Thelio mountains
Thelio Major now available with AMD Ryzen Threadripper 3990X. See what 64 cores can do for you

“With 64 Cores, your desktop has full command over CPU-intensive workloads. But how much of a difference can 64 Cores make?”

Apply a circular motion blur in 44 seconds

Motion blur

Much of the design process is bogged down from waiting for your design program to, as top-notch designers say, “Just finish already!” With 64 Cores, you can stay focused on modifying your image, rather than your schedule. Use the following instructions to replicate this test on your own machine. How does your computer measure up #vs3990X?

Warning: Regular computers and weak-minded robots may be utterly obliterated under pressure from attempting to perform such an intensive task.

  1. Download the image

  2. Install GIMP and the Clocks App

    sudo apt install gimp gnome-clocks
  3. Open the Clocks app to use as a stopwatch

  4. Open the heic1206a.jpg image in GIMP

  5. Click the Convert button when prompted

  6. Click Filters > Blur > Circular Motion Blur

  7. Click Okay

Compile the linux kernel in 24 seconds

Screenshot of Linux kernel compilation

When working within tight deadlines, it’s comforting to know that compiling code on a regular basis won’t cause you major delays. AMD’s Threadripper 3990X accelerates the code-compile-run cycle so you can ensure that your work runs flawlessly upon release. Use the following instructions to replicate this test on your own machine. How does your computer measure up #vs3990X?

  1. Download dependencies

    sudo apt-get install libncurses-dev flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf
  2. Download the kernel source

  3. Untar the archive and change into the kernel directory

    tar xvf linux-5.5.1.tar.xz && cd linux-5.5.1/
  4. Configure

    make defconfig
  5. And compile!

    time make -j $(nproc)

Render a blender scene in 76 Seconds

(It was a coincidence, we swear)

Blender scene rendered

Watching your project render is like watching paint dry, except in this case the paint is also using up much of your computer’s resources. So we tried it on a computer that can take the heat and quickly channel it out the exhaust port. Use the following instructions to replicate this test on your machine at home. How does your computer measure up #vs3990X on Thelio Major?

  1. Download dependencies

    sudo apt install php-cli php-common php-xml php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-readline php7.3-xml
  2. Download the Phoronix Text Suite

  3. Install the Test Suite

    sudo dpkg -i phoronix-test-suite_9.2.1_all.deb
  4. Install the Blender Benchmark

    phoronix-test-suite install blender
  5. Run the Blender Benchmark

    phoronix-test-suite benchmark blender
  6. Choose the Classroom Scene Benchmark

  7. Choose CPU-only

  8. Choose "n" when prompted save the results

  9. Re-enable the GNOME lock screen

    gsettings reset org.gnome.desktop.lockdown disable-lock-screen


Simply buying a 64-Core CPU doesn’t guarantee you’ll get the full 64 Cores worth of performance. To prevent throttling, Thelio Major uses a large duct to separate the CPU from the GPU and the heat that each generates. Copper piping draws heat away from the CPU. Fans then funnel hot air out the exhaust ports and bring in cool air to replace it.

With System76’s meticulously engineered thermal enhancements, you’ll get a clear picture of what 64 Cores can really do. That’s something most other computer manufacturers just can’t measure up against.
