The MediaTek Kompanio Ultra 910 is a premium ARM-based system-on-chip built for high-end Chromebook Plus laptops. It combines an eight-core Armv9.2 CPU, an 11-core Immortalis-G925 GPU, a dedicated NPU for on-device AI workloads, fast LPDDR5X memory support, modern video engines, and connectivity features such as Wi-Fi 7.
Its published performance is impressive for ChromeOS, especially in browser-heavy productivity and multitasking. However, MediaTek’s headline benchmark figures come from a development board rather than a broad set of retail laptops. Independent testing of the Lenovo Chromebook Plus 14 provides a more realistic picture, but those results describe the complete laptop—not just the processor.
Quick verdict
- Performance: Excellent for ChromeOS browsing, productivity, multitasking, and supported Android applications.
- Gaming: Capable for supported mobile and ChromeOS games, but not a replacement for a Windows gaming laptop.
- Battery life: Potentially excellent, although results depend on the laptop’s battery, display, firmware, and power settings.
- AI: The NPU is rated for up to 50 TOPS, but real-world AI features depend on ChromeOS and application support.
- Compatibility: Check ARM support, Linux requirements, peripherals, and ChromeOS limitations before buying.
- Value: Strong for a premium Chromebook buyer, but a similarly priced Windows laptop may be more versatile.
Bottom line: The Kompanio Ultra 910 is one of MediaTek’s most ambitious Chromebook platforms and appears to be among the fastest ARM options for ChromeOS. Buy it when you specifically want a quiet, efficient, premium Chromebook. Do not buy it solely because of its TOPS or vendor benchmark claims.
What is the MediaTek Kompanio Ultra 910?
The Kompanio Ultra 910 is an ARM-based Chromebook SoC, not a conventional desktop processor sold as a standalone upgrade. MediaTek designed it primarily for premium Chromebook Plus systems, where the processor, graphics, memory controller, media engines, connectivity, and AI accelerator are integrated into one platform.

“MediaTek” is the brand, “Kompanio Ultra” identifies the Chromebook platform family, and “910” is the specific processor designation. It should not be confused with the older Kompanio 838, Kompanio 1200, Kompanio 1380, or MediaTek’s smartphone chip families. MediaTek’s official specifications are available on its Kompanio Ultra product page.

CPU architecture explained
The Kompanio Ultra 910 uses eight relatively large Arm CPU cores:
- 1× Cortex-X925: the high-performance prime core, advertised at up to 3.62GHz.
- 3× Cortex-X4: additional high-performance cores for demanding workloads.
- 4× Cortex-A720: performance-oriented cores intended to handle sustained and background work more efficiently than the prime core.
This is an all-big-core design by Chromebook standards. It does not rely on the traditional arrangement of a few large performance cores alongside very small efficiency cores. That design can benefit bursty, interactive tasks such as opening tabs, switching between web applications, editing documents, and responding to browser scripts.
It does not guarantee a particular benchmark score or battery result. ChromeOS scheduling, cooling, firmware, memory capacity, storage speed, display resolution, and the laptop chassis all affect performance. A thin fanless Chromebook and a better-cooled model can therefore behave differently even with the same Kompanio Ultra 910.
GPU and gaming performance
Graphics are handled by the integrated Arm Immortalis-G925 MC11, with 11 graphics cores and silicon-level hardware ray-tracing capability. The GPU uses shared system memory rather than dedicated laptop graphics memory.
MediaTek reports a GFXBench Manhattan score of 18,124 in its own testing. That is a vendor-published result and should not be treated as a universal score for every retail Chromebook.
Recommended Free Tools
There is also an important limitation: although the GPU supports ray tracing at the hardware level, MediaTek states that ray tracing is not supported on ChromeOS. Buyers should not interpret “Immortalis” or “ray-tracing-capable” as a promise of desktop-style ray-traced gaming on a normal Kompanio Ultra Chromebook.
In TechRadar’s testing of the Lenovo Chromebook Plus 14, Asphalt Legends ran smoothly at high settings and Call of Duty: Mobile was playable at maximum settings. Alien: Isolation was less impressive but remained playable. These are useful indications of the tested laptop’s gaming behavior, not universal frame-rate guarantees for every Kompanio Ultra 910 system. Android game compatibility, ChromeOS support, thermal limits, and game optimization still matter.

AI performance: what 50 TOPS really means
The Kompanio Ultra 910 includes MediaTek’s NPU 890, rated for up to 50 TOPS of AI performance. Lenovo lists an overall platform figure of up to 67 TOPS when other compute resources are included.
TOPS means trillions of operations per second under a specified workload. It is a theoretical throughput measurement, not a direct prediction of how quickly every AI application will run. Actual performance depends on:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- whether an application can use the NPU;
- the model’s precision and architecture;
- ChromeOS and Google service integration;
- available memory and storage;
- whether the workload runs locally or in the cloud; and
- software optimization for this specific accelerator.
Therefore, 50 TOPS does not mean that every generative-AI tool will run locally, quickly, or offline. MediaTek’s qualification material also says that agentic AI is not supported on ChromeOS, despite positioning the platform as ready for that class of workload. Treat the NPU figure as evidence of hardware capability rather than a guarantee of current Chromebook features.
Memory and storage options
The platform supports LPDDR5X memory at up to 8533Mbps and UFS 4.0 storage. The Lenovo Chromebook Plus 14 is documented with 12GB or 16GB of soldered LPDDR5X-8533 memory, alongside either 128GB UFS 3.1 or 256GB UFS 4.0 storage.
Those configurations are not interchangeable in practice. The 16GB model is the safer choice for many browser tabs, large web applications, Android apps, and Linux containers. The 256GB UFS 4.0 model also offers more space and a newer storage interface than the 128GB UFS 3.1 version.
Lenovo’s representative Chrome 14M9610 design has no user-upgradable RAM or storage. Choose the capacity you need when purchasing rather than assuming it can be expanded later. See the detailed Lenovo PSREF specification sheet.

Video, displays, and connectivity
The media engine supports 4K60 10-bit decoding for HEVC, AVC, VP9, and AV1. It supports 4K60 10-bit HEVC and AVC encoding, plus 4K60 8-bit HEVC encoding. This makes the platform well suited to high-resolution streaming and video playback without requiring the CPU to perform all the work.
At the platform level, MediaTek lists an internal display up to 4K60 and support for up to two external 4K displays. Wi-Fi 7 support is specified at up to 7.3Gbps, while Bluetooth 6.0 is also listed.
These are maximum capabilities, not promises about every laptop. Lenovo’s Chrome 14M9610 documentation specifies up to three independent displays in total, but its two USB-C ports do not have identical limits: one supports up to 4K at 30Hz and the other up to 4K at 60Hz. The ports use DisplayPort 1.4 and USB 5Gbps connectivity. Dock users should check the exact port assignment before buying.

MediaTek says the testing used a Google-MediaTek development board running ChromeOS 133, with Geekbench 6.2 specified for the CPU comparison. Competitor figures in the same promotional material came from different laptops and operating-system configurations. The results are consequently useful as an indication of the platform’s potential, but they are not a controlled, independent, chip-to-chip laboratory comparison.
Claims such as being faster than competing Chromebook processors or using less power should also be read as vendor claims tied to MediaTek’s stated hardware and methodology. They do not establish a universal ranking across all production laptops.
Independent Chromebook benchmarks
The most useful independent evidence currently comes from testing a complete laptop: the 16GB/256GB Lenovo Chromebook Plus 14. TechRadar recorded:
| Test | Result |
|---|---|
| JetStream 2 | 288.364 |
| Kraken | 398.8ms |
| Speedometer 3.1 | 26.6 ±0.45 |
| Battery test | 14 hours 4 minutes |
The browser scores indicate strong ChromeOS responsiveness, while the battery result is a useful real-world reference for that particular configuration. It should not be presented as a processor-only battery figure.

Browser and productivity work
This is the processor’s clearest use case. A fast prime core, three additional Cortex-X4 cores, and four Cortex-A720 cores give premium Chromebook systems plenty of headroom for Google Workspace, web-based office suites, research tabs, video calls, cloud dashboards, and simultaneous browser applications.
Memory capacity remains important. A 16GB model is better suited to sustained multitasking than an 8GB configuration, while 12GB can be a sensible middle ground for ordinary productivity.
Streaming and video calls
Hardware decoding for AV1, VP9, HEVC, and AVC supports 4K streaming efficiently. The actual viewing experience still depends on the display, network, streaming service, browser, and the laptop’s thermal design.

Android and Linux applications
ChromeOS generally supports Android applications and Linux containers, but ARM compatibility is not identical to x86 compatibility. Many common applications work well, while specialized tools, native extensions, development packages, or peripherals may require an ARM build or compatibility layer. Check the exact application requirements before purchasing if Linux or Android software is central to your workflow.
Thermals and noise
The efficient ARM platform is well suited to thin and quiet Chromebook designs, including fanless systems. That does not mean every Kompanio Ultra 910 laptop will have identical thermals. Sustained workloads depend on chassis design, cooling, power limits, and firmware.
Kompanio Ultra 910 versus alternatives
There is no single winner without matched testing and a clear operating-system requirement. Compare platforms by use case:
- Lower-cost Chromebook processors: cheaper systems can handle basic browsing and documents, but the Ultra 910 is aimed at heavier multitasking, premium displays, faster storage, and longer-term performance headroom.
- Intel Core i3 or N-series Chromebooks: Intel systems may offer familiar x86 compatibility and attractive prices. The Ultra 910 may be preferable for quiet operation, integrated AI hardware, and ARM efficiency, but MediaTek’s development-board results are not a fair universal head-to-head.
- Intel Core Ultra Chromebooks: Intel may be the safer choice for specific Linux, x86, or peripheral requirements. The Kompanio platform can be attractive when efficiency, fan noise, and ChromeOS responsiveness matter more.
- Qualcomm Snapdragon Windows laptops: Snapdragon Windows machines provide Windows software and a different ARM ecosystem. They are not directly comparable to a ChromeOS device because application compatibility and operating-system behavior differ.
- Apple silicon MacBooks: Apple silicon remains a separate macOS platform with different software, pricing, and hardware. The Kompanio Ultra 910 is relevant only if ChromeOS is the desired environment.
Do not use the Kompanio Ultra 910’s 8,000 Geekbench multi-core result as a definitive comparison with Core Ultra, Snapdragon X Plus, Ryzen, or Apple M-series processors. The available figures were not produced under equivalent conditions.
