So think about what kinds of scenes you make first. The more geometry you have in your scene, the larger the performance gap will get between different GPUs. The general idea is that RT cores work better with more geometry. RT cores enhance render speed, but how much they enhance render speed can vary wildly from scene to scene. The wild card with Iray is the Ray Tracing core. Everybody is going to have a different answer depending on much they personally value rendering times. The question is if it is worth that much to you to upgrade. Whether it be a 4090ti or the 5000 series later on. Even if you weren't to get it, I would imagine there might be some price reduction in the regular 4090 at that point.Īs for running both, if your PSU and your circuit breaker can handle it, go for it. If you can afford to wait, I'd wait for the 4090TI to drop. Sounds wonderful!! will you consider 4090ti? seems to come out soon, I'm thinking about get 4090 now or wait for 4090ti.Īnd maybe build a 3090+ 4090 both to render, I've seen someone done it and the result are amazing (another 50% boost), but the power and heat might be a problem if long time using? But I would consider it a good piece of equipment if you can afford it.
If I add a lot of refractive surfaces and geoshells it still goes up to the 15 - 20 minute mark. I was finding on the 3090 it was taking 16 to 20 minutes to render. Most multi subdivided figures + room and props scenes render in 7 - 9 minutes. The 4090 is faster, 40-50% faster in general.
