Intel Celeron N4020 Review: A Budget-Friendly but Limited Processor

The Intel Celeron N4020 is a low-end dual-core processor based on the Gemini Lake architecture. It was released in late 2019, targeting the budget laptop market. The N4020 is part of Intel’s Celeron line of CPUs, which are designed to provide basic performance for affordable devices. Key features of the N4020 include:

  • Dual-core design with two CPU cores
  • Base clock speed of 1.1 GHz, up to 2.8 GHz with Turbo Boost
  • 6W TDP for power efficiency
  • Support for DDR4-2400 and LPDDR4-2400 RAM
  • Integrated Intel UHD Graphics 600
  • 14 nm manufacturing process

The N4020 is aimed at very budget-friendly laptops and ultraportables where strong CPU performance is not critical. Its main appeal is power efficiency for basic productivity and web browsing. The target market is undemanding users who need a portable machine for web browsing, office tasks, streaming media, and video calls. It competes against other low-power chips like the AMD A9-9420e. Compared to Intel’s faster Core i3 and Core i5 U-series processors, the Celeron N4020 sacrifices performance in exchange for a lower cost. This makes it popular among manufacturers of affordable, entry-level laptops.

Technical Specifications of Intel Celeron n4020

The Intel Celeron N4020 is built on a 14 nm process node and features the following technical specifications:

  • Core and thread count: 2 cores and 2 threads
  • Base clock: 1.1 GHz
  • Boost clock: 2.8 GHz
  • Power rating and TDP: 6W TDP for power efficiency
  • Manufacturing process and architecture: 14 nm Gemini Lake architecture
  • Integrated graphicsIntel UHD Graphics 600 with a base frequency of 200 MHz and a boost frequency of 650 MHz
  • Memory support: DDR4-2400 and LPDDR4-2400 RAM

The Celeron N4020 is designed for low-end laptops and ultraportables, providing basic performance for tasks such as web browsing, office productivity, and media playback. It competes with other low-power processors like the AMD A9-9420e and is not suitable for demanding workloads like video editing or gaming.


The Intel Celeron N4020 offers basic CPU performance suitable for light workloads. Here is how it compares to some other low-end processors:

  • The N4020 has similar base clocks but higher boost potential versus the N4000. The quad-core N4120 offers better multi-threaded performance.
  • Suitability for daily tasks:

The N4020 is suitable for basic productivity and entertainment:

  • Web browsing
  • Office documents
  • Media playback
  • Video conferencing

It can handle these tasks well but struggles with more demanding workloads like heavy multitasking, high-resolution video editing, 3D modeling, etc.


The main limitations stem from the low base clock, dual-core design, and basic integrated graphics:

  • Slow performance in CPU-intensive applications
  • Limited multitasking ability
  • Unable to run modern 3D games smoothly

For demanding users, the N4020’s performance is quite limited compared to mid-range and high-end processors. But it provides adequate speed for light everyday workloads on a tight budget.

Real-World Usage

Since its launch in late 2019, the Intel Celeron N4020 processor has been adopted by several laptop manufacturers in affordable entry-level models. Here are some examples of laptops featuring the Celeron N4020:

  • HP Stream 11 – 11.6″ budget ultraportable with 4GB RAM and 64GB eMMC storage
  • Asus Laptop L210 – 11.6″ lightweight laptop with 4GB RAM and 128GB SSD
  • Lenovo IdeaPad 1 14 – 14″ laptop with 4GB RAM and 128GB SSD
  • Acer Aspire 1 – 14″ budget laptop with 4GB or 8GB RAM options

These are all basic laptops focused on portability and value, with the N4020 providing just enough performance for web browsing and office work. User reviews of N4020-powered laptops highlight the pros and cons:


  • Low cost
  • Lightweight and portable
  • Long battery life
  • Handles basic tasks well


  • Limited performance for demanding apps
  • Low amount of RAM on some models
  • No touchscreen on most models

Overall, the Celeron N4020 hits a sweet spot between price and functionality for casual users looking for an affordable machine for web, media, and document-based tasks. It may disappoint power users wanting to multitask extensively or run heavy applications.


The Intel Celeron N4020 offers basic dual-core performance that is just enough for light daily workloads like web browsing, office productivity, and media playback. Its strengths are power efficiency, affordability, and portability. In summary, the Celeron N4020 provides:

  • Adequate performance for light multitasking
  • Ability to handle common tasks like web browsingOffice documents, and video streaming
  • Very budget-friendly pricing
  • Low power draw enabling long battery life
  • Compact footprint well-suited for small laptops

However, its limited processing power means the N4020 struggles with intensive workloads like heavy multitasking, high-res video editing, 3D modeling, etc. It also has basic integrated graphics unable to handle modern 3D gamingFor potential buyers, the Celeron N4020 is a reasonable option for an affordable secondary or travel laptop focused on portability and battery life.

It can capably handle everyday web browsing, documents, emails, and media usage. Just don’t expect high speeds for demanding creative work or gaming. Those looking for stronger performance should consider mid-range processors like the Intel Core i3 or AMD Ryzen 3 instead.
