dual processor to dual core


Recommended Posts

Hi

I have a dual processor AMD 2200+ with 1GB and i'd like to go for a dual core AMD Athlon 64bits 3800+ or a Intel Pentium D 820 2.8 ghz Dual core system, 2GB, and a graphic Gainward 6800GS PCI-E 256MB. Is it worth? I primirily use max+vray. Will i obtain much better render times? Where can i find a web page to test a scene in max and vray so i can compare my system with others?

 

Thanks in advance.

Dual cores are going to give you about a 90% increase in speed over what a single processor at the same speed would give. In most cases the AMD chips like the 4400 & 4800 have significantly out performed the Intel version and they are cheaper as well. If you already have a dual processor machine, my suggestion would be to get a dual processor dual core setup so in essence you have a quad processor machine for the same price as a dual processor system.

Abso-frakkin'-lutely do I recommend the dual cores! I've got a 4400 in my new workstation and I am in love. Granted the rest of our workstations are two to three years old, but they get trounced 100-130% by my new machine. The only downside is that now I won't be happy until I've upgraded the whole office...

I am about to buy a new computer for the children. They have been showing to me a Dual core Intel 820. I am not to up speed on specs anymore, is this 820 a good processor.

 

My kids are in college and they want it for their apartment at the school. One of them (they are tripplets) is very much into computers and digital photography.

 

Any recommendations....?

 

Regards

Devin,

 

Thanks for your response. I have dual Opterons on my big computer and I really like this machine.

 

Which is the AMD dual core that I should get? I usually assemble my own computers and perhaps I will have to assemble one for the kids. However, I am not up to speed with the information on dual core, chipsets and motherboards.

 

When I put this Opteron together I changed motherboard 3 times until I got to work right.

 

I have not been reading and Tom Hardware is not what it used to be on the information. What is the highest speed on the Dual Core? Which is the one to buy? What motherboard to use and what chipset should I look for? Has there been an advantage of putting together two dual core CPU’s.

 

Thanks

Elliot

The AMD Opteron 280 is the fastest chip on the market right now and I would use a Tyan K8WE motherboard. I've had two machines in the last 2 years with this brand board and I've never had any problems.

 

My current system is a dual Opteron 275 with a Tyan board and it's twice as fast as my dual Opteron 248, and it actually cost a little less. My office has just switched from buying Intel to AMD and from the bench marks I've been running the AMD 4400 is roughly 30% faster than the Intel Pentium 3.8 GHz, plus it's about $300 cheaper. I've been a big fan of AMD since they came out with their 64 bit processor and if they keep this up I'll never buy Intel again.

Devin and Fernando,

 

Thanks for the information. I have a dual Opteron 250 with 4gb of ram on a Tyan motherboard. This thing has a SCCI raid with a Sata raid as backup drives. This machine is about 1.2 years old and I still find very fast.

 

I had to play with motherboards and memory. I forgot the model number for the Corsairs sticks I have on the board. At one time I had 8gb of memory, somebody suggested I changed them for another type of memory and it made a significant change.

 

I also a have a dual Xeon that I built about 2 weeks after the Opterons. The Opterons are a lot faster than the Xeon, it is a very noticeable difference. The only problem I have with these machines is noise. The Opterons have 11 fans. I used to have the Opterons on an MSI board and that was even more noisy.

 

What memory sticks you recommend. Do you have to fill the memory sockets in a symetrical manner like on the Opterons. Do you have to play with the PEA - NUMA settings when using the dual core. I have aprogram that doesn't really like the NUMA - PEA issue. Is that still the same....?

 

What about Power Supply. I have a 750 watts, is that still required....?

 

Thanks

Elliot

hello

my experiency with dual procesors machine is this:

2.4 GHZ x 2

I talk about that the sum of two processors dont match the velocity of 1 procesor

another thing in render dual core 3 Ghz is aproxx 10% - 15% faster than 3 Ghz HT

 

Can yu tell more about yuor rendering apps? Maybe its up to applications which do not have multithread?

i'm curious why all this ram peeps buy. if you're on a 32 bit operating system like normal windows XP, it'll only use up to 2 gig of ram. only full 64 bit windows will utilise the full compliment.

Unless you use the 3gb switch. In that case I think windows will let any app take up to 3 instead of 2. Typically when rendering in Max & Vray with the 3gb switch, it will crash once it gets up to about 2.7-2.8 gigs, whereas before, it would crash at around 1.7-1.8.

:confused:

as I saw, vray HAS multithreaded optimuisation..

can yu post your scene or at least rendering scores?

 

hello okmijun

yes vray has multithreaded optimisation

sorry the thing is in general for my expertise i have 1 year rendering multiple projects with vray on multiples machines and my conclusion is that, note that the comparision was betwen P D 3GHZ and P4 "HT" both are multithreaded

At work I've a dual intel xeon processor 3.2ghz, 2gb ram, blah blah, which is fast but back in october I bought a new pc for home with an amd 64 dual core 4400+ with 2gb ram, blah blah.

 

I did some test on a project I was working on and my PC in work (I'm using Max 8) was creating frames in 1m45s. My home PC was creating the same frame in 42s :0

 

The biggest difference I noticed was while setting up the rpc content, the amd flew through it compared to the intel. I'm not trying to convince my I.T manager to get me a new shiney amd 4800+ dual core :)
