Draft:ARM Cortex-X925

The ARM Cortex-X925 is a high-performance CPU core from Arm, released in 2024 as part of Arm's "total compute solution." It serves as the successor of ARM Cortex-X4. X-series CPU cores generally focus on high performance, and can be grouped with other ARM cores, such as ARM Cortex-A725 or/and ARM Cortex-A520 in a System-on-Chip (SoC).
