Corona Render Test M1 and M1 Max

<< < (5/7) > >>

Chules:
First of all, I would like to thank the developers and the corona team because thanks to this rendering engine my work is easier and the results are very popular in my infoarchitecture area. I am a mac user, and I have renewed my equipment. I currently have the latest iMac i9 128GB that apple makes with an intel processor... it works great, I've had it for two years and both cinema 4d and corona work perfectly. I have acquired a mac Studio M1 ultra and it is incredible how cinema 4d, photoshop, illustrator works... a performance improvement is very noticeable when it comes to processing, saving, executing files and plugins. Cinema 4d moves wonderfully, everything is much more fluid. When rendering with corona I only see a slight speed around 10%-15% faster than the mac Studio M1 Ultra compared to the latest model iMac i9. However, Cinebench and Geekbench benchmarks show that the mac Studio is almost twice as powerful as the iMac i9. When I render with corona, that difference is not seen, but when I render with the native cinema engine, yes. I have selected a movie scene and I have rendered it with the iMac and with the mac Studio. The iMac returns a time of 8min-48sec and the mac Studio a time of 4min-56sec. I have a lot of trust in the Corona team and you are the ones who have more information than us. We do not question your work, quite the contrary, we appreciate all the news and corona operation. I just want to add that after several tests I have the feeling that the optimization so that Corona is native in Apple Silicon processors is not being able to take advantage of all the performance of these processors. I can guarantee you that these processors are wonderful because I have 3 different computers with apple silicon and both in 3d and in graphic design I have noticed a great performance improvement in the software I use. I just want to ask you to give this topic one more review and tell us how we can help. Possibly we have to talk to Apple to help us all, because there is some concept of this transition that we are forgetting. I am going to continue using corona because I feel very comfortable with the render engine and cinema 4d, I also feel more comfortable on my mac computers than on windows. My plans are to acquire the third corona license because I want to expand the workforce, but what would make me happier is that this issue be studied again in case there is the possibility of improving the performance of corona render when rendering and taking advantage of all the power of apple silicon. Thank you very much for everything and best regards.

At the end of the day a 10core iMac (20 threads) i9 has much higher speed base clocks than the 20 core Ultra - so there I would expect the i9 to win in certain tasks - and also the Intel Embree rendering libraries that had to be converted to work on Apple Silicon are no doubt still in their early stages of optimisation - so I think there are still things going on/ being developed.

I would like to add that I am trying to pass this matter on to the apple developers to see if they can provide some help on this issue.

Thanks for your comment. The way you explain it, I understand it very well and what you say makes a lot of sense. But... why when I run the cinebench test on multicore is the mac Studio almost twice as fast as the iMac i9? Shouldn't it be logical that something similar would happen with a crown? Is it possible that when those libraries are ported to apple silicon, Corona will return results that are more similar to those of the native cinema 4d engine? I'm just trying to help and see what limits can be reached with these processors and this rendering engine.

Philw:
I agree on the Cinebench - that doesn't make a lot of sense!
