Group 1 - Arm recently held the Arm UNLOCKED summit in Shanghai, where it officially launched the Arm Lumex Compute Subsystem (CSS) aimed at mobile devices [1] - Lumex CSS is essentially a marketing concept that includes Arm's new C1 series CPU architecture, G1 series GPU architecture, C1-DSU inter-core bus design, and other peripheral system IP designs [1][3] - It is important to note that Lumex CSS does not equate to a complete SoC architecture license, as it lacks essential components like NPU, baseband, power management, and ISP [3] Group 2 - The new product naming logic has undergone significant changes, with Arm introducing four new CPU IPs: C1-Ultra, C1-Premium, C1-Pro, and C1-Nano [8][11] - C1-Ultra is positioned as the flagship "super core," replacing the current Cortex-X925, while C1-Premium serves as the "next flagship big core" with similar architecture but smaller cache [11] - The performance and efficiency improvements of the new CPUs are notable, with C1-Ultra achieving a 25% increase in single-thread performance and a double-digit IPC performance growth compared to its predecessor [12][16] Group 3 - Arm also introduced the Mali G1 GPU IP family, which allows customization of shader core counts from 1 to 24, categorized into G1-Ultra, G1-Premium, and G1-Pro [13] - The new IPs generally show performance improvements, but there are concerns regarding power consumption, particularly with the G1-Ultra GPU, which has a 20% performance increase but a 9.2% rise in overall power consumption [22] Group 4 - The new architectures suggest that upcoming flagship mobile platforms will likely not use the C1-Nano "small core," with potential configurations including two C1-Ultra cores paired with six C1-Pro cores [23][25] - There is a concern that the performance improvements for the C1-Nano are not as significant as those for larger cores, which may lead to a decline in motivation for further development of small cores in the industry [29]
