  • Perfect for students and casual users who only need a device for browsing, streaming, and light productivity work.
  • Relies on cloud storage, so there’s less need for large amounts of internal file system storage.
  • Fast startup times and automatic updates for better performance and security.
  • A simple, real time operating system that requires little to no maintenance.

Best for: Students, casual users, and those looking for a budget-friendly, low-maintenance computer.

If you need a system that runs real-time operating systems or process management software that manages computer systems, make sure your OS is compatible before choosing ChromeOS.new c

What To Look For When Buying A New Computer

Processing Power & Performance

The processing power of your computer plays a huge role in how well it performs. The CPU (central processing unit) is the engine of your computer, determining how fast tasks are completed and how well your system handles multiple applications.

Understanding CPU Choices

Intel and AMD operate as the leading CPU manufacturers who provide product lines that match various performance requirements.

Entry-Level (Basic Everyday Tasks)

  • Intel Core i3 / AMD Ryzen 3 – Best for simple tasks like browsing the web, checking emails, watching videos, and using office applications.

Mid-Range (Work, Study & Moderate Use)

  • Intel Core i5 / AMD Ryzen 5 – A great option for students, professionals, and everyday users looking for a fast and reliable computer without overspending.

High-Performance (Gaming, Video Editing & Heavy Multitasking)

  • Intel Core i7 / AMD Ryzen 7 – A powerful option for those who need their computer to handle video editing, gaming, coding, or demanding workloads.

Extreme Performance (For Professionals & Power Users)

  • Intel Core i9 / AMD Ryzen 9 – Built for serious gamers, developers, content creators, and engineers who need top-tier performance. Ideal for handling complex computing tasks, 3D rendering, and ultra-high-resolution video editing without slowdowns.

Laptops vs. Desktops

A desktop computer provides future upgrade flexibility through its replaceable CPU, RAM and storage components which makes it an excellent long-term investment. When selecting a laptop you must choose the correct specifications at purchase because these components cannot be changed after production.

For most users: An Intel Core i5 or AMD Ryzen 5 offers a great balance of performance and price. If you’re dealing with process management software, video editing, or other demanding tasks, go for an i7 or better for a smoother experience.

Memory & Storage

 

RAM (Random Access Memory)

RAM is required by your computer to perform well during multitasking operations. If you don’t have enough, your system can slow down, even with a powerful CPU.

Recommended RAM sizes:

  • 4GB RAM – Basic performance, suitable for light tasks like web browsing and emails.
  • 8GB RAM – Ideal for students and office work, handling common programs like Microsoft Office smoothly.
  • 16GB RAM – Great for gaming, video editing, and multitasking without lag.
  • 32GB+ RAM – Best for professionals working with real-time operating systems, software development, or intensive computing tasks.

Storage

The file system of your computer will dictate how fast your computer will be in processing data. The decision between an SSD and an HDD plays a crucial role in the effectiveness of the device’s performance and functionality.

  • SSD (Solid-State Drive) – Much faster than an HDD, consumes less power, and is perfect for laptops and high-performance computing.
  • HDD (Hard Disk Drive) – Offers larger storage at a lower cost, but is significantly slower.

Suggested storage sizes:

  • 256GB SSD – A good starting point for most users.
  • 512GB SSD – Great for professionals handling large documents, videos, and software.
  • 1TB HDD + SSD combo – Best for those who need both speed and high-capacity storage.

Graphics and Display

For gamers, video editors or those who engage in 3D rendering, the graphics card is a very important component. A good GPU enhances the display quality of your computer, increases the rate at which images are processed, and enhances the performance of your computer.

  • Spill-resistant keyboards are a lifesaver for students and professionals who work on the go.
  • Strong, high-quality hinges prevent the screen from wobbling and wearing out too quickly.

Ports & Connectivity

  • USB-C / Thunderbolt 4 – Speeds up charging and data transfer.
  • HDMI / DisplayPort – Lets you connect an external monitor, TV, or projector.
  • Ethernet Port – Essential for stable, high-speed internet, especially for work or gaming.

Battery Life

When buying a laptop, battery life is something you’ll want to keep in mind.

  • 5–7 hours – Budget laptops that have to be charged quite often.
  • 8–10 hours – This is suitable for students, working people, and anyone who needs a comfortable chair for daily use.
  • 10+ hours – It is suitable for travelers and those who need a device with a powerful battery charge, but there are no outlets nearby.

By focusing on these aspects, you will be able to get a laptop or a desktop that is sturdy, functional and durable.
