The SSDF list is one of the only [[statistically significant]] measures of [[chess engine]] strength, especially compared to tournaments, because it incorporates the results of thousands of games played on standard hardware at tournament time controls. The list reports not only absolute rating, but also [[error bar]]s, winning percentages, and recorded moves of played games.

The SSDF's current testing platform includes an AMD Ryzen 7 1800X 8-Core 3.6 GHz with 16 GB of RAM-memory and a 64-bit operating system. On this platform they have chosen to add the 6 piece Syzygy endgame database, installed on SSD, for the programs that are able to use it. From 1984 to 20192020, the SSDF top program increased by 18981942 points, an average of 54 points per year.
