Probably a fool question but I'm a bit lost - Supported CPU's

[juang3d]

Hi there.

I looked for that info, and I found something, but I'm a bit lost and unsure.

What are the supported CPU's by Corona?

I have a renderfam where I have different CPU's, core2quad q6600, xeon 3545, xeon 5545 and amd X6 1090t.

Can I render with my farm in all this CPU's?

Just to be clear, I'm not asking about distribute render, I'm asking about Backburner render.

Cheers.

Foolish questions doesn't exist...

As far as I understand and tested myself corona works on all CPU's as long they support x64 software... you operating system should also be x64 otherwise you can't use corona of MAX 2014

Backburner works fine with A5 distributed will work with A6

use installer and it will work on all of them. benchark wont work on older ones

.....distributed will work with A6

CANT WAIT for this one!
In my farm we have Intel 5x Qxx00-cpus and one i7-2600. At home I have i7-2600k. Has anyone tested is there any differences between AMD and Intel cpus?

Awesome!!!

Thanks! to all :)

Cheers.

BTW. I want to explain why I did this question, I read somewhere that SSE 4.2 supoort was needed for Corona (oviously I missunderstood it)

Why did I read that?

Is there some specific feature that needs SSE 4.2 to have full speed?

Cheers.

[Ondra]

There are actually 2 versions of corona, fullspeed and legacy. Fullspeed is faster, but needs the SSE 4 set. The installer automatically decides which version to use, that is why I asked you to use it on your machines.

I just formatted one of my farm-pc, installed everything and saw in a5-installer that the cpu dont have SSE4. this computer had a problem not rendering scattered trees correctly...Could it be just because of not having SSE4?

[juang3d]

Another question, is the render much more slower without SSE4?

Cheers.

[Ondra]

no, you should get exactly the same result in both, and it is not drastically slower - 20% max

[juang3d]

Great, thanks :)

Don't get me wrong, I mean it well, but all these CPUs together provide less performance combined then a single last gen i7, while I presume each hogs 300W on average during render time.

It's almost never a smart or even reasonable to keep old gen architecture computers for performance reasons (though they can serve excellelently for many other purposes, just not "render farm" ). You pay more on electricity than you get value back in performance.

[juang3d]

Well, they don't perform that bad, a q6600 it's a 25% in performance than a 2600k.

You may think that there is no reason to maintain it... but money is a good reason, I would like to unplug those and put some i7 39xxK or 4xxxK, but maintaining increasing renderfarm power has it's cost, it's not so hard in electricity, and also If I put 1 2600k and I remove those, I have the same performance, If I maintain those, I have doouble performance XD
Of course I want to quit those computers, but I have to sell them and get at least the money for a 2600k/39XXk... and that's hard...

Eventually I'll drop them. but they are also good holders for GPU's for GPU rendering :)

In general lines, I agree with you but money it's what dictates what do I do with the machines, and the yearly cost of licenses and all this things is high for a small studio, so I'm happy of being able to have a renderfarm hehehe

Cheers.

It also depends on the cost of electricity in your contry. Here it is about 0.35USD/kWh

[juang3d]

In Spain 0.16€/KWh, 0.22USD/KWh

Cheers.
