5g IQ sample datasets

5g IQ sample datasets

I've been pretty interested in learning more about the 5g NR protocol and some of the physical layer processing. Does anyone know a good available 5g dataset I could use to experiment and practice?

What's wrong with using the Arduino …

What's wrong with using the Arduino framework in industry?

I do "advanced" Arduino programming, in which I create my own .cpp files and .h files and include them in my main sketch, and use VS Code with the Arduino plugin. It works great, and I can apply the same code to multiple different boards.

Now, what's the problem with using the Arduino framework in a commercial product? I understand that it probably uses more memory and storage than desired, but how much more? Why does everyone shit on it, and would something like Platformio be better?

Disclaimer: Voodoo2-SLi on Reddit and Leonidas on 3DCenter are the same person. So, I write these reviews by myself for 3DCenter and translate the performance tables for Reddit by myself. No copy and paste of other people's work.

AMD Ryzen 7 9800X3D Meta Review: …

AMD Ryzen 7 9800X3D Meta Review: 19 launch reviews compared

- compilation of 19 launch reviews with ~4720 application benchmarks & ~1640 gaming benchmarks
- stock performance on default power limits, no overclocking, memory speeds explained here
- only gaming benchmarks for real games compiled, not included any 3DMark & Unigine benchmarks
- gaming benchmarks strictly at CPU limited settings, mostly at 720p or 1080p 1% min/99th percentile
- power consumption is strictly for the CPU (package) only, no whole system consumption
- geometric mean in all cases
- performance average is (moderate) weighted in favor of reviews with more benchmarks
- tables are sometimes very wide, the last column to the right is the 9800X3D at 100%
- retailer prices according to Geizhals (Germany, on Nov 10, incl. 19% VAT) and Newegg (USA, on Nov 10) for immediately available offers
- performance results as a graph
- for the full results and more explanations check 3DCenter's Ryzen 7 9800X3D Launch Analysis
- TLDR: on average, 9800X3D brings +22.2% more application performance and +11.5% more gaming performance over 7800X3D
