The decision to employ older Cortex-X925 and Cortex-A725 cores on the RTX Spark to form a 20-core CPU configuration will probably haunt NVIDIA because a new Cinebench 2026 leak reveals that the chipset produces subpar multi-core results, despite Microsoft’s Surface Laptop Ultra housing the SoC set to the ‘High Performance’ profile. Fortunately, the RTX Spark manages to retain some dignity in the single-core benchmark. High Performance mode on Surface Laptop Ultra isn’t enabled by default, but hidden configuration allows RTX Spark’s Cortex cores to pull nearly 50W in new test We’ve previously reported that the altered Cortex-X925 cores running RTX Spark were […]
