RTX Spark Windows laptops beat MacBook Pro M5 Pro in PT benchmarks

Principled Technologies says three Windows 11 Pro laptops with NVIDIA RTX Spark N1X outperformed a 16-inch MacBook Pro with M5 Pro in AI, gaming and 3D tests. The report highlights faster AI generation, quicker local LLM response and near-parity battery performance for the Windows systems.

Why it matters: - Principled Technologies’ benchmark report suggests Windows laptops with NVIDIA RTX Spark could be a stronger fit than a MacBook Pro with M5 Pro for creators, gamers and professionals who run AI models locally. - The tests point to faster AI generation, better gaming frame rates and stronger real-time 3D performance on the Windows systems. - The report also found that the Windows laptops held close to their plugged-in performance when running on battery, which matters for mobile workflows.

What happened: - Principled Technologies tested three Windows 11 Pro laptops with NVIDIA RTX Spark N1X: the Microsoft Surface Laptop Ultra, HP OmniBook Ultra Laptop and ASUS ProArt P16. - PT compared those systems with a 16-inch Apple MacBook Pro with Apple M5 Pro running macOS Tahoe. - All four systems had 64 GB of unified memory. - PT used pre-production units, so retail performance may vary. - The report says Windows laptops with NVIDIA RTX Spark generated AI video up to 5.7x faster than the MacBook Pro with M5 Pro. - PT also says the Windows laptops reached the first token up to 2.1x faster in llama.cpp testing on the Qwen3.5 27B model.

The details: - In the ComfyUI FLUX 2-KLEIN-4B-T2I-BASE benchmark, the Surface Laptop Ultra generated AI images up to 4.3x faster than the MacBook Pro with M5 Pro. - In the ComfyUI LTX-2.3-T2V benchmark, the Windows laptops generated AI video up to 5.7x faster than the MacBook Pro. - The Surface Laptop Ultra reached up to 5.4x faster AI video generation in that test. - In llama-bench with an 8,192-token prompt, the Windows laptops reached the first token up to 2.1x faster than the MacBook Pro. - The Surface Laptop Ultra delivered up to 44% more frames per second in the Cyberpunk 2077 built-in benchmark. - With NVIDIA DLSS Frame Generation, the Windows laptops rendered real-time 3D in the Unreal Engine 5 Editor at up to 5.1x more frames per second. - PT used the City Sample project for the Unreal Engine 5 Editor workload. - PT also tested Blender on the Windows laptops both plugged in and on battery. - The Windows laptops delivered within 3% of their plugged-in performance in Blender and llama.cpp testing when running on battery.

Between the lines: - The results favor a Windows/NVIDIA workflow for buyers prioritizing local AI speed and real-time graphics performance over the MacBook Pro’s platform. - Because the systems were pre-production units, the gap could shift once retail hardware ships. - The test mix also suggests PT is positioning RTX Spark laptops as all-around creator machines, not just AI-focused systems.

What's next: - PT directs readers to the full report, Benchmark testing: Windows PCs powered by NVIDIA RTX Spark. - Buyers will likely watch for retail availability and independent testing to see whether the benchmark results hold outside PT’s lab. - Principled Technologies says it is based in Durham, North Carolina, and offers fact-based marketing and competitive analysis backed by transparent methodologies.
