Phenom 2 X6 1090T

[dcm]

Hi all, i want to buy 2nd rendering pc and im not sure what is the better choice. New 6core AMD or i7-930. I`ve read somewhere that AMD Phenom 2 X6 1090T beats 930 in rendering process but in another situation, where not all cores are needed, 930 wins. What do you think guys ?

Given the choice between the two buy whatever allows you to build a least expensive system.
While the one or the other may have a few percentage points advantage based on a given scenario it usually is not that much.

At some point in the not too distant future I believe GLARE is going to bless us with a GPU based renderer and then the difference in CPU performance between the two CPU choices you presented is going to be negligible.

I can second headroom's comment about GPU.
Waint until stuf about OpenCLL clears up!

For example this could result in a "cheap" but fast Crossfire system with 4 ATI 5750 with a "slow" AMD Phenom II X6 1055T.

I would wait for the math for "$$$ vs Samples per second" until a stable OpenCl build is out and maybe Nvidia has some mid range GPUs out!

I'm not sure that the GPU render is a good way. Because, if you use a GPU for the render of a project who needs 4 go memory with the CPU, you should to have the same 4 go on your graphic card for the GPU render. It's not easy to get this kind of graphic card, some Tesla are like that but genarally, it's one or two Go available on a graphic card.
About AMD 1090t CPU or Intel i7930, it's meaby the same performance. The AMD motherboards are sometimes sheaper.

Wrong.
That's because not the whole scene will be stored on VRAM but only the part of the scene relevant for doing the GPUs tasks (which will be "only" ray-tri intersections I heard)

Exactly. A lot of people think it's an either-or situation where GPU does exactly what the CPU would do. It all depends exactly what the GPU is charged with doing. Octane is fully GPU based, it runs completely on the GPU so that the VRAM is a limitation there. In our case, I'm pretty sure they've got a way of using those 12 Gb of RAM with GPU acceleration for large scenes!

If people have a true experience with GPU render, I' m very interesting to read them.
I was interesting too by Arion render with CPU and GPU render but when I asked random control (Arion render maker) about the importance of the memory on the graphic card for GPU render they confirm what I said before.
If you have a experience with a GPU render with a big project (more than 3 go of memory), I will glad to have the details of your equipement and making.

I guess we'll only find out in the next few days once the first Indigo betas start coming out. I think the reason for the lack of anything before this has been because when it does come out we'll have a fully working version of Indigo with GPU support, not a feature-less work-in-progress.

You'll still want a powerful CPU regardless of what the GPU winds up being Both the 6-core AMD and Intel are very fine processors, personally I'd go with the amazing 32nm Intel - but you pay for it! Be sure to pair it up with 12GB of memory and a good heatsink (very important - bigger ones are quieter and cool much better).

More real cores is always better, but if you go the Intel 930 platform route, in the future you should be able to pick up a cheap 6 core 980x second hand and slot it right in. It is blazing fast. Maybe even an 8 core later on unless Intel changes socket formats, which they usually tend to do...

Going AM3 6 core, is good, and you might be able to plug in the new Bulldozer chips next year that will have 4 and 8 cores, since they are in AM3 socket format.
AMD have USB3 and SATA3 on their new motherboards as well, so if your looking to future proof yourself, the AMD route is better.
