Orin 系列不同型号的 理论算力（峰值性能） 由硬件配置决定（需结合具体型号）：

型号 CUDA 核心数 Tensor Core 数 AI 算力（INT8） FP32 算力（TFLOPS）
Jetson AGX Orin 2048 64 275 TOPS 2.66 (1.3 GHz 频率下)
Jetson Orin NX 512 16 100 TOPS 0.67 (1.173 GHz 频率下)
Jetson Orin Nano 384 * 无 40 TOPS 0.39 (1.02 GHz 频率下)

该芯片基于 ARMv8-A Cortex-A72 架构，具备 64 位处理、多核并行、硬件加速（NEON / 加密）、高能效比 等特性，适合中高性能、低功耗场景，但受限于架构发布时间，在前沿计算任务（如高端 AI、复杂科学计算）上略逊于现代 ARM 架构。
