yesbenchmark 1.0.0

The only benchmark tool on the block crazy enough to abuse the UNIX yes command to test your CPU

yesBenchMark

yesBenchMark is a crazy tool for benchmarking the CPU in UNIX & UNIX-like systems. It abuses the yes command to load the CPU and measures CPU utilization, speed, and compute.

Features

• Extremely tiny & light
• Can run on extremely old hardware (OS X 10.4 Tiger is oldest it can run on of all the stuff out there, with a modest G3)
• Can do a ton of different modes, varying in load from light to extremely punishing to see how far you can push your CPU:
  • time - See how much the CPU can output in 30 & 60 seconds respectively in a single thread (yes)
  • multicore - Multi-core version of the time benchmark
  • freq - Bench how fast your CPU core can turbo
  • multi-freq - Multi-core version of freq benchmark
  • stress - See how little of the total CPU a single thread can use, also includes a stability measurement
  • compute - Check how long it takes the CPU to compute 27,000,000,000 hunks of data (each hunk is a single y\n)
  • compute-xt - compute benchmark but with 10x the hunks
• Written in Python & extremely portable, so runs almost anywhere
• Probably one of the most practical benchmarks out there - measures CPU load, CPU frequency, and other things encouuntered in day-to-day workloads; none of the shenanigans that most tools use to grade your CPU's performance

Usage

Usage: yesbenchmark [options]
Options:
  --help, -h          Show this help message
  --mode=MODE         Run specific mode of benchmark

Modes:
all                   Run all modes of benchmarks
time                  Run time-bound benchmark
multicore             Run time-bound benchmark for all cores
freq                  Run frequency-bound benchmark
multi-freq            Run multi-core version of frequency-bound benchmark
stress                Run stress/utilization benchmark
compute               Run compute benchmark (time taken depends on CPU speed)
compute-xt            Run a more extreme version of compute benchmark

Well that is...all the capabilities of the program. We recommend the compute mode for most people.

Scores for reference (performance is compute & extreme is compute-xt):

M1 Max with 8 P-cores & 2 E-cores (10 cores total):

• P70,363 → performance mode
• X685 → extreme mode

i7-2600 with 8 cores:

• P55,609 → performance mode
• X557 → extreme mode

G5 with 1 core:

• P572 → performance mode
• {untested} → extreme mode (would take forever on my iMac G5 and overheat it)

Note: Do NOT run the program with zero arguments unless you want to run ALL benchmarks except the compute-xt one. This will take a long time and likely overheat your computer.

Installation

Requirements:

• Python 3.8 or later (we don't test for older, probably works down to 3.6)
• OS X 10.5 Leopard or later (if too old to be supported by Homebrew, please use Tigerbrew to install Python 3.10) or Linux 3.2 or later (BSDs may be supported at a later time when I have time to spin up one in a virtual machine)

To install yesBenchMark via pip:

pip install yesbenchmark

Or if you have cloned the repo for development (note that this will also allow you to edit the src code without re-installing for ease):

pip install -e .

Compiling and installing as a binary

Requirements:

• The above requirements
• If macOS, an Intel x86_64 CPU or better
• MacOSX 10.9 or later if on Mac

To compile:

python3 compile.py

After that, just copy the binary in dist out and into a directory in your PATH.
