CRITICAL SPEED ISSUE WITH APPLE M SYSTEMS

[ASIMO]

It seems bitmaps have a big influence in render times.
Surprised to see the i9 13900K (24 cores ?) being so much faster than a Mac Studio.
Interesting all of it.
M3 Macs are coming Monday but I don't think we need to get excited. I wonder sometimes even how many Mac users are still there with Coronarender.

The i9 13900K is not faster than the Mac Studio. When using Bitmaps the Studio finishes the scene in 1:38. The i9 13900K in 2:40 !

Ok, that's indeed something to keep in mind.
M3 Macs are coming Monday so maybe things get even faster.

I hope Chaos is able to fix the bitmap thing. I also think it's wise to handle texture maps with care if speed is important.

The other huge issue with Corona Bitmaps is when you try and collect your scene with assets, those texture links will break. You will need to manually reconnect them. Some have had Team Render issues that point to the Corona Bitmap shader.

Render time for the original scene: 8 minutes, 3 seconds.

Mac Studio M1 Max 64GB
Cinema 4D 2024.1.0
Corona Render 10 Hotfix 2

Thanks so much for all your efforts ASIMO.

OK, I was thinking about getting new Mac, but this thread, oh my. This does not look good.

The original scene from the first post was rendered in 7:40 on my iMac 2020 with i7 40GB RAM, Big Sur.

So, it seems like M chips are useless for rendering and Mac is officially a dead platform for 3D or?  I  see most M2 Ultra results are around 9-11 mins, even if it would be 6 minutes, it would still be bad.  :-/

Saw this review by Geekerwan of the new Apple m3.

Seems that the GPU raytracing (blender/redshift) on m3 is beating the best Nvidea laptops. Which we all thought would never happen.

I was thinking I will sooner or later go PC but after seeing Geekerwan's review I am not so sure anymore. The new Macbook m3 max is already faster by a wide margin compared to my m1 Ultra.

And just for a laugh on PC's if you switch the sound on:

well, they seem to compare it with an ultra low end nvidia model 4060. this is the lowest available nvidia card, many times slower than a 4070,4080 or 4090.

to be honest i would not could to be the m3 any near an modern 3d pc(not gpu not cpu) with modern high end specs. same wonders had been said on m2 which didnt become true.

[frv]

I am a Mac user so I am always wondering if or not to go PC. So the 4060 Nvidia is the worst card in the Nvidea line up and the m3 as useless as well. My son though has a 3090 card in his PC and it seems to do very well.
Anyhow, we will see sooner or later how Redshift runs on a M3. Rendertilmes for me don't matter all that much, modelling, interactive rendering much more.
We should compare laptops with laptops though. A dedicated 4 or 5K € desktop PC with liquid cooling will obviously be much faster and the better choice if you render for a living.

I have seen benchmarks that show that the m3 max is just as fast as an m2 ultra. If this is realistic, could it be that an m3 ultra is 2 times faster than an m2 ultra? That would be an incredible increase in speed. Wouldn't it? The question is whether these are realistic considerations on my part. I'm wondering whether I should buy a PC now (as a Mac user) or wait for the m3 ultra.

I think the best we can predict for now is that it will have 32 cores!

The M2Max vs M2Ultra wasn't a linear 2x performance - but who knows?

I think it will be a great machine and take a fraction of the power from the wall vs a PC equivalent - which is the important factor in my mind right now from a cost of living point of view.

MacPro M3 - 32GB- C4D21 - Corona 10(hotfix2)

Original Scene 7:31

(my previous MacPro M1 was 9.59)

[Philw]

R21?

That's pretty good as it will be running under Rosetta emulation...

[mat]

Corona 10 Benchmark :
Apple M2 Ultra = 11 098 587 rays/s
Apple M1 Ultra = 9 183 200 rays/s (mine with 128 gb)

AMD Ryzen Threadripper 3990X 64-Core Processor (3.22 GHz) 128 GB = 22 645 798 rays/s

[frv]

Is a 68 core (136 threads ?) only twice as fast compared to a 24 core Mac ? Or is this not a linear thing. Will a new m3 ultra be as fast as a 68core thread ripper....

[BigAl3D]

For many years, the number of cores on the CPUs of the same speed would indeed scale that way. 8-core was twice as fast as a 4-core system. At least with C4Ds native engines. Not sure anymore with the new render engines and the new ARM chips. I miss the days when the new chips would make a big difference in speed.

Like the new iPhone. All i see them pushing is "now with Titanium!" which will look great all covered up by my Otterbox. Not sure it's a better phone than the 14, but it's got Titanium!
