Catalyst 8.12: Big Bang od ATI

i Zdroj: PCTuning.cz

Nová verze ovladačů, která je reakcí na Big Bang II od nVidie přináší podporu rychlého převodu videa přes GPU. Technologie ATI Stream umožnila „odemknout“ výpočetní možnosti Radeonů řady HD4800, 4600 a převádět tak videa do formátu H. 264 velmi rychle. Ovladače naopak neumí OpenCL 1.0 (Open Computing Language). Server CompterBase.de provedl již první testy a jak můžete vidět, grafické karty od společnosti ATI si nevedou vůbec špatně.

Nové ovladače také přinášejí nárůst výkonu v novějších hrách (Far Cry 2, Fallout 3, Stalker: Clear Sky a další). Zlepšení je očekáváno hlavně ve hře Far Cry 2, kde Radeony nepodávali optimální výkon.

edit: V 3DMark Vantage jsem s grafickou kartou HD 4870 X2 naměřil 0,8% nárůst výkonu.

edit: 11.12.2008: společnost AMD/ATI ohlásila podporu OpenCL 1.0
