MediaTek Kompanio 520 vs 828: Which Processor Is Better?

Processor basics: what the Kompanio 520 and 828 are

MediaTek's Kompanio series targets Chromebooks and other ChromeOS devices. The 520 and 828 are two Arm-based processors designed for different performance levels. The 828 sits above the 520 in MediaTek's lineup, meaning it aims at faster, more capable machines. Both support ChromeOS features like Android app compatibility and Linux, but the 828 is built for heavier workloads. If you're comparing MediaTek Chromebooks, you'll see these chips often in budget and mid-range models.

When you compare processors, core count and clock speed matter most for everyday responsiveness. The Kompanio 828 has eight cores, while the 520 also has eight cores, but the 828 runs at higher clock speeds. More cores help with multitasking, and higher speeds make individual tasks feel snappier. The 828 also includes a more powerful GPU for graphics-heavy work.

Neither processor is new in 2026, but both remain common in budget and mid-range Chromebooks. The 520 is often found in entry-level models, while the 828 appears in machines that advertise faster performance. If you see a Chromebook with the 828, you can expect it to handle more than basic web browsing.

Core counts and clock speeds compared

The Kompanio 520 has a 2.0 GHz octa-core CPU, and the 828 has a 2.2 GHz octa-core CPU. Both have eight cores, so the difference comes down to speed. The 828's higher clock speed means it can finish tasks faster, such as loading complex web pages or switching between apps.

In practice, the 828 handles heavy multitasking better. If you keep many browser tabs open or run Android apps side by side, the extra clock speed helps. The 520 is fine for lighter use, but it can slow down when you push it with many apps at once.

For most students and office workers, the 520 is enough for writing documents, checking email, and streaming video. The 828 is the smarter choice if you plan to do video editing, run Linux tools, or play Android games. These tasks benefit from the faster cores.

Remember, clock speed is not the only factor. The 828 also has a more efficient design, which helps it keep performance high without draining the battery quickly. Chromebooks with the 828 often last through a full school or workday.

Graphics and display support

The GPU inside the Kompanio 828 is stronger than the one in the 520. This affects how well your Chromebook handles visual tasks like playing videos, using Google Earth, or running Android games. The 828 can push more pixels, so it works well with higher-resolution displays, including Full HD and some 2K panels.

The 520's GPU is enough for standard 1080p video streaming and casual games, but it may struggle with graphically intense Android apps. If you want a Chromebook for cloud gaming or video editing, the 828 is the better option. Its GPU helps render frames faster and reduces lag.

Display quality also depends on the panel. A Chromebook with the 828 and a 1080p screen will look sharper than one with the 520 and the same resolution, because the GPU can handle the extra pixels more smoothly. For 4K external monitors, the 828 is the safer pick, though you'll want to check the specific port capabilities. Learn more about display resolution and how it pairs with your processor.

If you connect to an external monitor, the 828 supports higher refresh rates, which makes scrolling and video feel fluid. The 520 works with standard monitors but lacks the bandwidth for very high refresh rates.

Memory and storage considerations

The processor you choose often pairs with specific memory and storage configurations. Chromebooks with the Kompanio 828 typically come with 8GB of RAM or more, while those with the 520 often have 4GB or 8GB. For ChromeOS, 8GB is the sweet spot for smooth multitasking, as Google notes on its Chromebook Plus page. If you're considering a model with 8GB, browse our 8GB RAM Chromebooks list.

The 828 supports faster LPDDR4X memory, which helps data move quickly between the CPU and RAM. This makes app loading snappier and handles large files better. The 520 also supports LPDDR4X, but the 828's memory controller is tuned for better throughput.

Storage options vary more by model than by processor. Both chips work with eMMC and NVMe SSDs. If you want a Chromebook for Linux development or many offline files, look for a model with an SSD and at least 64GB of storage, regardless of the processor.

For cloud-based work, where most files live in Google Drive, the 520 with 8GB of RAM and 64GB of storage is a solid setup. If you plan to install Android apps or Linux packages, spring for the 828 with more RAM and storage.

Connectivity and extra features

The Kompanio 828 includes support for Wi-Fi 6 and Bluetooth 5.2, while the 520 only has Wi-Fi 5 and Bluetooth 5.0. Wi-Fi 6 is faster and more stable in crowded networks, like at school or in a coffee shop. If you rely on a strong internet connection, the 828's newer wireless standard is a real benefit. See our Wi-Fi standards guide for more details.

Both processors support USB-C, which lets you charge and connect peripherals. The 828 also handles multiple external displays, while the 520 supports just one. If you like working with a second monitor, the 828 is the better choice.

MediaTek's 828 also includes a newer image signal processor for better webcam quality. Video calls look sharper, with improved low-light performance. The 520's ISP is simpler, so built-in webcams tend to be less detailed.

For Chromebook Plus models, Google requires at least 8GB of RAM and 128GB of storage, and the 828 meets those specs. The 520 often appears in standard Chromebooks without the Plus badge. If you want AI features like Gemini integration, a Chromebook Plus with the 828 is a future-proof pick.

Battery life and efficiency

Arm processors are known for energy efficiency, and both the 520 and 828 deliver all-day battery life. The 520 uses a smaller 8nm process, while the 828 uses a more advanced 6nm process. The 6nm chip wastes less power, so the 828 actually improves efficiency despite its higher clock speeds.

In practice, a Chromebook with the 828 can last just as long as one with the 520, sometimes longer, especially under light use. Chromebooks with these chips typically get 10 to 12 hours of battery life, depending on the screen and your workload. Google's update policy notes that devices receive 10 years of updates, so you won't need to upgrade often.

Efficiency also means less heat. The 828 runs cooler than the 520 under stress, so fanless designs are more common with the 828. If you prefer a silent Chromebook, the 828 is the better match. The 520 may require a fan in some models to keep temperatures in check. Check our fanless design article if this matters to you.

For students who carry their Chromebook all day without a charger, the 828 is a safe bet. It balances performance with power draw, giving you speed when you need it and battery life when you're just browsing. Explore best student Chromebooks to see which models pack these processors.

Which processor should you choose?

Your choice between the Kompanio 520 and 828 depends on how you use your Chromebook. If you mostly browse the web, watch YouTube, and write in Google Docs, the 520 is perfectly adequate. It handles everyday tasks with ease and keeps costs down. You can find options in our best MediaTek Chromebooks roundup.

Choose the 828 if you multitask heavily, play Android games, or run Linux applications. The higher clock speed and better GPU make a visible difference in these scenarios. It also future-proofs your purchase if you plan to keep the Chromebook for several years.

Consider the screen: If you want a Full HD or higher-resolution display, the 828 pairs better. It pushes pixels more smoothly, especially when scrolling or watching video. The 520 works with 1080p, but it may feel less fluid. Read our screen size guide to pick the right display along with the processor.

For students in elementary or middle school, the 520 is often enough for classroom tools and video calls. High school and college students who need to run more demanding software should invest in the 828. The extra performance justifies the price difference for those users.
