ARM-based platforms are specifically designed for edge deployments. For instance, the Jetson Xavier NX processes 720p video at approximately 20.1 FPS, while the Jetson Nano achieves 16 FPS using FP16 precision. Non-NVIDIA solutions, like Meta's EgoBlur, operate on standard CPUs and generic GPUs, managing around 2 FPS for Full HD images. Tamas Foldi from HCLTech-Starschema highlighted the difference in performance, stating:

"NVIDIA LPDNet was able to detect LPs from low-res, low-quality feeds... LPDNet wins by orders of magnitude [in inference speed]".

These performance gaps directly impact both cost-effectiveness and the complexity of system integration.

Cost and ROI

Intel offers cost-efficient options for AI workloads. For example, the Intel Gaudi series provides strong AI performance. For retrofitting existing setups, the Intel Neural Compute Stick 2 is a budget-friendly, plug-and-play solution that adds AI capabilities without requiring a full system upgrade.

ARM-based accelerators shine in power efficiency. The Hailo-8 chip delivers 26 TOPS while consuming just 2.5 watts, translating to about 10 TOPS per watt. Similarly, Google Coral achieves 4 TOPS at 2 watts, making it a great fit for low-power IoT applications.

Ease of Integration

Intel simplifies integration with tools like the OpenVINO toolkit and the Neural Compute Stick 2, which connects via USB for quick deployment. Solutions like Meta's EgoBlur, using standard Python/Conda environments, also make initial setups on generic hardware straightforward.

However, these platforms often lack the cohesive software ecosystem that NVIDIA provides through tools like DeepStream and TAO Toolkit. While the openness of Intel and ARM platforms can simplify basic setups, it often requires more custom development for optimized multi-stream processing. This additional effort can affect scalability and deployment timelines.

Scalability

Beyond performance and cost, scalability plays a key role in selecting a hardware platform. Intel CPUs scale by distributing workloads across multiple cores rather than relying on massive parallelization. For centralized deployments, Intel Xeon processors can handle over 100 FPS for 720p streams, making them suitable for moderate-scale installations. Typically, systems add video streams until CPU utilization approaches 90-95%.

ARM-based platforms, on the other hand, focus on edge scalability. Numerous low-power devices process data locally, which works well for distributed setups like smart city applications. However, achieving the throughput of a single high-end NVIDIA GPU often requires deploying more hardware units. Emerging competitors, such as Intel's Gaudi 3 and Google TPUs, are also stepping into the enterprise space as alternatives to NVIDIA's architecture for large-scale workloads.
