MediaTek is taking its Dimensity brand beyond smartphones and tablets with the new Dimensity CX C10 Max, the flagship processor in its newly introduced Dimensity CX computing family. Announced on September 21, the chip is designed for the emerging Googlebook category and combines an all-big-core CPU, an 11-core GPU and a 55 TOPS NPU on a 3nm-class platform.
The move gives MediaTek a new position in personal computing, with the company focusing on the combination of performance, power efficiency and local AI rather than simply adapting its mobile silicon for laptops.
What Is the Dimensity CX C10 Max?
The C10 Max is the first product in MediaTek’s new Dimensity CX, or Compute Experiences, family. MediaTek describes CX as its processor line for the next generation of personal computing, with CPU, GPU, NPU, connectivity, and multimedia technologies integrated into a power-efficient platform.
This is an extension of MediaTek’s existing computing business rather than a replacement for it. The company already has its Kompanio family for Chromebooks, including the premium Kompanio Ultra 910. Dimensity CX is being positioned around a newer class of AI-first personal computers, while Kompanio continues to serve Chromebook platforms.
Why MediaTek Is Moving Dimensity Into Personal Computing
The motivation for MediaTek is becoming more linked to the move to AI-driven PCs, where the company would like to see more local computing that doesn’t rely on cloud computing and that may limit the amount of user data sent off to the cloud.
This is also very much aligned with Google’s new Googlebook offering. Google says Googlebook represents a new category of laptops that are based on Android and ChromeOS but with Gemini Intelligence. Google says it is working with Acer, ASUS, Dell, HP, and Lenovo on the first generation of Googlebooks. The first five Googlebooks use Intel or Qualcomm chips; MediaTek is a partner for an upcoming device rather than part of that initial five-device lineup.
8-Core CPU and 11-Core GPU Explained
The C10 Max features an octa-core CPU consisting of a single Cortex-X925 core running up to 3.73GHz clock speed, three Cortex-X4 cores, and four Cortex-A720 cores. It features a total of 12MB of L3 cache and 10MB of system-level cache. MediaTek calls the C10 Max an “All Big Core” design because its eight CPU cores come from the higher-performance Cortex-X and Cortex-A families rather than using a separate efficiency-core cluster.
While this architecture is designed to provide strong performance across demanding workloads, independent benchmarks will be needed to determine how it performs in real-world PCs.
For graphics processing, the C10 Max features an 11-core Arm Immortalis-G925 GPU, alongside LPDDR5X memory running at up to 9600Mbps and UFS 4.0 storage.
55 TOPS NPU Brings On-Device AI to Googlebooks
The C10 Max integrates MediaTek’s NPU 890, rated for up to 55 TOPS of dense AI performance. It supports generative and agentic AI workloads and data formats including INT8, INT16, FP16, and BF16.
The important part is not simply the TOPS number.
MediaTek says the NPU is designed to run AI agents locally, including multimodal workloads, real-time agent workflows, transcription, and summarization. Local processing can reduce cloud round trips and can offer privacy advantages because workloads can remain on the device.
A 55 TOPS figure alone, however, does not establish that the C10 Max will outperform every competing AI PC processor.
3nm Design Targets Thin and Fanless Laptops
The C10 Max is built on TSMC’s advanced 3nm process, with MediaTek positioning the platform for thinner, lighter, and fanless devices. MediaTek also estimates all-day battery life based on Google’s Power Load Test using a 60Wh battery, although actual battery life can vary significantly depending on settings, usage, and other factors. Googlebooks, meanwhile, are designed to meet Google’s platform requirements of more than 45 TOPS of AI performance and at least 14 hours of battery life.
These are Googlebook platform requirements, while MediaTek’s 55 TOPS and battery figures are specific to the C10 Max and its platform claims.
That distinction matters: the 3nm process and efficiency-focused architecture may help manufacturers build lower-power systems, but it does not guarantee a particular battery runtime or mean every C10 Max laptop will be fanless.
Display, Camera and Connectivity Support
The processor supports an internal display of up to 4K at 60Hz and up to two external 4K displays through DisplayPort/MST. It also supports 4K60 video decode and encode, depending on the codec and bit depth. The cameras feature the Imagiq 1090 ISP by MediaTek and can have up to a 32MP main camera with electronic image stabilization and HDR video and auto-zoom.
Connectivity includes Wi-Fi 7 and dual-engine Bluetooth 6.0, giving the platform support for modern wireless peripherals, networking and conferencing.
Dimensity CX C10 Max vs MediaTek’s Existing Computing Chips
The C10 Max represents a shift in MediaTek’s computing strategy. Kompanio remains the company’s established Chromebook platform family, while Dimensity CX introduces a new premium computing brand and flagship-oriented architecture aimed specifically at the new AI-first Googlebook segment.
Independent analysis from Jon Peddie Research has noted that the C10 Max shares substantial architectural similarities with the existing Kompanio Ultra 910, while emphasizing that the more important change is MediaTek’s new premium compute branding and strategy. The C10 Max also builds on technologies MediaTek has developed across mobile and computing, including Arm CPU designs, Immortalis graphics, dedicated NPUs, Imagiq imaging and integrated wireless connectivity.
When Will Dimensity CX C10 Max Devices Launch?
MediaTek says the C10 Max will power an upcoming premium, ultra-portable Googlebook. MediaTek has confirmed to 9to5Google that the C10 Max will appear in an upcoming Lenovo Googlebook. This is not the initial Lenovo Googlebook 15, which uses an Intel processor; the MediaTek-powered Lenovo model is an upcoming device. Google has now opened pre-orders for its first five Googlebook devices from Acer, ASUS, Dell, HP and Lenovo, with retail availability beginning October 4 in the U.S.
Those first five devices use Intel or Qualcomm chips, while the C10 Max-powered Lenovo Googlebook is a separate upcoming model. No confirmed model name, price, or release date has been announced for the C10 Max-powered Lenovo device yet.
It thus seems that the more important part about the C10 Max processor is that MediaTek is introducing its new Dimensity CX premium computing branding into personal computing, with the C10 Max combining a 3nm design, 55 TOPS NPU, CPU and GPU capabilities, and an upcoming Lenovo Googlebook device. This does not mean MediaTek is already broadly established in laptops; the C10 Max’s commercial device remains an upcoming Lenovo Googlebook.
