Prismark 0.2.0 (beta)

First public beta of Prismark, a CPU benchmark that measures your computer as it is configured, test by test, with no overall score.

Both downloads are portable: unpack and run, nothing to install.

Windows x86-64 — prismark-0.2.0-windows-x86_64.zip

Unzip anywhere and start prismark-gui.exe. Needs 64-bit Windows 10 or later. To record power, accept the offer to restart as administrator.

Linux x86-64 — prismark-0.2.0-linux-x86_64.tar.gz

Runs on Ubuntu 22.04 or later (or a distribution of the same age or newer), including a live USB session.

tar -xzf prismark-0.2.0-linux-x86_64.tar.gz
cd prismark-0.2.0-linux-x86_64
sudo chmod a+r /sys/class/powercap/intel-rapl:0/energy_uj   # optional: power readings, until reboot
./prismark-gui

What's in it

• Tests on all cores, on one core and for responsiveness, plus memory delay, timer punctuality and the gain from newer instructions (AVX2/AVX-512).
• Compile tests included in both packages: "Compiling code" (Clang built in) and "Full software build" (sources, Clang 19, CMake and Ninja shipped).
• Clock per core type and per CCX (P and E cores shown separately), and package power on Windows (admin) and Linux.
• Rankings against four measured reference systems: Ryzen 7 8845HS (plugged in and on battery), Core i5-1035G1 and Core i9-14900K. The 14900K is delidded and overclocked, and is the best of two runs.
• prismark command line in both packages (prismark help).

Beta: known limits

• The Linux desktop app was tested under X11; under Wayland, if the window misbehaves, start it with QT_QPA_PLATFORM=xcb ./prismark-gui.
• A full run takes about 30–40 minutes. Don't touch the keyboard or mouse during the tests marked as needing an idle computer.
• Results from 0.2.0 may not be comparable with later versions.
