Where does the Vegas Lightsphere Ultra HD source come from?RTX A6000 Credits

The Sphere Giant Dome in Vegas is a familiar sight, not only does it feature 120 programmable LED light beads on the outside, but it also boasts a 16x16K ultra-high resolution LED dome giant screen inside. So how are these videos generated? The answer lies with NVIDIA.

According to the latest revelations, the videos were not rendered on-site, but rather in the Sphere Studios studio in California. As many as 150 RTX A6000 professional graphics cards were used in the production process, and were processed in three layers with a resolution of 16K and a frame rate of 60FPS.

The RTX A6000 graphics card still has the Ampere core architecture and is very powerful in terms of performance. It comes with 10,752 CUDA cores and 48GB of GDDR6 memory and is capable of outputting a maximum resolution of 7680×4320 on a single card, while the latest RTX 6000 ADA graphics card upgraded to the Ada Lovelace architecture also offers a significant boost in performance. It also comes with 18,176 CUDA cores and 48GB of GDDR6 memory, but costs only $88.

Official data shows that in order to support the Ultra HD resolution (6K), the Giant Orb uses a total of 27 compute nodes and transmits 4K video data through Hitachi Vantara software, which is then aggregated to 16K resolution. In addition, the system supports full 4:4:4 chroma downsampling technology with a display latency of only about 5 milliseconds. The entire system utilizes a large number of flash memory storage arrays, i.e., 4PB flash memory storage arrays, with transfer speeds up to 400GB/s.

In order to acquire the required 16K resolution sources, Sphere Entertainment has also developed its own camera, Big Sky, and can even capture up to 18K resolution.
