Wouldn't just one GPU be enough to run the Sphere, or a I getting something wrong?
I remember hearing about that it's not exactly high resolution, each "pixel" being a bunch of pretty large lamps.
Wikipedia says it's 16,000x16,000 (which is way less than I thought). The way the math works, that's 16x as big as a 4k monitor, so 16 GPUs would make sense. And there's a screen inside and one outside, so double that. But I also can't figure out why it needs five times that. Redundancy? Poor optimization? I dunno.
But wouldn't that be only necessary if it needed to render real-time graphics at such a scale? If I'm correct, all its doing is playing back videos.
Even if it's just playing back videos, it still should compensate for the distortion of the spherical display. That's a "simple" 3d transformation, but with the amount of pixels, coordinating between the GPUs and some redundancy, it doesn't seem like an excessive amount of computing power. The whole thing is still an impressive excess though...
