Ναι , σαν το UT2003 / UT2004 , όπου οι ATi είναι πιο γρήγορες.

Το σηματάκι δεν σημαίνει τίποτα.

Χρήμα σημαίνει.

 

Για αυτό με την διαφορά στις high end κάρτες , μπορεί σε μερικά games να είναι πάνω κάτω 10-15fps , αλλά θα μου πείς πιάνουν 100+ fps , οπότε όποια και να πάρεις είσαι ok , αλλά σε κάποια άλλα η μια κάνει ψιλό-playable ένα game [ π.χ. το Perimeter σε 1024x768 με Med. Details ] , και η άλλη δεν το παίζει [ σε αυτό το π.χ. η ATi X800XT PE πιάνει μόλις 30fps ] [ ενώ η nV κάτω από 25 ]

Να το πάρουμε από την αρχή;

 

Ηyperthreading ή multithreading ή application stack είναι το ίδιο και το αυτό και ουσιαστική του χρησιμότητα είναι όταν σε ΕΝΑΝ επεξεργαστή θέλουμε να τρέξουμε περισσότερες της μία εφαρμογές ταυτόχρονα. Οι επεξεργαστές γραφικών εδώ και αιώνες δεν αποτελούνται από μια μονάδα ΜΟΝΟ αλλά από πολλαπλές και αυτό που εδώ πετάξατε σαν μαιντανό κάπου στην μέση είναι μέρος της επεξεργασίας των γραφικών εδώ και αρκετό καιρό, για αυτό τον λόγο οι επεξεργαστές γραφικών είναι κατά πολλές φορές πιο επαρκής και γρήγοροι στην επεξεργασία γραφικών από ότι ένας απλός επεξεργαστής.

 

Και για να το πάω ένα βήμα πιο μακριά οι σημερινές κάρτες εδώ και γενιές δεν έχουν πλέον "pipelines" αλλά κανάλια SIMD (single instruction multiple data). Oι πιο πρόσφατες καρτούλες (από την R300 και πλέον) έχουν MIMD (multiple instruction multiple data) κανάλια και για να εξοικονομήσω χρόνο, σας αφήνω να ξανασκεφτείτε και οι 2 τι ακριβώς είπατε.....
