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…

Power-Performance Curves for CPUs launched on February 26, 2023 with 13 votes, #1,352 of 3,829 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.

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.

    The overall idea is to chart out the thousands of Mini PCs by benchmark and reveal the Pareto Front so you can get the most Compute per Dollar. Definitely a labor of love as I have a number of Mini PCs for my "homelab" (TrueNAS, piHole, Plex, basic stuff). It uses Gemini to extract specs from listings (since they're not often strongly categorized). Quick blog post here: https://luke.zip/posts/pareto-pcs/

    Research Hacker News, ArXiv & Google with Hierarchical Bayesian ModelsOct 2025 · sturdystatistics.com · ▲85

    Hi Hacker News! I’m a Bayesian statistician that has been working on applying hierarchical mixture models (originally developed for genomics) to structure text data, and in the process, used these models to build (what started as a personal) tool for conducting literature reviews and deep research. My literature review process starts with a broad search to find a few key papers/groups, and from there expands along their citation networks. I needed to conduct a few rounds of literature reviews during the course of my research and decided to build a tool to facilitate this process. The…
