  • Key Specs
    • Processor Model: AMD Ryzen 5 7000 Series (Your computer's processor is like its brain. Working in combination with system memory, the power of the processor determines the complexity of software you can run, how many programs you can have open at the same time, and how fast those programs will run. Most computers feature an AMD, Intel or Snapdragon processor.)

    • Total Storage Capacity: 512 gigabytes
    • System Memory (RAM): 16 gigabytes (Random-access memory (RAM) is a computing device's short-term data storage, which allows active information to be accessed quickly. The size and type of RAM determines how efficiently the device can handle large amounts of information at one time. For example, gaming or video editing requires more RAM for optimal performance.)
    • Graphics Type: Integrated (Dedicated graphics uses a separate graphics card for processing video images. Because it does not use memory from the system's RAM, there is no extra burden on the CPU and graphics are processed more efficiently. Integrated graphics shares system RAM to process video images.)

    Great Box

    I recently purchased the Kamrui E3B 4K Mini PC and I’m extremely impressed with the performance for the price. It runs on an AMD Ryzen V2748 processor (up to 4.3 GHz) with 16GB of DDR4 RAM and a 512GB SSD, and it feels very fast and responsive for everyday use. Setup with Windows 11 Pro was quick and easy, and the system boots up in seconds thanks to the SSD. I’ve been using it for web browsing, office work, media streaming, and light multitasking, and it handles everything smoothly without slowdowns. The 4K display support is great for watching high-resolution content, and the WiFi 6 connectivity provides fast and stable internet speeds. Another thing I really like is how compact and quiet the unit is. It takes up almost no space on the desk but still delivers solid desktop-level performance. I was lucky to buy it on sale, which made the value even better. At the discounted price, it’s honestly a fantastic deal for the specs and performance you get. If you’re looking for a small, capable PC for home or office use, this is definitely a great option.

    Does what it needs to do

    It’s a nice mini PC that it can run a lot of programs with ease. Don’t expect anything groundbreaking but it will play 360/PS3 era games and even PS4 era games very well which is exactly what I was looking for in the world of consoles lacking backwards compatibility with older titles. It looks and feels very nice and is responsive.

    Exceeds expectations

    Windows 11 preinstalled, more than enough specs for me to stream on Twitch, and portable!
