RTX Spark tested in Surface Laptop Ultra: strong local AI, weak gaming

Tom's Hardware tested Nvidia's RTX Spark platform in a top-end Surface Laptop Ultra with 20 CPU cores, 6144 CUDA cores and 128GB of LPDDR5X-9400. It beat a MacBook Pro with M5 Max by about 25% in local AI tasks, but its Arm CPU trails Apple's M5 Max in Geekbench and gaming is not its strength.

• Surface Laptop Ultra: 20 CPU cores, 6144 CUDA cores, 128GB LPDDR5X-9400
• RTX Spark finishes AgentPerf-local with Qwen 3.8 27B ~25% faster than M5 Max MacBook Pro
• Arm CPU complex trails Apple M5 Max in single- and multi-core Geekbench
• Platform targets local AI agents rather than gaming
