"ARM has unveiled its next generation CPU and GPU designs and is doing some rebranding at the same time - meet the ARM C1 CPUs and G1 GPUs, which will form the ARM Lumex compute subsystem (CSS). "Lumex" is the new branding that ARM will use for mobile-focused designs (for others, "Niva" will be used for PC, "Zena" for automotive and so on)."
"The new C1 cores are the first to be built on the ARMv9.3 architecture. All of them support ARM's Scalable Matrix Extension 2 (SME2), which accelerates AI workloads, but also improves more routine stuff - e.g. decoding HDR video is 10% more efficient with SME2. The ARM C1-Ultra is focused on increasing Instructions Per Cycle (IPC). In single-threaded tasks, the C1-Ultra is up to 25% faster than the Cortex-X925."
"ARM also introduces a new tier of CPU core, the ARM C1-Premium. This one is aimed at sub-flagship designs - it has 35% smaller surface area than the Ultra (meaning that chips with it will be cheaper), which gives it the best-in-class area efficiency (i.e. performance per mm² of silicon). The ARM C1-Pro core will be used for sustained workloads in high performance chips and as the big core for mid-range designs."
ARM introduced the Lumex-branded mobile compute subsystem featuring C1 CPU cores and G1 GPUs. The C1 family is built on ARMv9.3 and adds Scalable Matrix Extension 2 (SME2) to accelerate AI workloads and improve routine tasks such as HDR video decoding. The C1-Ultra targets maximum IPC with up to 25% single-thread gains versus the Cortex-X925. The new C1-Premium delivers 35% smaller die area than Ultra for superior area efficiency and lower cost. The C1-Pro targets sustained high-performance and mid-range big-core roles. The C1-Nano focuses primarily on power efficiency.
