Question about switching from Mac to PC for Iray purposes

Been using Daz regularly for almost 2 months now and I enjoy it. I like to animate with it. I'm on a 2017 Retina iMac with these specs:

4.2 GHz Quad-Core Intel Core i7

24 GB 2400 MHz DDR4

512Gb SSD

Radeon Pro 580 8 GB

I'm rendering an animation right now and I wanted to give you PC users some info on where my computer stands vs any of your computers on rendering Iray animations or even still images. I currently have 68 frames rendered at 1hr and 41mins. My scene is a background HDRI map. No scene lights. 1 figure and 1 vehicle. each frame is 2500X1406 (1080p ratio). Update interval (secs): 300. Min samples: 5. Max samples: 15. No denoiser set and nothing else altered in the Iray settings. I get a pretty smooth pics with these settings. hardley any noise. All done on my CPU of course but the fan is spinning fast a long time.

So, what I'm asking from you PC useres, would I totally destroy my iMacs output on just say, a Core i7 10th gen with a 2060 or 2070 Super desktop pc?

    If I assume your system is taking 30 seconds to set up each frame to render, and each frame is rendering for 15 samples, then your system is rendering 1 sample every 4 seconds.  I would expect that a RTX 2070 Super would be much faster at rendering time for this scene (probably 1 sample per second or at worst 1 sample every 2 seconds), in which case a 2070 system would reduce your animation rendering time by 30-50% (I think it would still take about 30 seconds to set up each frame, since that is done on the CPU and not GPU).

    Thanks. I will be making the right choice when I get a PC.

    IRAY does not use AMD/Radeon video cards and is not optimized for CPU rendering. A Mac is completely pointless for IRAY, just get a PC. Oh, and probably you would want to wait until the new Nvidia RTX 3000 series are available again + wait until the developers of DAZ update their software to utilize them.
