Are Dual Opteron 4284's any good for Rendering

Hi im currently running a ASUS KCMA-D8 socket C32 with two rubbish 4122 cpus(8 cores), 32 gigs of ram and a GTX 480. Currently the system is capable of most of the things I use it for (Modelling, Rendering stills, after effects, photoshop etc) but I am definitely wanting more rendering speed..Saying this would it be worth upgrading the cpus to say Dual Opteron 4284's which would give me 16 physical cores running at 3ghz?
These cpus look good on paper but I cannot really find any definitive benchmark figures or any info apart from sales, promotional rubbish...Saying This I have read some interesting info on folding forums, apparently this board/setup suffers badly with memory performance and thus overall performance..So saying all this I guess what im asking is, is anyone using a similar setup for production rendering? and how are you finding the performance? and would you recommend this setup?

I think the fact you cant find a single benchmark of it (I found one but its wasnt useful) probably says it all. The best setups tend to be popular because theyre the best speed or value, the only thing I can find on these chips is people saying how utterly disappointing they are.

Run all the tests in cinebench, including the single core tests, tell us what your current system gets so we have a starting point of where youre upgrading from.

It would be about $700 for the processors, that's a lot cheaper than building a new machine. They might not be the fastest but I doubt you'll be able to build a faster machine for less than the $700 you could spend on processors for the machine you already have. A rough guess would be around 10.0 or 11.0 on Cinebench, but I haven't seen anything to substantiate that.

Just got round to running Cinebench x64 and got a 4.97. Is that good or bad? I agree about the cost side of things, on paper this setup looks like it will perform but from my experience so far im not so sure! Just wondering if I could get better performance with a single cpu setup, which would be cheaper and I could use this rig as a Render node for DR and things..

If you want faster renders for as cheap as possible, get the newer processors for your existing setup. If you want faster renders and you don't care how much it costs then you could build another machine with faster processor(s). I would estimate the Core i7-3930K to have similar performance to the faster Opteron processors (which are from 2011 to be fair). That Intel processor is about $600 by itself (plus at least the motherboard and memory) and there are faster options that just get more expensive from there.

Well lets put it this way, a score of 4.97 is what you'd have gotten from a sub-£1000 machine 5 years ago. Im honestly not sure I'd upgrade it, the single core speed would be mediocre at best, with the render speed only just coming up to par with a single cpu with 4 cores, let alone having that power thinly spread over 16 cores.

Come on man, you're just trying to make the original poster feel bad now. No quad core out there right now would keep up with the faster Opteron processors. At best a quad core Intel overclocked to 5.0GHz will do a 9.0 or 9.5 in Cinebench and that's assuming you could even get it to overclock that much. In my opinion upgrading the processors is a reasonable option and would cost less than building a new system. If this were a clean slate for a new build I wouldn't recommend the Opteron processors, but that isn't the case and the existing system has some value. If there's money in the budget for a new machine by all means that's a better option (like $1,500+).

My i7 4770K @4.4 GHz is doing a MP vaue of 8.86 and a single of 1.87
CPU temperature stays below 72°C at all times, the fans don't even speed up.
This for just slightly over €1K including 32 MB.

For far less than 1k euros I got a 4770k with a cheap h50 that's comfortably runing at 4.7 and spare change, that's with an asus pro mobo and 32 GB of g.skill ram.
Could have shaved off more for cheaper ram again and for a mobo that doesn't come with a decent audio card, blue tooth, wifi with external antenna and all that.

Sorry Olson, but without wanting OP to feel bad or anything it's true you can easily par up or top that config in full out multithreading, and absolutely cream it in single/penitent threading operations with a single i7.
It's true that it wouldn't be 700$ though, it'd be closer to 1k, but surely not 1.5+.

I would probably try for a sale while there's still a chance of it and move to a more recent platform personally.

Im not trying to make anyone feel bad, but I do think its best if the OP realises that his original investment wasnt great and that upgrading it now would just be throwing more money into the pit. Don't take my bluntness for cruelty, this is more Simon Cowell telling a tone deaf guy he can't sing.

If he gets the upgraded processors, the render speed will be about equal to a high end 4 core intel i7 machine, with high end still being less than a grand. But his single core speed is still going to be somewhat feeble.

My advice is to sell the current machine and use the £600 he was going to spend on new cpus combined with a few £100 he sells the current machine for, and buy himself a 4/6 core i7 machine. Other than getting the render speed he was after, he will also dramatically improve the editor speed and more than double the speed of all the single threaded parts.

On top of this, keep in mind cinebench is a few years old now, newer versions of c4d will be taking advantage of updated instruction sets in the newer cpus, so I'd also reasonably expect the new i7 to gain a further 20% lead over the opterons in real terms.

Thanks for your comments, Ive taken all of it on board.. The main thing which I should have mentioned is that this is also an all round machine. I do alot of video editing as well so need tons of ram, I have yet to look into the i7 side of things (Always stuck to 2P Amd in the past) but will need more than 16gigs of ram for sure. I will do a little more research into the intel motherboard side of things and price a few alternative options up to see what gets me the most for my money. At the moment this computer is costing me money through being to slow render wise, for the rest of the things I need it for its perfect though..Its just a shame there isnt a little more info about the Opteron 4284s or the new Opteron 4300s which this board also supports. Aditionally its annoying you cannot overclock this setup as it would probably get me where I want to be speed wise..As a side note I have found some cheap 4284s totalling £400 posted, so unless I can beat the performance 16 cores @3ghz is going to get me im not sure a full upgrade at this point in time is feasible financially...

If you do video editing and need TONS of ram, than X79 is the only mainstream solution, to avoid extra high price Xeon mobos etc....

95% of x79 mobos have 8 slot for RAM, and support til 64GB of ram, no everyone please check it before buying.
best!

Any Ivy Bridge or Haswell will very comfortably sit and run 32GB of relatively cheap ram in 8GB sticks x 4 banks. They also tend not to be as picky or poorly performing with intensive ram operations as AMD's offers.

64GB is a different thing. 16GB modules are usually registered/ECC and overly expensive, and 8 banks are only common on the more expensive mobos.

But you seem happy with where you are (32), and 8x4 of quality 1866 ram is sub 300 these days.

Not right, almost every X79 has 8 banks, 200$ for mobo is not astronomic price.

You're absolutely right.
I was thinking of current Haswell offerings with that part and made a bit of a mess of my post for it.
