.jayderyu said: Ding. I was right. Look at the schematics. GPU 1, GPU 2. Graphical Processing Unit. I figured Nintendo would be cheap and run a second GPU to get the 3d output at proper speads rather than wasting money and time with single GPU processing.
Nintendo is not using Tegra, Seriously Nintendo using a highend NVidia tech? Nintendo uses cheap graphical chip for the DS/i. All they are going to do is add a second one. I already posted my theoritcal sutrcture for getting 3d onto the phillips/panasoic? 3d screen and this seems to indicate I was right.
So to Zarx, no it's not strange. It's logical and falls into the realm of common sense. Why double the speed of a single GPU to provide 2 renders. This would create an exponential cost for every X% increase. It would come to the point where the chip would be 5x the current chip for only double the power. Where as just some tweaking you could pay only for 1 extra chip and VRAM and get the same performace? what in any logical mind where paying an exponential cost for lowered returns is better that 2 chips. Also keep in mind that parralel processing is better than singular processing. In the case of a single GPU you still need to render frame 1 then frame 2. In parrallel you process both frames at the same time. |
I never said it was bad or strange that they would use two GPUs instead of a single tegra chip (unless we are talking power usage) I just found it interesting after all the rumors about Nintendo using a Nvidia chip. The tegra line of chips is actually a system on a chip design that is quite scalable, usually it does include Nvidia GPU components and 1 or 2 ARM cores with a bunch of controllers for Memory management, Wifi, I/O, Image processing (for cameras,) Video decoding etc, the last rumor that I read about it suggested that Nintendo were just licensing the tech to create a custom CPU rather than a standard Tegra CPU, so they could still be using a tegra derived chip and two other GPUs. Or the two GPUs could be both tegras with just the GPU components. The Tegra line is actually used in a quite a few of mobile devices that vary from things like like the Zune HD and many android phones to many up coming tablet PCs (not the iPad) and like I said is very scalable from high to low end.
