Microsoft Surface Laptop Ultra Engineering Unit Features NVIDIA RTX Spark Arm SoC with 20 CPU Cores and 6144
An unreleased Microsoft Surface Laptop Ultra engineering unit has been exposed, powered by an NVIDIA RTX Spark Arm SoC with 20 CPU cores and 6144 GPU cores. Under an 80W PL1 power limit, it scored 1386 points in Cinebench 2024 multi-core and 123 points single-core, underperforming the Apple M5 Pro and some x86 platforms. The device suffers from early prototype issues including regular crashes every hour, high temperatures (CPU up to 100°C, GPU 90°C), and increased standby power after a driver update. GPU performance remains consistent on battery and plugged in.
