I guess there's also the CPU memory handling to consider too............as I understand it, there's an issue with Intel chips and how they access RAM, 'cross-threading' bottlenecks are a worry maybe?

Its standard for most people, just funny for me. I compare it to 'this week I am going to buy 8 engines for my car'.

Why not buy a render farm?... I suppose render farms are more hassle for images, having to merge image after etc.

I always try to avoid a multiple machine workflow, because of three reasons:

1: Two machines need double the physical space and I don't have much space here.

2: Two physical machines produce more ventilator noise, heat and use more electrical power.

3: You always have the hassle of installing and managing software on two machines, licensing all software twice, etcetera.

Thanks deadalvs for that link. A little disappointing, although I wonder how much you could overclock those quadcores. If it's the same as the Kentsfield then you could quite easily get them at 2.66, plus as they mentioned in the review, there is some additional overhead when rendering with so many cores in Cinebench, plus the system wasn't optimized yet to handle the 8 cores. I wonder if Maxwell scales better than Cinebench indicates.

i think that maxwell will scale better than cinebench. but these tests were done without the final processors and they were just put into MacPros without any other optimizations (old architecture, socket 771). all these elements together could give better results on the mac side, but the price is of course the issue.

concerning the price, macs are way ahead of anyone. BUT overclocking these processors needs a BIOS which the new MacPros don't have. i'm not sure if they can actually BE overclocked. (of course there should be a way, but i have not heard of a good/easy one.)
in these macs (sorry about talking always about macs, but at least i mean running them on xp 64 ), cooling is optimized for the processors built-in which could be an other difficult problem...

Hi guys,

I'm seriously considering this one:

http://www.techspot.com/review/27-intel ... page6.html

Maybe a single quadcore will suffice, because a dual mainboard automatically costs a whole lot more, or am I wrong?

I've got a dual Xeon 2.8 GHz right now, so I guess upgrading to a single 3 GHz quadcore system with a lot or RAM (I'm thinking about 8 GB) would already be quite a nice speed upgrade, what do you think?

The processor can can easily be overclocked to at least 3.5 GHz and last but not least: when an octacore is released, it will be replaceable in the same processor socket.

I'd get that one too Metin. From your old system, I'd say you will have almost a 3 times render speed increase.

[tanguy]

but don't forget we are looking for blades and not Tower production...
I am really interesting by the Quad Core XEON but they have to bench it seriously.
We have see next...

Great technical thread indeed

Thanks for your replies guys. Any more feedback is much appreciated, so I will be completely confident what final system I should choose in January.

By the way, is Windows Vista already stable enough to go for? It looks good on the outside, but how about compatibility with older Windows software? And is Windows Vista automatically configured for both 32 bit and 64 bit or are there separate versions available?

[tanguy]

is vista not really draw for this kind of calcul thread ? Cause it s a very big ram eater .... no ?

[MetinSeven_com]

8 GB should be enough, or not?

If xp32 can only access 2 Gig how much can xp64 access?

[tanguy]

i read somewhare that Xp64 start to be different at 4Gb Minimum to accelerate process...
So with a quad core u will have only 2 gig per Core. It good for sure, but not big... What do you think about it ?
If we make one we will allow 16 Gig to have a very large scene sclae possibility.

[deadalvs]

If xp32 can only access 2 Gig how much can xp64 access?

about an exabyte... (mega, giga, tera, peta, exa)

that's about 1000 times all the content of the internet...

that's what true 64 bit should be able to access in ram........ well...

That should be just enough for my needs I guess.

[deadalvs]

i THINK this could be enough for a little.......

ok so when is Maxwell written for xp64?
