Nvidia Turing: nové technologie pro chytřejší rendering | Kapitola 8
Seznam kapitol
Dnešním dnem končí embargo na detaily k nové architektuře Turing a podrobnosti o nových funkcích, které karty nabízejí. Asi jen s málokterou premiérou za celou dobu historie grafických 3D akcelerátorů představili výrobci karet tolik nových technologií najednou.
