Basically the base (not turbo boosted) CPU Frequency is amount of TSC Increments per one second.

This code will read latency and throughput of the CPU instructions (Draft)

This code will read memory at different sizes and measure bandwidth

The easiest way to print integer and floating-point values from Assembly Code to the Console

I ran my own experiments to better understand how Hyper-Threading works internally on Windows, using hand-written assembly benchmarks — from single-register multiplications to SHA-256 hashing.

llvm-mca is a performance analysis tool to statically measure the performance of machine code in a specific CPU.

I just encountered an interesting exception in LabVIEW when the Median Filter was called for a float image containing a NaN value. It works as expected for small images, but I found one that caused a crash.

If you have a dual-socket CPU, each socket may have dedicated RAM assigned to it. This can lead to performance penalties when a processor accesses memory from the “wrong” memory bank. Below is a simple benchmark and an explanation of how to utilize the full bandwidth properly.

Installation of gcc and clang is not very complicated, but there are some issues in corporate environment which I would like to note.

To get DeepSeek running on your PC you will need enough RAM, and it is quite easy with llama.cpp. Below step by step guide and results.

Sometimes we need to check MD5 or SHA256 checksums for downloaded files. An easiest way:

certutil -hashfile <FILE> MD5

or with PowerShell:

Get-FileHash <FILE> -Algorithm SHA256

In attempt to install winget on Windowss 11 LTSC as recommended by Microsoft I’ve got error message. Below the simple workaround

Recently upgraded CPU in my ancient laptop from i7-4800MQ to i7-4940MX, which is Extreme Edition, and need legacy Intel Extreme Tuning Utility, version XTUSetup 6.5.1.360 is compatible.

It is necessary to set Working Directory, otherwise ConEmu will not start Far Manager.

The AutoHotkey script for Win+F:

#Requires AutoHotkey v2.0

#f::
{
    SetWorkingDir("C:\Program Files\ConEmu")
    Run ("C:\Program Files\ConEmu\ConEmu64.exe")
}

Today I noticed that my computer was slower than usual. A brief investigation revealed that PowerLauncher.exe was causing other running MSI installers to fail when setting up shortcuts.
