A MediaTek Kompanio processor is a system-on-chip (SoC) designed for Chromebook platforms. It combines computing components such as CPU cores, graphics and video processing on one chip; depending on the model, it can also include AI processing. Kompanio chips are built into complete Chromebooks, not ordinarily sold as consumer upgrade parts.
What does the Kompanio name cover?
MediaTek groups its Kompanio range into three Chromebook tiers: premium, mainstream and entry. Those are the manufacturer’s positioning labels, not an independent ranking of the finished laptops. The computer’s memory, storage, screen, cooling and software configuration also shape its performance and capabilities. MediaTek’s portfolio lists the Ultra 910 as premium; the 838, 828 and 820 as mainstream; and the 540, 528, 520 and 500 as entry.
The portfolio also names example Chromebook models, including Lenovo Chromebook Plus (14-inch, 10) with Kompanio Ultra; Lenovo Slim 3, ASUS CM30, HP Fortis and Lenovo 300e with Kompanio 520; Acer Chromebook R724T with Kompanio 528; and Lenovo Duet with Kompanio 500. These are examples from MediaTek, not a guarantee that every regional or retail configuration sharing a product name has the same processor. Check the exact configuration in the product listing.
How do representative Kompanio chips differ?
The specifications below are chip-level capabilities published by MediaTek. A Chromebook maker determines which supported memory, storage, display, ports and wireless features actually appear in a finished device.

MediaTek notes that 4K60 display is not supported in Kompanio 540 Chromebooks, despite listing an external 4K60 capability at chip level. |
Kompanio Ultra 910
MediaTek positions the Ultra 910 for premium Chromebooks. Its listed CPU combines one high-performance Cortex-X925 core with three Cortex-X4 and four Cortex-A720 cores. Its support for LPDDR5X, UFS 4.0 and an 11-core GPU describes what the chip can support; it does not establish the RAM, storage, ports or display arrangement of every Ultra-powered laptop. MediaTek’s Ultra 910 page calls out up to 50 TOPS of AI performance. That is a manufacturer specification, not an independent measurement.
Kompanio 838
The 838 uses two Cortex-A78 cores and six Cortex-A55 cores with a Mali-G57 MC3 GPU. MediaTek lists eMMC 5.1 storage, LPDDR4X or DDR4 memory, AV1 hardware decoding, dual-display support and an AI accelerator rated up to 4 TOPS. The company’s 838 page claims up to 76% faster graphics performance, up to 66% greater CPU-based benchmark performance and up to 60% greater web-based benchmark performance versus the Kompanio 500 series. These are vendor comparisons with that stated baseline, not independent benchmarks of retail Chromebooks.

Kompanio 540
The entry-tier 540 has the same stated CPU core arrangement and maximum CPU frequencies as the 838, but a Mali-G57 MC2 GPU. It supports either LPDDR5 or LPDDR4X memory and UFS 3.1 or eMMC 5.1 storage. Its video decoding support does not mean a Chromebook can output video to an external 4K60 display: MediaTek explicitly says that 4K60 display is not supported in Kompanio 540 Chromebooks. This is a practical example of why a chip specification should not be treated as a laptop specification.
MediaTek’s 540 page claims 50% higher CPU single-core performance and 30% higher CPU multi-core performance than the Kompanio 520 using Geekbench 6, and 75% higher graphics performance using GFXBench Manhattan 3.0. It also claims up to 35% longer battery life versus direct alternative processors. These are manufacturer-stated comparisons; the battery figure is not a promise of a particular Chromebook’s runtime.

What should you check when buying a Kompanio Chromebook?
Compare complete computers, not just the Kompanio family name. Two Chromebooks with chips from the same tier can differ in useful ways, and a chip’s supported features may not be implemented in a particular model.
- Exact processor: Confirm the specific Kompanio model in the listing or maker’s specification sheet. A family or product name alone may cover different configurations.
- Memory and storage: Check RAM capacity and type, plus storage type and capacity. Chip-level support for a faster memory or storage standard does not prove that the laptop includes it.
- Screen and external displays: Check the built-in display resolution and the manufacturer’s stated external-display support. Do not infer monitor support solely from a chip page.
- Ports and wireless: Verify the ports and Wi-Fi and Bluetooth versions for the exact computer. Chip support for a standard does not guarantee that the device exposes it.
- Your workload: Consider what you actually do—such as browsing, video playback, schoolwork or multitasking—and compare the full configurations rather than relying on tier labels or vendor benchmark percentages.
- Battery claims: Look for a runtime claim tied to the specific Chromebook and its test conditions. A processor-level comparison is not a direct prediction of your battery life.
MediaTek’s portfolio is useful for identifying its intended tiers and example devices, but the Chromebook manufacturer’s model-specific specifications are the better place to confirm what a computer actually includes. MediaTek’s product pages describe its own chips and claims; they do not independently establish real-world speed, battery life or comparative quality.
