Make sure you are rendering on a computer with at least 6 cores and supporting hyper-threading. 8-core processor would be better.; GPU renderer would help accelerate both your video rendering for preview and export a lot, especially when there is color correction and you add special effects.

Dec 04, 2012  Logically, the rendering is done via software running on the hardware, so what does this setting do? I would assume hardware would be the option you want if you have an amazing GPU, but doesn't the rendering get done on it anyways since the software (presumbly) uses the GPU? Or does it normally use the CPU, and the hardware setting uses the GPU? Mar 16, 2020  Before we move on to performance, let’s go over a few factors that you should consider when you’re stuck choosing between a Mac or PC. PC – The Cost. Apple isn’t known to be the most value-oriented company in the world and launching a $50,000 Mac Pro hasn’t helped their image. To help you determine which solution is right for you we have completed another 3D rendering software comparison of KeyShot vs V-Ray. The right 3D rendering software can help your design teams speed up time to market while reducing costs – so, you want the right solution to support your organization. KeyShot vs V-Ray: Feature and Benefit.

Introduction

V-Ray, from Chaos Group, is a widely used rendering engine for creating realistic 3D graphics. Two versions are currently available:

• V-Ray Adv, which uses the CPU and scales with both core count and clock speed
• V-Ray RT, which originally used CUDA to run calculations on NVIDIA GPUs but has been expanded recently to run on CPU cores as well

Chaos Group also publishes a benchmark utility for V-Ray, which can test both CPU and GPU performance. This is a fantastic utility for comparing different processors and video cards, and we run it here at Puget Systems on every workstation we build.

In this article, we are going to look at how Apple's desktop workstations compare to PCs in V-Ray. The V-Ray Benchmark is available for both Windows and macOS, and Macs have long been popular in content creation studios. Since all of the Macs currently available use AMD graphics cards, we will focus only on V-Ray Adv / CPU performance; NVIDIA GPUs are required for V-Ray RT.

Test Setup

To see how these different platforms compare in V-Ray, we ran V-Ray Benchmark 1.0.8 on three Mac workstations and two PC workstations. On the Mac side, we've got an older (but still being sold) Mac Pro with a 12-core CPU and two newer iMac Pros with 10- and 14-core processors; all of those use Intel Xeon chips. Novus camera software for mac windows 10. For the PC side, we wanted to have similar core counts included - so one workstation uses Core X series processors from Intel and was run with 10-, 14-, and 18-core chips installed. The other uses AMD's Ryzen Threadripper platform and was tested with 12- and 16-core CPUs.

Things like the video cards and SSDs varied a bit between the Mac and PC systems, but that should not impact V-Ray CPU scores. If you would like more details about the full hardware configurations we tested, click here to expand the following section.

Benchmark Results

Here are the results for the various systems we tested in V-Ray Benchmark 1.0.8:

Analysis

Apple's newer iMac Pro all-in-one workstations perform almost identically to the AMD Threadripper system we tested, but a little bit behind the Intel-based system with the same core counts. The 10-core iMac Pro is about 4% behind its PC counterpart, while the 14-core is approximately 10% slower. Since the CPUs here are built on the same technology (Xeon W and Core X both use the Skylake architecture) my suspicion is that the iMac Pro doesn't reach as high of all-core turbo speeds. That makes sense, given the limited space available for heatsinks or fans inside these all-in-one computers - and their remarkably quiet operation, even under load. We didn't have an 18-core iMac Pro to test, but I assume this trend would continue.

I hadn't mentioned the older Mac Pro yet because its performance in V-Ray is really poor. That is surely due to its use of a three-generation-old CPU and similarly old video card, so I cannot fault the hardware too much.. but I do think it is rather embarrassing that Apple is still selling such old hardware. They have said a newer Mac Pro desktop will be coming, in 2019 from what I have heard, but even when the current Mac Pro is finally retired this can still serve as a reminder to look under the hood of a computer before buying it. Someone purchasing one of these systems today, in 2018, is overpaying for a severely under-performing system.

Price Comparison

Speaking of overpaying, let's take a look at how much a full Puget-built PC workstation might cost - and compare that with what Apple charges for the iMac Pro (and the dated Mac Pro). To be fair here, we included a full kit of keyboard, mouse, monitor, and tech support that were selected to match or exceed the quality of what Apple bundles with their systems.

Here we have direct comparisons with both 14- and 10-core systems, and as you can see the Puget workstations are $600-1000 less expensive for similar specs and better performance. In fact, you could even get the top-performing Intel Core i9 7980XE 18-core and still pay less than what Apple charges for their 14-core design! And don't even get me started on the price tag of the older Mac Pro..

Conclusion

Apple's current crop of iMac Pro workstations aren't bad at rendering in V-Ray Adv, but you'll pay a lot more to get one than you would for a better-performing PC. Moreover, there are options on the PC side for even faster rendering speeds if you do want to pay more - just check out our look at the new Xeon Scalable processors in V-Ray. Going PC also opens up the option to use V-Ray RT, which doesn't work on the latest Mac desktops since they don't have any NVIDIA GPU options.
