About my general purpose benchmark

zBenchmark is a general purpose benchmark that I wrote in C++ and which uses the Qt 6 library to provide a GUI.

I intended it to mainly run on Linux but, because both C++ and Qt are platform-agnostic, it could potentially run on Windows and MacOS as well.

I wrote the assembly language code for memory bandwidth measurements that requires the Unix ABI (application binary interface), so Windows at least will fall back on C code for that.

A single combined score

zBenchmark provides a single combined score to indicate the overall performance of your system, which is simply a sum of all the individual scores from the tests it performs.

The standard against which your system is compared, and which naturally has score of 1.0, is the dual-core Core i5 4278U that if found in the 2014 Macbook Pro running 64-bit Debian at 3.1 GHz (CPU governor: performance).

What tests does it perform?

Currently zBenchmark measures the performance of each of the following:

Download

zBenchmark 0.35

To compile it:

• Run ./configure
• Run ./install.sh
• Finally ./zBenchmark

Results

The reference system was previously the Raspberry Pi 4b however I sold mine, so for 0.35 the reference is the 2014 Macbook Pro, which has a Core i5-4278U and 8GB of DDR3L-1600 dynamic RAM.

iOS

I wrote a very similar benchmark app of the same name for iOS and it is in the App Store here.
