Svenska schackdatorföreningen

La Svenska schackdatorföreningen (SSDF) è un'associazione svedese dedita ai software scacchistici. Associazione di natura non commerciale, tra le sue attività la SSDF testa software o computer integrati per il gioco degli scacchi, redigendo una classifica. Il rating SSDF è una delle prime e storicamente più significative rilevazioni statistiche della forza di gioco dei motori scacchistici, perché comprende i risultati di migliaia di partite giocate su hardware standard e con tempo regolamentato. Non riporta solo i rating, ma anche barre di errore, percentuale di vittorie, mosse registrate delle partite giocate.

A metà anni duemila la lista è stata oggetto di critica in quanto i computer usati erano piuttosto lenti e datati rispetto all'evoluzione dell'hardware commerciale (256 MB RAM, processore singolo Athlon 1.2 GHz), il che limitava le prestazioni dei motori in termini di forza assoluta. Nel 2008 la SSDF è passata ad una piattaforma di test rinnovata, con processore Intel Core 2 Quad 6600 2.4 GHz, 2 GB di RAM e sistema operativo a 64 bit. Nello stesso anno, il rating massimo ha subito una improvvisa impennata, passando da 2935 a 3238. Nel 2017 l'hardware è stato rinnovato, con processore AMD Ryzen 7 1800X 8-Core 3.6 GHz, 16 GB di RAM, sistema operativo a 64 bit, e tablebase Syzygy a 6 pezzi installate su SSD.

Il rating SSDF si evolve indipendentemente e non è comparabile direttamente con altre classifiche, come l'Elo FIDE o altre classifiche di motori.
