ARM's in-progress fifth generation "Blackhawk" Cortex design is allegedly going through a troubled phase of development, according to Chinese insider sources. A Revegnus (@Tech_Reve) social media post highlights ongoing issues: "It's reported that the Cortex X5 architecture is underperforming compared to expectations. It's speculated that the high-frequency power consumption has surged explosively. Therefore, if performance is reduced for lower power consumption, the Geekbench 6 multi-core score of Dimensity 9400 may not achieve a score of 9,400 points." A recent Moor Insights & Strategy analysis piece proposed that "Blackhawk" would become "the most powerful option available at launch" later this year—mobile chipsets leveraging ARM's Cortex-X5 design are touted to face tough next-gen competition from Qualcomm and Apple corners.
