MediaTek Kompanio 520 vs 528: Which CPU Is Faster?

Which chip is faster

The short answer is that the MediaTek Kompanio 528 is faster than the 520. MediaTek positions the 528 as the higher-tier chip, and it typically offers more processing power for compute-heavy workloads. That means Chromebooks with the 528 will handle demanding tasks like Android gaming, Linux development, and heavy multitasking more smoothly than those with the 520. For a roundup of the best MediaTek Chromebooks, you will see both chips represented.

The 520 is not a slow processor by any means. It is designed for everyday Chromebook use, such as browsing, streaming, and working in Google Docs. But if you need extra performance for simultaneous apps or productivity tools, the 528 is the better pick.

• Faster app launches and smoother multitasking on the 528
• Better support for Android and Linux applications on the 528
• The 520 is efficient for basic tasks and still receives full ChromeOS support

What are the Kompanio 520 and 528

Both the Kompanio 520 and 528 are ARM-based processors made by MediaTek for Chromebooks. They are part of the same family and share a similar architecture, but they are aimed at different price and performance points. The 528 is the upgraded version, so it has a more powerful CPU configuration that results in faster processing. If you are new to Chromebook processors, take a look at our explainer on Chromebook processors.

Because they are ARM chips, they are designed to be power-efficient, which helps Chromebooks run longer on a single charge. This is why most entry-level to mid-range Chromebooks use these processors. Both chips are commonly found in machines from Acer, ASUS, HP, Lenovo, and other major manufacturers.

How the performance differs

The Kompanio 528 outperforms the 520 in every demanding scenario. It has more processing cores and higher clock speeds, which directly translate to faster execution of instructions. For example, when you open a large spreadsheet, switch between many tabs, or run an Android app like a video editor, the 528 will respond faster.

That said, ChromeOS is a lightweight operating system. Even the 520 can deliver a pleasant experience for the vast majority of tasks. If you stick to web browsing, email, and video playback, you likely will not notice a difference. The gap becomes noticeable only when you push the chip with heavy multitasking or resource-intensive applications.

If you plan to use Linux on your Chromebook for programming or other development work, the 528 is strongly recommended. The Linux environment on ChromeOS is built into the system, but it requires enough CPU and memory to run smoothly. With the 528, compilation times are shorter and apps feel more responsive.

Chromebook Plus and what it means for these chips

Google's Chromebook Plus tier sets a baseline for hardware specifications. According to Google, Chromebook Plus devices come with at least 8GB of RAM and 128GB of storage. This requirement does not mention a specific processor, but it strongly suggests that a faster chip like the Kompanio 528 is paired with these configurations. Browse our list of Chromebook Plus laptops to see what is available.

If you are looking at a Chromebook with the Kompanio 520, it is unlikely to be a Chromebook Plus model, because the 520 is usually paired with lower RAM and storage. On the other hand, the 528 is often found in Chromebook Plus devices, which also bring extra features like better cameras and Gemini AI integration.

For buyers, this means the 528 not only gives you more processing power but also opens the door to the Chromebook Plus ecosystem, which includes additional AI-powered tools and software benefits.

Which processor should you pick

Your choice between the Kompanio 520 and 528 should be based on how you use your Chromebook. If you primarily browse the web, check email, and watch videos, the 520 is more than enough. It keeps the device affordable and efficient, and it still gets the same ChromeOS updates as the 528.

If you are a student who runs multiple apps at once, or you plan to use Android apps and Linux tools, the 528 is worth the upgrade. The extra performance will help you avoid slowdowns and make your workflow feel snappier.

For business users handling spreadsheets, video calls, and cloud apps, the 528 is the safer choice. It ensures that your Chromebook stays responsive even when you have many workspace tabs open or you are using video conferencing software alongside other tools.

Longevity and update support

Both the Kompanio 520 and 528 are used in modern Chromebooks that are eligible for Google's 10-year update policy. According to Google's Auto Update policy, ChromeOS devices receive automatic updates for 10 years from the platform release date. This means you can expect both chips to keep your Chromebook secure and feature-rich for a long time.

There is no difference in update support between the two processors. Whether you pick the 520 or the 528, you will get the same ChromeOS updates, including security patches and new features, for the full support window.

If long-term reliability is your priority, either chip will serve you well. The 528 just gives you more performance headroom, which may make the device feel less dated over time.

Other specs to consider alongside the CPU

While the processor is an important factor, it is not the only spec that determines a Chromebook's performance. RAM and storage play equally significant roles. A Chromebook with the Kompanio 528 but only 4GB of RAM will feel sluggish, while a 520 with 8GB of RAM can handle more tasks smoothly. For a deeper dive, see our guide to RAM on Chromebooks.

That is why you should look at the whole package. Aim for at least 8GB of RAM and 128GB of storage, especially if you want to use Android apps or Linux. Storage also matters for offline use and for storing files locally. Check out the best Chromebooks with 8GB RAM for models that balance specs well.

If you are deciding between a cheaper 520 model with 8GB of RAM and a pricier 528 model with 4GB of RAM, the 520 is the better choice. For most people, RAM has a bigger impact on daily performance than the processor.
