Data Changelog

Last updated: 2026-07-08

This page records changes to our hardware data. Because much of the launch data is unverified sample data, we track it openly here so you can judge how current it is.

Verification status

Sample entries needing verification: 134 of 151 hardware items. Each is flagged inside the tools until a human checks it against the manufacturer's official specification and records a verified date.

Change history

  1. 2026-07-08

    AMD/Intel web verification pass; +2 official-page confirmations (17 verified total)

    Affected data: cpus.json

    A 10-agent web team re-checked all remaining AMD/Intel entries against official vendor pages, each paired with the cached independent memory review. AMD's and Intel's sites blocked or timed out most automated fetches (AMD timeouts; Intel ARK HTTP 403), so most models received a strong two-source knowledge cross-check but no live official-page confirmation and remain needsVerification=true. Two AMD CPUs whose official amd.com model pages did load — Ryzen 9 7950X and Ryzen 9 7900X — are now confirmed and marked verified with their exact spec-page URLs. Total AI-verified entries: 17 (15 NVIDIA GPUs + 2 AMD CPUs). No figures required correction in this pass.

  2. 2026-07-08

    Multi-agent verification pass; 15 GPUs AI-verified against official pages

    Affected data: cpus.json, gpus.json

    A verification team (paired web + independent memory reviewers per family, plus power-delivery / guide-consistency / data-hygiene / PSU-sanity auditors) reviewed all 151 entries. Outcomes: RTX 50 series (7) and RTX 40 series (8) confirmed against official NVIDIA spec pages by two independent reviewers and marked needsVerification=false with the exact spec-page sourceUrl. One correction: Core i5-11600K peak 224->251W (conservative PL2). Connector encoding aligned to the reference/Founders-Edition input across the RTX 40 family (rtx-4070 and rtx-4060-ti set to 12V-2x6 to match siblings; notes cover partner 8-pin cards). Arc A380 given a single-8-pin reference encoding (retail cards ship a plug). Guide math and PSU-guidance audits found zero issues. Remaining entries stay needsVerification=true pending live official-page confirmation. See DATA_POLICY.md for what 'AI-assisted verification' means.

  3. 2026-07-08

    Dataset expansion round 3: 151 total entries (73 CPUs, 78 GPUs)

    Affected data: cpus.json (36 -> 73), gpus.json (38 -> 78), types.ts, en.json

    Added the remaining high-search used-market hardware: GeForce RTX 20/16/10 series (incl. GTX 1080/1070/1050 Ti, GT 1030), Radeon RX 6000 fill-in, RX 5000, Vega 64/56, RX 590/580/570, Intel Arc A-series, plus Ryzen 5000XT/5000G/4000/3000/2000 and Intel 12th/11th/10th/9th/8th gen CPUs. Introduced two new connector categories: 'pcie-6pin' and slot-powered cards (null connector, shown as 'None — powered by the PCIe slot alone'). All new entries ship needsVerification=true.

  4. 2026-07-08

    Major dataset expansion: +28 CPUs, +24 GPUs

    Affected data: cpus.json (8 -> 36), gpus.json (14 -> 38)

    Added previous-generation coverage: Ryzen 9000/7000/5000 and Intel Core Ultra 200S/14th/13th/12th gen CPUs; GeForce RTX 40/30 series, Radeon RX 7000/6000, and Intel Arc B-series GPUs. Figures are vendor-published limits, generated and independently cross-checked by two separate reviewers before inclusion (disagreements resolved to the conservative ceiling). All new entries remain needsVerification=true pending human verification against official spec pages. RX 6750 XT / 6700 XT connector counts recorded conservatively as two PCIe cables (reference 8-pin + 6-pin layout).

  5. 2026-07-07

    Initial sample dataset published

    Affected data: 8 CPUs, 14 GPUs, 6 monitor presets

    Seeded the launch dataset with current-generation retail parts and a few popular previous-generation cards. All hardware entries are conservative vendor-published limits and are flagged as needing human verification against official specification pages.

  6. 2026-07-07

    PSU sizing rules established

    Affected data: psuRules

    Set the headroom model (1.1x minimum floor; 1.25/1.35/1.45 comfort multipliers) and the retail PSU tier ladder used for rounding recommendations.
