RenderingHey, guys. Here's a question I'm hoping you guys know. If I want to shorten the time it takes for me to render video, is the CPU more important or the graphic card? And how about when rendering computer animation? Is the CPU more important or the graphic card? Thanks. Paul Here's a question I'm hoping you guys know. If I want to shorten the time it takes for me to render video, is the CPU more important or the graphic card? CPU And how about when rendering computer animation? Is the CPU more important or the graphic card? Both . . . depending on what kind of animation and what software you use. Chieh Cheng Cool...thanks. I figured that video would be CPU only but I want to be certain. For graphics, someone was tell me that some companies use server farms to do their work for them. Which means mostly CPU. So, is GPU like a CPU but with only functions to do math for rendering purposes? How do I tell if what software I have is depended on the GPU or not? I have Vue 5. Maybe I should ask the tech support about it. I'm asking because I want to know if it's necessary I get a laptop with a good GPU or not. Paul For graphics, someone was tell me that some companies use server farms to do their work for them. Which means mostly CPU. So, is GPU like a CPU but with only functions to do math for rendering purposes? It could be a server farm of CPU. Or a server farm of GPU. Or a server farm of both. Or a server farm of no CPU nor GPU, but rather a server farm of modems. Point is a server farm doesn't tip the scale in one way or another unless quantified. How do I tell if what software I have is depended on the GPU or not? I have Vue 5. Maybe I should ask the tech support about it. I'm asking because I want to know if it's necessary I get a laptop with a good GPU or not. It's a matter of speed. How fast do you want to render images. You can render images with zero GPU, do everything in software on the CPU. It would be extremely slow, but still possible. When I was playing with POV on my 386 and doing full software rendering, it would take 8 hours. I left my computer over night to render one image. I looked at the entry level Vue 5. It uses OpenGL. So if you have a GPU with hardware OpenGL support, it would be useful. Otherwise you default to software rendering on the CPU. Chieh Cheng Okay...I think he was talking about a farm for rendering animations. As for OpenGL suport, that really narrows down my choices. Thanks. Paul I know. The concept still applies. If they need more CPU horsepower, they would have a server farm of CPU's. If they need more GPU horsepower, they would have a server farm of GPU's. It all depends on what they are rendering and what software they use. Chieh Cheng Hmmm...I see...so, let's narrow this down to 3D animation rendering...and that it can use CPU and/or GPU...now, I'm at my workstation and I sent off my work for a 15 minutes worth of animation to a farm. This farm of computers would also need to have a server version of that same software, right? I've always wonder how computers in a farm or cluster talk to each other. Paul Let's narrow this down even more, because when you talk about specifics, you have to be specific. You have a 2 hour 3D animation that you want to produce. To render this animation on a computer with OpenGL GPU using Vue 5 takes a month. You have a budget for four computers. Each would have one OpenGL GPU and one copy of Vue 5. How long is your animation going to take to render using this non-clustered solution? One week: You would render 30 minutes of 3D animation on each computer in parallel. Chieh Cheng I see...then you would have to put them together into one movie, right? By the way, are the time you came up with below hypothetical numbers or are they real world numbers? Paul It all depends on the software. I don't know how Vue 5 works. I pulled the numbers out of the air. Chieh Cheng Oh, I see...cool...thanks. Paul >> Here's a question I'm hoping you > CPU >> And how about when rendering > Both . . . depending on what kind of Agreed. You can also check your task manager performance (Windows) to see if memory is maxed out or cpu is maxed out when you are running that process. If one of those (or both) are maxed, then a faster cpu and more memory will help. Sp Chess lAST NIGHT, I trying out some unscientific benchmarks on rendering with Vue 5. I think the best chips out there could still be AMD dispite Intel's latest effort. And boy, does a good graphic card matter....go, AMD, with your 4x4! Now, I know why studios spend about 15-20K per workstation. Even the best stuff out there took 4-5 minutes to render one computer generated picture of a scenic mountain side. Paul
