Benchmark Results

I ran the same YOLOv8-medium model (object detection, 640×640 input) across all three:

                     FPS (INT8)   Latency    Power     FPS/Watt
Jetson Orin Nano      142         7.0ms      15W       9.5
Intel Core Ultra      68          14.7ms     12W       5.7
Apple M4 (Neural)     95          10.5ms     8W        11.9
Apple M4 (GPU)        125         8.0ms      15W       8.3

For LLM inference (Llama 3.2 3B, INT4):

                     Tokens/sec   First Token   RAM Used
Jetson Orin (8GB)     18           890ms         6.2GB
Intel Ultra (32GB)    22           650ms         4.8GB
Apple M4 (24GB)       35           420ms         5.1GB

When to Use What

Choose Jetson Orin When:

• You need dedicated edge devices (not laptops)
• Running computer vision workloads (CUDA ecosystem is unmatched)
• Deploying in industrial/outdoor environments (fanless, -25°C to 80°C)
• Your team knows NVIDIA tooling (TensorRT, DeepStream, Triton)

Choose Intel NPU When:

• Edge deployment means office laptops/desktops
• Running background AI tasks (copilots, document processing, voice)
• You need x86 compatibility for existing software
• Budget is tight — NPU comes free with the CPU

Choose Apple Silicon When:

• Deploying on Mac fleet (design studios, dev teams)
• LLM inference is the primary workload (unified memory wins)
• Power efficiency is critical (battery-powered scenarios)
• You want the best developer experience (Core ML is polished)

The Deployment Reality

Hardware benchmarks don’t tell the full story. Here’s what matters in production:

Software ecosystem matters more than raw TOPS. Jetson’s CUDA support means every ML framework works out of the box. Intel’s OpenVINO is catching up but has gaps. Apple’s Core ML requires model conversion that sometimes loses accuracy.

Memory architecture is the bottleneck. Jetson’s 8GB shared RAM limits model size. You can’t run a 7B parameter model. Intel and Apple systems with 32GB+ can. For LLMs at the edge, memory > compute.

Thermal management is underrated. Jetson handles 40°C ambient. A MacBook throttles at 35°C ambient under sustained load. Intel laptops vary wildly by manufacturer.

My Recommendation Matrix

Use case                          → Hardware
Factory vision inspection         → Jetson Orin
Retail analytics                  → Jetson Orin
Office document AI                → Intel NPU laptop
Developer AI assistant            → Apple M4
Edge LLM (private)                → Apple M4 (24GB+)
Outdoor/harsh environment         → Jetson Orin (industrial)
Fleet of 100+ identical devices   → Jetson Orin

The right answer depends on your workload, environment, and team skills. But if I had to pick one for general edge AI? Jetson Orin for dedicated devices, Apple M4 for anything that needs a screen.
