Ideally I would like an Nvidia RTX 3090 GPU and at least 64GB of RAM.

<.I am in the process of sorting out a second computer that I can use specifically for high end rendering tasks using Daz Studio Iray and Blender. Otherwise your options are exporting to Blender and using Blender Cycles to render. It is a great resource for making purchase decisions for Iray. There are all kinds of benchmarks across Nvidia hardware, and even some CPUs are on there. You can always check out the Iray benchmark thread to get an idea of how different hardware stacks up.

Even modest GPUs from two generations ago are still faster than the newest and most expensive desktop CPUs when it comes to rendering Iray. But Iray is designed around GPUs, and it horribly slow on even the fastest CPUs. Iray's CPU fallback is thanks to Intel Embree. Daz Iray is actually a bit of an exception, in fact other Iray plugins (outside of Daz) may not have a CPU fallback mode. CUDA is quite popular in the 3D world, so you will see it used in a lot of programs. Most CUDA based render engines do not even offer a CPU rendering mode. If they are based on CUDA then you will need a Nvidia GPU. If you see other render engines out there pay attention to if they are based on CUDA or not. Of course this would require patience and time. Then when the GPU market finally dies down you can use that to buy a pretty decent Nvidia GPU for Iray. With the market the way that it is, you might even make money on such a transaction. It is extremely important to do some research before making such purchase decisions.īut you can at least sell you AMD GPU right now and get a lot back for it.
