Power-Performance Curves for CPUs
Hi HN! Following the release of the latest generation of CPUs by AMD and Intel with rather high power requirements and the corresponding uptake in interest of undervolting / power level adjustment, I was interested to find out in more detail how these CPU models would perform and compare at different power settings. However, it couldn't find an online source that would provide a satisfactory amount of data to be really useful to compare different models. So I took what data I could find to set up a Bayesian regression model. Find the results and more details on the linked page. Hope…
In plain words
Power-Performance Curves for CPUs is a tool that models how different CPU models from AMD and Intel perform at various power settings. It uses Bayesian regression to analyze performance data and enable comparisons across different processors, addressing a gap in available undervolting and power adjustment information. The resource helps users understand the trade-offs between power consumption and CPU performance for modern processors.

Hi HN! Following the release of the latest generation of CPUs by AMD and Intel with rather high power requirements and the corresponding uptake in interest of undervolting / power level adjustment, I was interested to find out in more detail how these CPU models would perform and compare at different power settings. However, it couldn't find an online source that would provide a satisfactory amount of data to be really useful to compare different models. So I took what data I could find to set up a Bayesian regression model. Find the results and more details on the linked page. Hope this is useful or of interest. Any feedback is welcome. Especially great would be if someone knows a source for or would be able and willing to contribute data for more CPU models (especially Intel 13th Gen.). PS.: Please not that I haven't been able to spend much time on optimizing the website.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
