CPU Dev Benchmarks

There are a lot of benchmarks out there for CPUs / GPUs, but I couldn’t find any real developement scenarios comparing different machines. I just got a new ryzen PC so I decide to create this benchmarks page comparing some machines I have access to.

It’s a simple timing of the compilation times for different projects.

Machines tested with

3900X: Ryzen 3900X 32GB DDR4@3600
8700K: I7-8700k 16GB DDR4@2400
7700T: HP Envy 27 - I7-7700T 16GB DDR4@2133
8550U: Huawei Matebook X Pro - i7-8550U, 16GB LPDDR3@2133

All tests have been executed 3 times and the final time is the average of those runs.

Cmd commands timed with:

@echo off
@setlocal

set start=%time%

:: Runs your command
cmd /c %*

set end=%time%
set options="tokens=1-4 delims=:.,"
for /f %options% %%a in ("%start%") do set start_h=%%a&set /a start_m=100%%b %% 100&set /a start_s=100%%c %% 100&set /a start_ms=100%%d %% 100
for /f %options% %%a in ("%end%") do set end_h=%%a&set /a end_m=100%%b %% 100&set /a end_s=100%%c %% 100&set /a end_ms=100%%d %% 100

set /a hours=%end_h%-%start_h%
set /a mins=%end_m%-%start_m%
set /a secs=%end_s%-%start_s%
set /a ms=%end_ms%-%start_ms%
if %ms% lss 0 set /a secs = %secs% - 1 & set /a ms = 100%ms%
if %secs% lss 0 set /a mins = %mins% - 1 & set /a secs = 60%secs%
if %mins% lss 0 set /a hours = %hours% - 1 & set /a mins = 60%mins%
if %hours% lss 0 set /a hours = 24%hours%
if 1%ms% lss 100 set ms=0%ms%

:: Mission accomplished
set /a totalsecs = %hours%*3600 + %mins%*60 + %secs%
echo command took %hours%:%mins%:%secs%.%ms% (%totalsecs%.%ms%s total)

Benchmark 1 - FFMPEG (FFmpeg for WinRT)

As some machines didn’t reach 100% procesor usage while compiling, I’ve also included the parallel compilation benchmark, where I ran two build instances at the same time. The total time is the average of those two compilations.

Benchmark 2 - UWP app (Release mode .net native toolchain x86|x64|arm)
