Local Hardware Frontier

Start with LOCAL_HARDWARE_FRONTIER.md. It is the readable writeup: prose and generated charts only. Raw CSVs, item JSON, schema, and regeneration code stay as adjacent files instead of being embedded in the writeup.

This folder also keeps the separate item JSON files, CSVs, PNG/SVG charts, gallery, schema, and scripts for editing and regeneration.

Regenerate

From this folder:

python3 -m venv .venv

pip install -r requirements.txt
python scripts/validate_items.py
python scripts/generate_graphs.py
python scripts/build_self_contained_md.py
python scripts/build_static_space.py

The validator checks item-file shape, price bands, year ranges, source URLs, bandwidth-source pairing, aggregate-bandwidth notes, duplicate generated rows, non-overlapping price histories, and extracted memory-price rows. The graph script refreshes generated CSVs, charts/, gallery/all_price_band_charts.html, README_methodology.txt, and local_hardware_frontier_artifacts.zip. The writeup builder refreshes LOCAL_HARDWARE_FRONTIER.md without embedding raw data. The Space builder refreshes the static space/ bundle.

Scope

The data tracks maximum accelerator-accessible memory in one machine from 2020 to 2026 across Apple, NVIDIA, and AMD, grouped by complete-machine price band. It distinguishes unified/coherent memory, single-GPU VRAM, and aggregate multi-GPU VRAM. Bandwidth is plotted only from explicit item JSON values; missing bandwidth is left blank rather than inferred.

price_per_memory_gb in data/verified_system_catalog.csv is the complete configured machine price divided by accelerator-accessible memory. data/memory_price_per_gb.csv is different: it is the extracted GPU/card price or same-device memory upgrade delta divided by the priced memory amount.
