Overview
- The Lumex lineup introduces four ARMv9.3-A core tiers—C1-Ultra, C1-Premium, C1-Pro, and C1-Nano—to let licensees tailor performance and power more precisely.
- Arm cites targets up to 4.1 GHz for C1-Ultra on 3 nm (3.5/2.5/2.0 GHz for Premium/Pro/Nano) and claims versus last year of +25% single-thread, +45% multi-thread, +16% gaming, and 28% lower power at equal performance.
- An optional SME2 matrix engine aims to accelerate CPU AI by about 3.7× on average, with examples including faster Whisper transcription, Gemma 3 encoding at 398 vs 84 tokens per second, and Stable Audio generation in 9.7 vs 27 seconds; Arm continues to omit a built-in NPU though partners can add one.
- Graphics return to the Mali name with G1-Pro, G1-Premium, and G1-Ultra, and the Ultra adds RTUv2 ray-tracing units per core for up to 2× ray-tracing performance and a reported 104% gain in speech AI versus Immortalis-G925.
- Arm’s reference design pairs 2× C1-Ultra with 6× C1-Pro and supports up to 14 CPU cores, and partner SoCs are expected later this year as Arm also teases a separate PC-focused Niva core with details to come.
