Recently, we talked about some technical specifications of the huge spherical LED screen Sphere in Las Vegas. And now Nvidia has shared additional information about the hardware graphics resources that provide image output to the high-resolution giant screen.
The area of the Sphere is 580,000 square feet (53,884 m2), with the interior area being 160,000 square feet (14,865 m2). Both the internal and external screens support video output at 16K resolution. Each relies on a set of 27 nodes, each of which provides 4K streaming through Hitachi Vantara software.
Nvidia characterizes the display as 16x16K. The interior screen is described as three-layered, which likely means that three LEDs form each pixel of the screen. Such multilayer displays increase pixel brightness, significantly saving electricity, which is a significant requirement for a screen covering nearly 4 acres. A three-layer 16K screen can display information at a maximum speed of 60 frames per second with a delay of 5ms or less.
The screen contains 1.2 million programmable LED points, each containing 48 individual diodes. They all work together to form the necessary image. Server computers based on 150 Nvidia RTX A6000 accelerators are used to process graphic information. The infrastructure and software for these servers are provided by the Hitachi Vantara division. All 27 nodes used in Sphere contain 4 PB (1 PB = 1024 TB) of flash memory with a data transfer rate of 400 GB/s.
Nvidia and Hitachi Vantara take responsibility for connecting the display nodes of Sphere to the network, equipment, and connecting Sphere to Sphere Studios in Burbank, California, where content for Sphere is created.
Sphere Studios in Burbank has a quarter-scale interior of the Sphere for testing purposes. The content creation studio uses Nvidia A40 data processing center graphic processors. The creative process also uses the Big Sky camera system, which captures uncompressed 18K images at 120 fps on a sensor with dimensions of 77.5×75.6 mm and individual "fish-eye" lenses. The Big Sky camera fills a 32 TB storage in 17 minutes when recording at 60 fps and achieves a data transfer rate of 60 GB/s when unloading images to external storage devices.
