GLBPowered by 150 NVIDIA GPUs: The Stunning 16K Visuals of Las Vegas Sphere
0Article by Filip Radivojevic
Las Vegas, a city renowned for its dazzling lights and entertainment, has recently added a new marvel to its skyline: The Sphere. This architectural and technological wonder, located at The Venetian resort, has captivated the world with its impressive visual displays and cutting-edge technology.

A Technological Powerhouse
The Spheres visual spectacle is powered by a staggering 150 NVIDIA RTX A6000 GPUs. These high-performance graphics cards drive the massive 16x16K displays inside the Sphere, covering an area of 160,000 square feet. Additionally, the exterior boasts 1.2 million programmable LED pucks across 580,000 square feet, making it the world's largest LED screen.
NVIDIA's involvement in this project showcases the immense capabilities of their technology. According to NVIDIA's blog, the RTX A6000 GPUs are responsible for rendering content in real-time, ensuring seamless and synchronized imagery across the Sphere's vast displays. The GPUs are supported by NVIDIA's BlueField data processing units (DPUs) and ConnectX-6 Dx network interface cards (NICs), which together deliver robust network connectivity and media streaming capabilities.
Unprecedented Visual Quality
The Sphere's interior screen is a marvel in itself, described as a three-layered 16x16K display. This means that each pixel is powered by three individual LEDs, significantly enhancing brightness and power efficiency. This triple-layer configuration allows the display to achieve a maximum of 60 frames per second with minimal latency, ensuring a smooth and immersive visual experience.
Externally, the Sphere is equally impressive. The 1.2 million LED pucks, each containing 48 individual diodes, create a dynamic and vibrant display capable of showing anything from advertisements to elaborate light shows. This exterior screen can transform the Sphere into a giant canvas, displaying breathtaking visuals that can be seen from miles away.
The Heart of Content Creation
The content displayed on the Sphere is crafted at Sphere Studios in Burbank, California. This facility is equipped with NVIDIA A40 data center GPUs, which handle the intensive computational tasks required for creating high-resolution content. Sphere Studios even has a quarter-scale replica of the Sphere's interior for testing purposes, ensuring that the visuals look perfect before they are displayed on the full-scale Sphere.
One of the most remarkable pieces of technology used at Sphere Studios is the Big Sky camera system. Developed in collaboration with Deanan DaSilva, former CTO of Red Digital Cinema, this camera captures uncompressed 18K images at 120 frames per second. The camera's enormous 77.5mm x 75.6mm sensor and bespoke fisheye lens allow it to fill a 32TB storage card in just 17 minutes at 60fps, necessitating custom solutions for data transfer and storage.

The Cost of Innovation
While the Sphere is an incredible feat of technology and design, it comes at a significant cost. Each NVIDIA RTX A6000 GPU used in the Sphere's setup costs around $4,500, and the entire system's electricity consumption is estimated to be enough to power 21,000 homes during peak usage . Despite these high costs, the Sphere has proven to be a valuable addition to Las Vegas, drawing thousands of visitors and generating substantial revenue for the city.
A New Era of Entertainment
The Sphere represents a new era in entertainment and architectural design. Its unmatched visual experience, made possible by NVIDIA's cutting-edge technology, offers a glimpse into the future of large-scale displays. From concerts and special events to breathtaking light shows, the Sphere provides an immersive experience that leaves a lasting impression on all who see it.
For those interested in learning more about the technology behind the Sphere, NVIDIA's blog post offers an in-depth look at the components and processes involved in bringing this architectural wonder to life.
In conclusion, the Sphere in Las Vegas is more than just a giant screen; it is a testament to human ingenuity and technological advancement. As it continues to captivate audiences and push the boundaries of what is possible, the Sphere stands as a shining example of what can be achieved when art and technology come together.
