MediaTek's New SoC for Googlebooks

MediaTek has unveiled the Dimensity CX C10 Max processor, which will be integrated into Google's upcoming "Googlebook" flagship laptops. This marks the debut of MediaTek's Dimensity CX lineup, positioning it between the RTX Spark and Kompanio chips in their product portfolio.

The C10 Max is fabricated on a 3nm node (TSMC N3) and incorporates an all-performance-core design, featuring eight CPU cores, eleven GPU cores, and MediaTek's NPU 890, which delivers up to 55 TOPS of AI performance. The processor will launch concurrently with Googlebooks on September 21.

Core Configuration and Architecture

The CPU configuration of the Dimensity CX C10 Max includes one Cortex-X925 core, three Cortex-X4 cores, and four Cortex-A720 cores. The Cortex-X925 is an upgrade to the Cortex-X4, offering higher clock speeds and a larger L2 cache. This specific core arrangement mirrors that found in MediaTek's Dimensity 9400, 9400+, and 9500s mobile chips.

Similarities to Kompanio Ultra 910

Despite being presented as a new flagship, the Dimensity CX C10 Max shares significant architectural similarities with MediaTek's previous Kompanio Ultra 910. It features the same Arm Immortalis-G925 MC11 GPU and MediaTek NPU 890. Both chips also include 12MB of L3 cache and 10MB of system-level cache.

The primary distinction identified in the shared specifications is an increase in memory speed. While both utilize LPDDR5X, the C10 Max supports speeds up to 9,600MT/s, an increase from the Kompanio Ultra 910's 8,533MT/s.

Performance Claims

MediaTek has made general performance claims for the C10 Max, stating up to 15% faster multi-threaded performance and 50% lower power consumption in single-threaded workloads. These claims are made without specific comparative benchmarks against the Snapdragon X Elite X1E-84-100.
