Sempre pi\u00f9 dettagli sulla nuova architettura delle schede grafiche AMD Navi stanno emergendo. Come \u00e8 noto, essa rappresenter\u00e0 una nuova versione<\/a><\/noindex> dell'architettura Graphics Core Next (GCN), ampiamente utilizzata da tempo, ma secondo le ultime informazioni, subir\u00e0 significative modifiche. In particolare, nella nuova architettura sar\u00e0 corretta una seria carenza presente nelle versioni precedenti del GCN.<\/p>\n

\"Le<\/p>\n

\u00c8 apparso in rete pubblicata<\/a><\/noindex> uno schema del processore grafico Navi 10. Da quanto si evince, la potenza di calcolo del processore grafico sar\u00e0 suddivisa in otto blocchi shader (Shader engine), ciascuno dei quali conterr\u00e0 cinque blocchi di calcolo (Compute units, CU). Ricordiamo che ogni CU nell'architettura GCN ha 64 processori di flusso. Quindi, in totale, il Navi 10 avr\u00e0 2560 processori di flusso. Non male per un chip di fascia media.<\/p>\n

\"Le<\/p>\n

Le versioni precedenti dell'architettura GCN prevedevano la suddivisione delle unit\u00e0 di calcolo in quattro blocchi shader. Questa configurazione era presente, ad esempio, nel chip Hawaii Pro con gli stessi 2560 processori stream, ed \u00e8 rimasta la stessa nelle GPU Polaris e Vega. Proprio per questo motivo, le GPU AMD non potevano offrire pi\u00f9 di 64 blocchi di operazioni rasterizzate (ROP).<\/p>\n

\n<\/center><\/p>\n

Pertanto, la decisione di suddividere le GPU Navi in otto blocchi shader suscita speranze per un raddoppio del numero di blocchi di operazioni rasterizzate, portando il totale a 128. Ci\u00f2 dovrebbe ovviamente riflettersi positivamente sulle prestazioni della GPU, in particolare nei giochi.<\/p>\n
