Fast Memory Copying in C#/.NET (Cache, AVX, Threads, Unsafe, Alternatives)

Numerous copy routine implementations are readily available in .NET. If I were to simply list them alongside a few benchmark numbers and charts, it wouldn’t make for a very interesting article.

⚠️ What if I told you upfront that none of these routines is designed to be the absolute fastest?

If you’re interested in a basic comparison, I recommend checking out this article here on dev.to: What is the best way to copy an array? or a more detailed, older comparison: High performance memcpy gotchas in C#.

Zen5 and C#

Zen 5 landed with a bit of controversy, but anyone Who was paying any attention to the real results wasn’t disappointed. Benchmarks done using more mature OSes (like Linux and Win10) and professional software shown its strengths. But hey, why should we trust just any 3rd party data if we can make a test by ourselves? I used Ryzen 9950x today and a bit of code to get things going.

Performance on Peter Truchly
