I know this would be more suitable for the official Chaos V-Ray forum however a product license is required in order to be able to post there and right now I do not have acces to one. Here are some of my questions: 1) Does CPU come into play when it comes to V-Ray GPU rendering ? 2) Is 3Ds Max or V-Ray able to properly take advantage of PCIe 5.0 or PCIe 4.0 for that matter ? Does it improve render speed when using multiple GPUs ? Or is it that PCIe 3.0 is fast enough for V-Ray as it is and newer PCIe standards only improve in the disk read-write speeds? 3) Considering that the i9 12900KS has only 20 PCIe lanes that can work at best in a 1x16+4 or 2x8+4 PCIe 5.0 configuration, would it be better to use a i9 10980XE with 48 PCIe lanes that supports 2x16 but on PCIE 3.0 or a Ryzen 5950x that has 20 PCIe lanes (1x16+4 or 2x8+4 PCIe) on PCIe 4.0 ? Apart from 2x16 PCIe 5.0 which is only available on Threadripper, Epyc or Xeon which configuration would provide maximum performance for GPU rendering in V-Ray ? For this I was hoping that I could get away with an intel i9-12900K since workstation CPUs are exponentially more expensive than regular consummer processors. Since this is going to be very expensive I need it to be as futureproof as possible which means that I aim to have a DDR5 and PCIe 5.0 compatible build. This workstation will use the GPUs for rendering henceforth CPU rendering performance is not critical, the main concern when it comes to choosing a CPU is enabling the best connectivity and maximum speed and bandwith. Even though I know that nVidia RTX 4000 series is coming soon, unfortunately I can't wait for it since the company needs this workstation now so that deadlines can be met. This build will have 2 GPUs since the current build that runs only one GPU it's not fast enough for our needs.
My company tasked me with building a workstation for 3D modelling and rendering of assets using the integrated V-Ray renderer inside 3Ds Max.
