Australia team since July 2004.
Search for your own intelligence...

It's all about the cache (well a large bit is)...

The old P4 Celerons also only got 128KB Level 2 cache. The Celerons before that had 256KB as do the newer ones. (now even up to 512KB of cache if I am not mistaken).

That hampers in downright crunching.

---

It is also not just about raw MHz ... Cache issues aside (though they are critical), the internal architecture can make a huge difference. For example, if we look at the internal instruction pipeline, and the old P3 had, say, a 5 stage pipeline ... if we have "stall" in the pipeline we would lose 5 clock cycles (keeping this simple). If the Celeron has, say, a 7 stage pipe line we lose 7 clock cycles for the same "stall" ...

This is another factor and why measuring MHz is not totally relevant even in the same processor "Family" ...

In theory, the longer pipline allows more efficient flow, but if there are stalls, well, sorry about that ...

And I won't point out that a 2 GHz G5 is as fast or faster than a 3.2 GHz P4 ...

You cant be configured properly. I have Celeron 1100MHz completes work units in 7hr/40min average, Celeron 700MHz average time is 11hr/20min and also have P-4 Celeron 2600MHz average time 5hr/40min. I also have an assortment of AMD processors they both work well.

Can't work out what is wrong with my 1.1. Used to run them in the same time as yours. 8hr mark. Now it's taking around 14hrs for some reason.

Thanks for the explaination guys... Now it makes sense! I have the early 128k cache versions...

Paul B: LOL. I won't mention how my Athlon64 at 2.2Ghz mashes anything intel has to offer (nearly... ;o) if you don't mention your G5! ;o)))))

I just got a couple of proper P4 1.7 gig cpu's off ebay... so the Celery's are history. They are going in the bin, or if someone here wants them I am happy to part with them for a small donation to the SETI project... My email is nicholas@cload.com for anyone interested.

Thanks again!

Nic.

Nic.,

And I am waiting for the next generation from Apple ... Best guess it will come out in June/July ... but I may not have the cash till November ... I think a 3.0 GHz G5 is really going to scream ... Heck, I play music, do BOINC and work on my web site and hardly ever see a hiccup ... runs smooth as silk ...

If you're serious, and if they work fine, I'll take them! What speeds are they at?

---

You will be assimilated...bunghole!

1.7 & 1.8GHz.

I could use them! I sent you an email. I can use my UPS account so you wouldn't have to fork over shipping.

Your giving away 2 processors? Why don´t you just keep them running BOINC ?
Just wondering :)

I would do anythng for another processor.

The reason I'm giving them away is because my Celeron 700Mhz is fast than they are... So I am upgrading them to REAL P4's. I'm not buying new memory, mobo's etc, so a couple of spare junk cpu's is a waste of space for me...

I would love them to continue processing seti, and they are worth $15 each on ebay max, so I'm giving them away!!! ;o)))

For a small donation to seti of course... ;o)))

Borgholio is the lucky winner! ;o)))

Agree. My P4 Celeron 1700/128L2 completes WU fine in a range of 7-9 hrs, but I run other tasks as well.

If you dont have takers on the Celerons I will donate $15 in your name to the cause for one of them.

My 1.5 P4 (not Celeron) does an average WU in 5:50

why not just go for a new motherboard from DFI and put an pentium-M in your desktop, they have 2mb L2 cache and can be cooled passive, and they complete a WU in boinc in 2 and a half hour, when also running seti@home classic.

---

the 2 and a half hour is for an P-M 1.7ghz Dothan core
