About this data

Highest chess rating ever achieved by computers
Chess ability is measured with the Elo rating system, which is calculated based on game results. A higher rating indicates that a player is more likely to win a game.

Sources and processing

This data is based on the following sources

This dataset provides a historical record of the highest ELO-rated chess engines from 1985 to 2022. The data for the years 1985 through 2019 was sourced from Chess.com, with the primary data originating from the Swedish Computer Chess Association (SSDF). The compilation of this segment involved manual extraction from video content to identify the chess engine with the highest ELO rating for each year, due to the unavailability of the data in any other format.

For the years after 2019, the data was obtained directly from the SSDF, with each year's highest ELO-rated chess engine recorded as a separate data point. These data points are available through archived links of the SSDF's website.

The 2020 data point can be found here. The 2021 data point is documented here. The 2022 data point is accessible here. The 2023 data point is accessible here

This dataset provides an objective overview of the progression of chess engine performance over the years, offering valuable insights for research and analysis in the field of computer chess and artificial intelligence.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
