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.

Revegnus pulled in a rival SoC: "While Snapdragon 8 Gen 4 is seen to have minor issues, there is no evidence to support this claim. There might be a problem with low-frequency power consumption not showing clear superiority over ARM's middle cores." Qualcomm's next flagship model is performing admirably according to insiders—an engineering sample managed to score 10,628 points in alleged Geekbench 6 multi-core gauntlets. Late last month prototype clocks were leaked—Digital Chat Station claimed that a Snapdragon 8 Gen 4 High-Performance "Big" core was capable of reaching 4.0 GHz. Prior to the latest news, MediaTek's Dimensity 9400 SoC was observed achieving ~10,000 multi-core Geekbench 6 scores—leaked CPU cluster details present a single "Big" Cortex-X5 unit operating alongside three Cortex-X4 cores.
