Pentium D (Dual Core for D2OL?)

[Rodzilla]

I'm curious as to know how these stack up? Anyone running one? Is the output of a Pentium D 3.0 GHz compairable to two rigs running your typical single P4E 3.0GHz W/HT????

I don't know about the other P-D's but this 840EE does about three and a half a day @ 3.6-3.7ghz

Only down side to that is the cost. But Damn!!!!!

[[KoG]^weaZel]

the standard P-D should be in the same neighborhood as that but at a much reduced cost. And not to mention they should clock better than the EE as well. The heatsink on the VRM on the p5wd gets HOT under load with this beast.

So from single core to dual core... It's very close to 2x the cands! Nice! I'll have to look into that!

D2OL was one of the reasons I build this DC EE machine. I just :slobber:'d when i thought about 4 nodes on one cpu. I was not let down by the performance of this machine.

[WesM63]

Weazel,
That really clears up my 650 vs 830 question now don't it ;) Even then I think i'll opt for the 820 (2.8ghz DC).

[MRBIGSHOT]

me to. now to find a mobo that overclocks well and isnt 200 or an asus

[perkam]

Even then I think i'll opt for the 820 (2.8ghz DC).
The 830 and the non-ee 840 aren't good buying decisions considering the 820 can scale to 3.6+ on air depending upon cooling and mobo chipset.

I want to hear more cands/day results before i go and spend more money... Is it better/cheaper to go out and get a Dual LV Xeon rig... or a P-D rig?

[perkam]

or a P-D rig? P-D rig, hands down...if you buy from newegg/monarch i could even give you exact links to most reasonable parts you'd need for one. Are you going DDR2 though, or DDR1 ??

A DX rig can be built for ~500 > 600
I'm looking at almost half of that just in the P-D Chip... (BUT the board can't cost no $200 like the PC-DL)

I'm intrigued!

I wonder which would require less power... which would generate less heat???
This will be a MAJOR determining factor... as I'm all out of available amperage in the house... and It just WAY to hot unless it's 50Deg outside.

.:EDIT:. I don't want DDR2... I own nothing but DDR1 and would like to keep it that way so I can juggle ram around if I like. I don't want proprietary parts lying around if I'm not happy with how a given set of ram might perform in 1 rig.

[perkam]

I wonder which would require less power... which would generate less heat??? P-D's are going to run VERY hot and eat up a lot of power I'm afraid...But yea, a good mobo costs $110...And about $40 more can get you a good cooler. On the brighter side, its an updated platform and VERY futureproof.

Perkam

I do D2OL and I'm a gamer... that's really the only thing I need to think about when upgrading.

From what you say... I’m better off going the DX way... Heat and power are very important. And the LV DX rigs generate little heat and use little power. And with my DX rigs averaging about 320/day conservatively...

And as of now games run for crap on a DX rig or a P-D... When true multi-threaded apps come out we will see the gains. (How long has HT been out and there still isn't a multi threaded game out on the market) So I guess P-D isn't for me :(

[perkam]

So I guess P-D isn't for me Np...its not like anyone was owning the orb with one ... :shakes: at intel for screwing up dual core.

You missed out, there was a guy selling brand new PC-DL mobos, not OEM, for $150 + shipping on ebay.

Only thing about them boards are they were the old revisions.

[MRBIGSHOT]

you are not adding much power draw with a duel core, at most 86watts.

[jahjahbinks]

My 830D with a sound card and a Geforce 6800 consumes about 270 watts when both cores are at 100%. However the overclocked 2800+ I had before (at 2.5 gig) with no sound card and X300, consumes only 120 watts. If electricity costs a lot in your area, invest AMD.

Yea... AMD does run much cooler and draws less power... But Intel does better in D2OL... Hmmmm.

p-d has no ht, so I think, that the output of a 630 with ht isnt much different to a p-d. sure, a real core is a little bit better than a ht-core, but imho its not worse the money to spend so much for for a dual-core.

When you are talking D2OL... A dual core would win hands down over a chip with HT. The increase from running HT isn't even close to 2x. Everything that I've seen says that a P-D will do very close to 2X or more where D2OL is concerned.

ok, didnt know that, i thought ht doubles the output of a p4. but if your are right, a dual core will blow a p4 away :)

edit: good to have you back on board rod!

Thanks!

I've tried running P4 rigs with and without HT. HT always gives you a very noticeable increase... but it's only 30 to 50% more. The P-D numbers I've seen people report are a good 200% better than one of my "comparable" P4 setups.

I can safely say that if I wanted to upgrade my main system for gaming and light surfing... I would get a straight up P4.

For me, because of my heat and power issues, a Dual LV Xeon rig seems to be the way to go.

If I weren't limited by heat and power, I’m still not too sure what I would get (And by power I mean the physical ability to supply it to the rooms... the bill isn't too bad) The whole thing I’m struggling with is the dollar for cand ratio is very tight... the P-D is capable of more output... but cost more to purchase... and requires more power. The DX rig is a little cheaper, puts out a few less cands, but requires less power to run (and less energy to cool the room it's in)

We have ourselves quite the paradox...

[ex2cib]

you could think about getting an X2 if you are concerned about power, heat. there are a few guys in the CM (vapor and bullet that i know of) that have X2 clocked @ least 2.7. if that is comparable to my venice at 2.7, that should be @ least 300 daily with moderate usage. and if it got left all by itself for a while, maybe in the 330-350 range. i could be slightly wrong with those numbers, but you'd have to ask them about it.

[jahjahbinks]

But Intel does better in D2OL... Hmmmm.

No, my Intel is slower than my AMD, 200 candidates vs. 300.

[Absolute_0]

Yes, if you get a 3800+ and give it a decent (2.6+ Ghz) overclock, you will do over 300 a day.

OMG you just added a whole nother level of maddness!!!

So lets get some feedback on the X2 setups... I know DDTUNG might be getting a couple.

What is your Intel and what is your AMD?

[jahjahbinks]

how come no one has answer my other thread?

[jahjahbinks]

Intel is 830 stock

You should be getting better than 200 on that intel... are you running 2 agents on it? That and you are comparing an overclocked amd to a stock intel...

Well, slightly more than 200. It's not a farm, I browse internet, play games on it, so can't expect full output on it. My AMD is a farm one. Well, at least it is after I tweak RAM timing.

[KaptainBlaZzed]

setup X2:
3800+ @ 2.85
2 x 512mb (2-2-2-5)
DFI NF3 Ultra -D

I get at least 320 per day with my X2 and i use it everyday. on a good day it will do ~350 and on a day i decide to game for a while i will get ~300.

and on the heat issue my X2 @2.85 puts out the same amount of heat as my single core P4E 3.2 @ 3.7 maybe a little less. If it is going to be purley a D2OL machine i would get another DX but if you plan on gaming on it go with the X2. just my 2 cents on the issue.

Yea that's kind of what I expected. Your P-D should be pulling down slightly more than the X2 if you OC it.

If I had either of them chips I would run it for you.

I haven't seen any Dbench results with these X2 chips... I may have missed them. Can you run it for us?

That's a full 30 seconds faster than the bench I ran on one of my DX rigs! :up:

[Rodzilla]

I want to see what a P-D can pull down... similar clocks for comparison.

[Martijn]

I can do 200-300 with my 820D @ 3.18. This is dedicated 24/7 though, and I use it a lot, so I never get over 80 or so...


At stock, it is about 25-50 lower.

I know those Pentium D'sx must look awfully good but they are just 2 presscots slapped on the same die! Liturally.

Plus I think a pair of 2.4M0's would be better then a P-D rig. Why? because they are dual AND have HTT so you CAN run 4 instances on those.

I don't know how good they are compared to a good clocked Pentium D but I still reckon a good clocked DX rig will blow a P-D away

Even the 1.6GHz LV D1 chips would do a little better I would imagine. That's why I'm interested in seeing a Dbench result from a P-D.

That doesn't sound right... did you turn off D2OL to run the bench?

Did you run 2 copies simultaneously, take the results and average them, then divide the average by 2 to get your Cand/sec result?

[Absolute_0]

With my 3800+ that i use all day long, i clocked off 330 candidates/day the last time i measured it. Fully dedicated it must be in the same range that KaptainBlazzed said, at least 320-350.

Yes, I open up window manager to make sure cpu was at close to 0% before running it. And 2 copies too.

Is that a new term/feature for the dual core chips? :confused:

[jahjahbinks]

No, i just have that disabled for my AMD chip. But I don't think that has any effect on speed though. Intel single core has that feature too.

Maybe instead of comparing candidates per day, we should compare comformers per day.

I don't care if it effects performance but DEP is OFF here. I don't have a pentium D or something but on my Sonoma laptop I do. It once stopped me from opening a RAR file I am 100% sure off is good. I mean, I made it myself and I ran it tens of times before.....


DEP goes off here. Just because it sometimes stops software like bin2iso or even a RAR package...


and yes please on the 840 EE scores :)

yeah, i want to know too! :banana:
