Which one wold be better - the amd 32 core cpu system

or

a intel sysem running at 4ghz with a dual 2080ti for octane?

those would be the two types of systems i'm looking into - but i'm not sure which would be the faster- 32 cores with native 2018 or 2 latest gen gpu's using octane to render.

anyone know which one is faster system?

how would you even compare the two? is it apples and oranges?

thanks

It will be interesting to see what more knowledgeable folks have to say. Definitely apples and oranges, but if you are talking about pure rendering speed. Then I’m pretty sure Octane would win by a mile. Lightwave 2018 renderer is high quality don’t get me wrong, but not exactly speedy especially on my old 8 core Xeon. Meanwhile Octane is super fast on my first gen Titan and 660ti. I can’t imagine the speed on 2 2080ti’s.

Don't "or" but "+"! ;-)

I'm a new octane user (1 month). Me too I was in that situation: better buy a TR2990 or octane + nvidia?
I have an i7 2600k now. I know for sure that the Threadripper 2990 is about 9 time more fast. The price of a complete computer is between 4000$ and 6000$.
So I got a RTX 2800 (no TI), around 850$ in Italy, and rent octane for 20$ per month.
To test the speed I tried to open some scenes and do all to get a render very close to the render made with lw engine. The speed is about 10 time faster... (some scenes more, some less) (NO DENOISE, I don't like it very much in animation).
This in my work (industrial design, machinery, products). I can't talk for archviz, I read only that interiors need a lot of samples, but maybe with native engine is the same.
Keep in mind that for now Octane doesn't "use" the new RTX, so a 2800 has the same speed of a 1080Ti. Someone says that octane will be very fast when will use the RTX technology (but when?).
I read that a 2800Ti is about 30% faster than a 2800. So 2x 2800Ti how many times will be more fast than a TR2990WX?
Don't take my words as a "rule", I can talk only about my job and about my tests... maybe with your scenes is all different.

Though I don't really understand it, some sort of hobbling was found regarding Windows and Threadripper, where a very bright guy made a solution which has boosted performance.
AMD Ryzen Threadripper 2990WX performance can see up-to 2X Boost with CorePrio tool (https://www.guru3d.com/news-story/amd-ryzen-threadripper-2990wx-performance-can-see-up-to-2x-boost-with-coreprio-tool.html)

I understand a 64 core AMD is in the works, so maybe cpu is not down and out for rendering quite yet.

There is no doubt. Dual GPU + Octane is faster now and will get faster in the near future with all the things they are doing to optimize Octane.

I'll bow to that, but can't help thinking there might be a gotcha or two. The images from this previous LW thread (https://forums.newtek.com/showthread.php?153303-Render-Engine-Battle-vray-octane-redshift-arnold)of render comparisons are now gone, but for anyone who remembers, featured an interior museum shot of a tyrannosaurus skeleton where the Octane image was the poorest (https://forums.newtek.com/showthread.php?153303-Render-Engine-Battle-vray-octane-redshift-arnold&p=1503537&viewfull=1#post1503537)one. The recent images from the RebelHill tuts of cpu LW are very impressive. But renderers never sit still, maybe things have changed since....

As far as poor render quality.. don't worry about that. I'm in the Octane facebook group and my jaw drops everyday.

Fair enough Danner, and many thanks raymondtrace. A question please. We know Octane has plugins to natively integrate into all sorts of software like Lightwave, 4D, Maya, Carrara, etc, but are the plugins essential or can Octane Standalone singly handle those softwares by importing the scene files, allowing a single Octane license to cover everything ?

You can import FBX and Alembic into Standalone, but the best way is to export an Octane ORBX from your app and import that into Standalone, which obviously requires the plugin...

Here's a link to a similar thread I started a few months back https://forums.newtek.com/showthread.php?158039-Choose-your-weapon-GPU-or-CPU-rendering

I ultimately decided to go the CPU route again for now and I ended up getting a 2990WX and it's everything I expected. I wanted to be able to use all the features in Lightwave without any limitations and also wanted to have more RAM available for large projects while also being able to render quickly.

If it were solely about rendering performance, then GPU likely wins outright -- but it really isn't. Depending on the scenes you deal with, there can also be a ton of implicitly CPU-bound computation required for features like dynamics, animation/deformation, and so forth, which currently don't benefit from GPU (but can benefit from faster CPU, or more CPU cores in some cases). It also depends on whether the other tools you use will benefit from GPU acceleration, or are best-suited to benefit from more/faster CPU cores instead.

Understanding your end-to-end computing needs, and what percentage of that can benefit from GPU acceleration, is key to determining how much to invest in GPU hardware.

Hi, I have given up LW native render for Octane 4. My WS is faster than my whole render farm for animation.
Doing archviz, I can render a 4K in less than 4mn. Last week I have bought an RTX 2080TI and installed it on my old WS for network rendering. Octane Network rendering is very efficient and I am wait for Aero RTX 2080 TI availability for adding three of them in my old WS…
P.S.: My WS has a 16 cores Processor…

I'm looking a lot of modleing work.

so i'm wondering if getting an intel with the absolutely highest ghz clock rate that i can get would make sense as that would aid in overall set up of scenes, buliding of models.
i think that is also something to consider.

i may be working more in blender in the future as well, which has gpu rendering or even getting octane for blender and lw.
(quick note if you get octane standalone - will that work for both a octane lw and an octane blender?)


https://ark.intel.com/products/126684/Intel-Core-i7-8700K-Processor-12M-Cache-up-to-4-70-GHz-
this guy goes up to 4.7 ghz which i think is insane speed - but only has 6 cores.
still
a system with this would be the set up modeling system i think (but throw 2 2080ti's in it and its probably good for rendering as well)
and then get the 64 core one for render farm.

then there is this monster - https://ark.intel.com/products/189126/Intel-Core-i9-9980XE-Extreme-Edition-Processor-24-75M-Cache-up-to-4-50-GHz-

which is also high turbo clock.
2k though it would have to come down in price.

its also only .2ghz faster than the amd 32 core. so 32 cores better than 18 maybe i have not seen a comparison yet

You'll want the Octane All Access subscription, which will give you access to any of the Octane plugins. I'm still not 100% clear if you need to purchase one 4.0 copy of one of the plugs first. If you do still need to buy one of the plugs (as your main plugin), do buy the Blender one, since I believe the future of the other one you mentioned is very much in doubt.

And others can help better than me on hardware, but don't forget that you can't go strictly by core count, and that many things out there are single-threaded, and sometimes very high clocks is much more desirable than buttloads of cores. That's what I've read anyhow. I think this might be the case with ZBrush...

I guess I can see why one would think that since Juanjo has his hands full with awesome plugins for Houdini (Redshift and Octane). But I'm hopeful as long as Lightwave is around he'll still make time to continue to develop the plugin, especially since it is so crucial for Lightwaver users. I have confidence in his beastliness...I think he might be my favorite person.

Norka, is there any indication that Juanjo is stopping development or that Octane is stopping support for Lightwave? Any at all?

I'm probably tying myself in a knot here, but isn't it that thing about Norka being asked to prove a negative - like is there and data to suggest any standstill has happened ? The LW thread at Otoy seems to have quite recent activity.

He put forth a position ("I believe the future of the other one you mentioned is very much in doubt") which, if true, has significant negative implications. We're simply asking him whether he has any factual basis for that position (and if so, to cite it), or if it was just (baseless) speculation.

Asking him whether his position has any factual basis is quite different from asking him to "prove a negative".

I would also like to see a comparison. I have a pretty same kind of Intel processor in my workstation.
