Tegra X1: The Powerful Processor Behind SHIELD

by Brian Choi

Tegra X1 is the most advanced mobile processor we’ve ever created, and it’s at the heart of the NVIDIA SHIELD Android TV experience. It enables SHIELD to deliver performance that’s 13x better than Apple TV (2015), 3x better than Roku 4, and 8x better than Fire TV (2015).


Built on the powerful NVIDIA Maxwell architecture, Tegra X1 has 256 GPU cores, a 64-bit CPU, unbeatable 4K video capabilities, and more power-efficient performance than its predecessor.

Faster Than ASCI RED: The Previous Top Supercomputer

Tegra X1 has more horsepower than the fastest supercomputer of 15 years ago, ASCI Red, which was the world’s first teraflops system. ASCI Red occupied 1,600 square feet and consumed 500,000 watts of power — with another 500,000 watts needed to cool the room it occupied.

By comparison, Tegra X1 is the size of a thumbnail and draws under 10 watts of power.

As serious gamers know from using the NVIDIA GeForce GTX 980 graphics card, the Maxwell architecture solves some of the most complex lighting and graphics challenges in visual computing. Its innovations include Voxel Global Illumination, or VXGI, for real-time dynamic global illumination, and Multi-Frame Anti-Aliasing, or MFAA, for incredibly lifelike graphics in the most demanding games and apps.

Tegra X1 Technical Specifications

Tegra X1 supports all major graphics standards:

  • Unreal Engine 4
  • DirectX 12
  • OpenGL 4.5
