Jetson Xavier NX System-on-Module

Volta GPU + Carmel CPU + 8GB LPDDR4x + 16GB eMMC 5.1

1.0 Functional Overview

NVIDIA® Jetson Xavier™ NX brings AI supercomputer performance to the edge in a compact system-on-module (SOM) that’s

smaller than a credit card. Jetson Xavier NX is built around a low-power version of the NVIDIA Xavier SoC, combining the

NVIDIA Volta™ GPU architecture with 64-bit operating capability, integrated advanced multi-function video and image

processing, and NVIDIA Deep Learning Accelerators.

Compute performance up to 14 TOPS (at 10W) or 21 TOPS (at 15W) enables the Jetson Xavier NX to run multiple neural

networks in parallel and process data from multiple high-resolution sensors simultaneously. It also offers a unique combination

of performance and power advantages with a rich set of I/Os, from high-speed CSI and PCIe to low-speed I

Cs and GPIOs,

allowing embedded and edge computing devices that demand increased performance but are constrained by size, weight, and

power budgets.

Volta GPU

The Graphics Processing Cluster (GPC) is a dedicated hardware block for computing, rasterization, shading, and texturing of

most of the GPU’s core graphics functions. The GPC is comprised of Texture Processing Clusters (TPC), with each TPC

containing two Streaming Multiprocessor (SM) units, and a Raster Engine. The SM unit creates, manages, schedules, and

executes instructions from many threads in parallel. Raster operators (ROPs) continue to be aligned with L2 cache slices and

memory controllers. The SM geometry and pixel processing performance make it highly suitable for rendering advanced user

interfaces, while the efficiency of the Volta GPU enables this performance on devices with power-limited environments.

Each SM is partitioned into four separate processing blocks (referred to as SMPs), each SMP contains its own instruction

buffer, scheduler, CUDA cores, and Tensor cores. Inside each SMP, CUDA cores perform pixel/vertex/geometry shading and

physics/compute calculations, and each Tensor core provides a 4x4x4 matrix processing array to perform mixed-precision

fused multiply-add (FMA) mathematical operations. Texture units perform texture filtering and load/store units fetch and save

data to memory. Special Function Units (SFUs) handle transcendental and graphics interpolation instructions. Finally, the

PolyMorph Engine handles vertex fetch, tessellation, viewport transform, attribute setup, and stream output.

Features:

• End-to-end lossless compression

• Tile Caching

• Support for OpenGL 4.6, OpenGL ES 3.2, Vulkan 1.1

• Adaptive Scalable Texture Compression (ASTC) LDR profile supported

• CUDA support

• Iterated blend, ROP OpenGL-ES blend modes

• 2D BLIT from 3D class avoids channel switch

• 2D color compression

• Constant color render SM bypass

• 2x, 4x, 8x MSAA with color and Z compression

• Non-power of 2D and 3D textures, FP16 texture filtering

• FP16 shader support

• Geometry and Vertex attribute instancing

• Parallel pixel processing

• Early-z reject: Fast rejection of occluded pixels acts as multiplier on pixel shader and texture performance while

saving power and bandwidth

• Video protection region

• Power saving: Multiple levels of clock gating for linear scaling of power
