Pentium 4 Dual processor or Xeon Dual processor

[aligrafix]

Here i am again. posting a new questions for suggession.

I am not hardware engineer etc as well but wana know this:

either dual processor p4 ht (dual core or simple) based system is good for working and rendering in max OR

Dual processor xeon HT (dual core) based systems

because, i need to work daylight and render the scenes at night so my system needs to go for 24 hous working. does this matter on cpu performance if i have p4? because i have noted that p4 based systems give you performance this way for only few months but after few months (working 24 hours) their performance goes down. does this happen or i am losing something i dont know. i have also heard from many people that if i need my system to work 24 hours, xeon based systems have ability to work 24 hours for graphics. they dont let their performance to go down while working 24 hours continously.

 

This means that Xeon based systems are (Trucks) and p4 ht based systems are (Ferrari).

If it is true then is there any difference in performance in these 2 systems?

i need suggession and knowledge before i invest money!

thanks in advance to everyone

i would go neither, price for performance go to AMD. Get ethe opteron 270 or 260 for price to value. And teh y run great. Or some people orefer the x2 4400 to as high as you can afford.

 

But if you want to talk intell. I have an hp xw workstation with duel xeons 3.4Ghz and love it. it goes hard all day for me and is still one of our fastest night rendering boxes. Never fails. But ot buy a new on would be the opteron for me

 

good luck

Maybe you think twice on Intel

[jophus14]

I just bought a pentium4 D 930 last Sunday and it's amazing compared to what I had before. I was leaning towards getting an AMD processor, but I am extremely happy with my Pentium purchase.

In testing the AMD dual-core consistently outperforms Intel dual-cores of similar price.

Does anybody know anything about the issue of working 24hrs of rendering?

by personal trial , I found that there is a difference between AMD & Intel,I think the intels are better as amds usually have much heat ranges which causes permenant damege & performance reduction.

[Greg Hess]

IHAB,

 

Your information is backwards.

 

Current generation AMD chips require less wattage to run, and thus produce less heat, then current generation (non duocore laptop) Intel processors.

 

The last time AMD had chips running hotter then Intel was about 3-4 years ago. Heck the BTX chipset standard was specifically designed to try and maintain situable processor temps because of Intel's overly hot running line.

 

Having built both current gen Xeon/P4 and X2/Opteron workstation, I'd have to say there isn't really a comparison between the two. AMD currently offers the most superior architecture in terms of DCC performance, especially when looking at it from a price/performance ratio.

 

The only intel processors that hold a candle to current gen amd cores are the laptop duocore processors. So you'd actually be better off buying a duocore 2.0 laptop, then buying a 3.4 ghz Dual xeon system, if you had to go with intel.

 

Which of course means (the mac owners will love this), those little white simplified imac's will outrender most current dell boxes.

Intel isn't sitting around and just taking it however. Conroe is slated for a fall/winter release, and is showing a 20% performance gain over AMD's current top reigning chips. Of course alot can change in the next 6 months.

 

If you are looking for a AMD system, I'd encourage you to wait until next month. Socket M2 is just hitting the market right now, and Socket F should be available next month. Socket F in particular, will have support for Quad core opterons...

 

Yes you heard right...that's octal cpu's in a dual processor system. Replace your whole render farm with 1 machine.

Greg, have you heard anything about what price point the new socket F stuff will come in at? Is it safe to assume that the 940 Opterons will drop again like they did 2 months ago and the skt F pieces will come in at what was the old upper pricing tier of the 940's?

 

thanks

I had pentium 4 3.0Ghz, IMB L2 Cahce with 915 GAV intel motherboard. i was working on vray. it took 25 min 30 seconds to

 

render 1 frame. then i upgraded just processor to 3.0 GHz 2MB L2 Cache and the render time reduced to \

12 minutes 15 seconds. it is really great for me by just upgrading processor instead of my whole system. my system is desktop

 

intel based.

i was asking this question (xeon vs pentium4) because i didnt know about 2 issues. i repeat here again,

suppose

1. i am working on a project in 3dsmax. after modelling, lighting and material etcetc. i need to render it in vray and it

 

needs much time like 5 hours etc. i have done other stuff in daylight instead of rendering,. now i shall put my computer on

 

rendering the scene and go home.

This means that sometimes we need to run our computer for 24 hours. does this affects the performance of the system? i will

 

get the same performance after 6 months if i do my work this way?

2. the second is is there any difference between p4 dual core processor and intel xeon dual core processors because i have

 

read some information on intel which shows same tech specs of intel p4 and xeon processors. while price has big difference. i

 

want to know that if both procesors have same archetecture then why people prefer to use xeon instead of pentium processors

 

in servers and workstations? do xeon processors have made for long time run without system crash etc???

i think you people understood what i mean.

Well thanks everybody for sharing knowledge. now i m also thinking about AMD based systems too.

To answer your questions:

 

1. The only worry is overheating. If you are concerned, upgraded CPU heatsinks and fans are available, do a bit or research on sites like tomshardware.com, anandtech.com and web sites for CPU overclockers (because cooling is very important to overclockers). Also, it is important that your case itself have good cooling. When I switched from an old ATX case with 1 fan from the days of the Slot A Athlon to a modern aluminum case with 5 fans, it dropped my CPU temp by 5C.

 

2. The biggest advantage of the Xeon is it supports using two dual-core Xeons in one box for a total of 4 cores. You may notice other, usually underwhelming, differences.

thank you for your answer dear.

well here, intel has no heat problem. well this is really really great information you have added to my knowledge that (The biggest advantage of the Xeon is it supports using two dual-core Xeons in one box for a total of 4 cores). you know what i understood? it means that xeon has 1 chip with 4 cores (4 cores encoded in 1 processor chip). so single chip works same as 2 (dual chip Pentium D) prcoessors.

my next and final question is that

If we put load on the system like rendering at night and creation in day, this makes the computer work without stopping. means continously. does this bring down the performance of the processor or Computer? i have heard from people that if we put heavy load on computers specially computer graphics and rendering, the performance suffers upto 10-25% after 6 or 8 months.

[AJLynn]

No no no, it means you can have one motherboard with two dual-core CPUs. (Note that this requires a dual-socket motherboard, and the two Xeons must be identical models.) You don't get 4 cores in one package until AMD comes out with the quad-core Opteron.

 

For an example of the dual-dual configuration, look at the Dell Precision 670 - you can choose the Dual-Core as your primary CPU, and again as your second CPU. This adds $2200 to this price - and it's only available in 2.8GHz per core. In comparison, something like a Boxx 5400 with two Opteron dual-core CPUs can get higher performance at a low price.

 

Pentium D can only use single-socket motherboards, so you can have a maximum of 2 cores in one system.

 

All of these options can run 24 hours a day, IF you buy a quality system from a good dealer. Realistically, other parts of the computer will fail long before the CPU - hard drives are the first to go, fans and CD/DVD drives break down, and sometimes RAM and motherboard parts fail, but you almost never here of a CPU failing when it's not being overclocked (forced to run at a faster speed than the manufacturer suggests). I've never seen a broken CPU. But for 24-hour use with high-load applications such as rendering, you should ask your vendor for upgraded CPU cooling, just to be 100% safe.

 

Edit:

 

Also, the part about the performance degrading - it would be very unusual for a system's hardware to become slower over time. Usually if a computer seems slower than it was when it was new, it's got something to do with the software - e.g., it's got too much running, crap it got on the Internet, adware, etc.

 

And don't call me dear.

[Kanashimi]

without downplaying the role of the processor which is certainly immense, a sizable portion of performance hinges on the amount of available memory, the speeds of the available memory and the speeds and configuration of the hard drives.

 

the point is, to maximize your system you have to avoid bottlenecks in the overall system. a balanced system is best and if you can afford it hard drives in parallel.

[mattgyver]

From my personal experience, I've gotten amazing results out of a simple AMD Athlon 64 3200+ and I'll be upgrading to a dual core version soon. My other computer is a roughly equivalent P4 and it doesn't hold a candle to the AMD system. Just thought I'd throw in my 2 cents.

[aligrafix]

now i got it. Intel has a good goodwill in my country than AMD. this is because of the heat problem of AMD beicause its hot area. now amd has solved the heat problem and people are switching to AMD. I have no idea of AMD but now first i understood about the xeon and p4. I think i should go for intel bcoz a few people here are intel lovers. Amd has good performance than intel. My next sytem will be AMD now. Thanks to all you guys

[Greg Hess]

Greg, have you heard anything about what price point the new socket F stuff will come in at? Is it safe to assume that the 940 Opterons will drop again like they did 2 months ago and the skt F pieces will come in at what was the old upper pricing tier of the 940's?

 

They should be similar in pricing from the last sheet I saw. Highest two chips being the most expensive of course.

 

DDR2 is also slightly less expensive then DDR1, as it seems to be in greater mass production currently.

 

However...if you needed a whole crapload of ram (like 32gb+), wait for socket F, then buy a normal 940 dual opt system...there is going to be a rather crazy purging of PC3200 DDR when there isn't any "new" systems left that use it.
