AMD 2800 512k L2 or P4 2.8E 1MB L2 DC

Building a computer for 100% DC (LM) use. I know that overall AMD does better than Intel. The P4 2.8E though has 1MB of L2 compared to AMD's 512k. Are DC projects L2 intensive? The cpu's I've narrowed it down to are AMD 2600($90), 2800($122) or P4 2.8E($194). Are the retail fans good enough for 100% duty on a 24hr/day DC project or do I need to get an aftermarket fan? I just ordered a Antec case with a 350w p.s., hope thats enough.

Thanks
 
werd is that prescott rocks seti, definitely any HT chip will beat almost any AMD chip in that particular project

I personally run a 2.8C@3.15 with stock hsf and I don't even think twice about leaving it for the weekend crunching 2 processes, never had a problem while under 3.3ghz 🙂 (Edit: Unforgiven raises a good point about prescott temps, if you want to push the thing an aftermarket cooler might be a good idea)

We'll see how the summer treats her though, that will likely push my temps over 50, still not too bad
 
be forewarned that the "E" pentium 4 chips run extremely hot. the 1 mb of cache is a nice option to have but im not so sure its worth it. a 2.8C would probably be a better bang for your buck and run cooler. then again the cache is 1 meg on the "E" series so thats a huge plus. anyone got any benchmarks between the 2.8C and the 2.8E that they have seen in terms of seti processing times?
 
Did you check out AnandTech CPU page
there are a couple of articles on the P4 E

If I run one instance on my P4 3.0C (@3.3 with stock cooling)hyperthreading computer it finishes a frame in six min. and if I run two instances it finishes two frames in eight min. if the kids are playing processor and graphics intensive game it takes about 12min. to finish two frames, the game is not affected by the Folding@Home clients!
 
I'll go with the Prescott doing a damn good crunching job. My 2.8 does on avg, at least 15-16/day.
 
Hey leconc, welcome to the AT DC forum. 😉

If LM = Lifemapper...then 😀 Being a hardcore AMD fan...I'd say AMD! HT...well...yeah, if you like Intel...lol 😛 If you go for the AMD, I'd say a maybe get a better fan, the retail one will work...but I prefer to use a better one.

LM loves AMD...😀
 
Well, let me put my spoon on it :evil:

The 2.8E is a no go if you plan to overclock.
On the prescott field there is a new player, a new breed if you can call it, it's the new 2.4A.
It has 1MB of cache, but doesn't have HT like it's bigger brothers. I'ts obviously an budget cpu. The good thing is that almost everyone is getting 4Ghz out of that sucker, with stock cooling.... nice. People on prommy's are getting around 4.3/4.4 :Q🙂

On the Northwood department, your' best choice would be to pick on of the recently release 3.0C. Nobody talked much about it, but there is a batch of 3.0 with the same design of the 2.4 and 2.8 M0 cpu's, and if you know what i'm talking about, it overclocks like hell.
Just hand-picked one yesterday, to replace my 2.4@3400, and boy, how things change.
I'm running it now at 250fsb, for 3750Mhz, with two instances of LM, and cpu is at 35degrees.... WOW.. ( on water )
Most people in here are getting 3700/3800 with stock cooling. With water i'm guessing to reach, maybe, with luck 4Ghz...

Let's see...

About the AMD, i don't know a damm sh*** about them. Never own one simgle one in my entire life...

My 2eurocents 😉
 
Most bang for the buck goes to the AMD camp.

I've been running a Barton 3200 400 FSB ($179) in this A78NX for a few months now. Today I got a 2500 333 Barton ($75) for another system. For the heck of it dropped it in my system and I am typing now with it running as a 3200 at 400 FSB. Been running all day, no problems at all and it's 5 degrees C cooler for the heat fanatics out there.

Super sweet for $75 chip.


:beer:😎
 
I've decided on AMD. Do I get the 2600+($90) or 2800+($122)?

Didn't seem like the 3000+($166) would be worth the extra $40? The 3200+ is $217.

All this computer will do 24hrs a day 7 days a week is the Lifemapper DC project. the 2600/2800 seemed to be the point of diminishing returns. I'll use the asus a7n8x nforce2 ultra board and want a amd proc that will be an excellent "cruncher". I don't plan to OC. I'm willing to spend the bucks, just dont want to spend the extra money if I only get 1-2% more for $40, you know. I've even thought about the Athlon 64 don't know if the 64bit thing would really help when I run cli. AMD people, lay it on me, I'll be using this proc for years, I need your advice and experience.

Thanks

Get the 2500-m. It is the mobile version of the Athlon XP 2500. It apparently overclocks quite well, even though I know you didn't plan on it, I'd say go for it!, it's a very painless process of just upping the fsb to 400 instead of 333. Voila: Athlon XP 3200 for $100cdn.

That being said, my main rig is a normal XP 2500, running at 3200 speeds. I benchmarked it (Just using PCmark), and although it's not the best benchmark, it did tell me that my xp2500@3200 was almost as fast as an A643200 on the tests it did do, and for about 1/4 of the price.
 
Well, i think that with a 2500mobile you'll end up good served.

My 3.0C just reached 3.930Mhz, but got unstable... running now 3.870Mhz... Nice cpu
