Le site américain X-bit labs vient de publier sur ses pages un test très intéressant du processeur AMD Phenom II X4 920 cadencé à une f’réquence de 2.8 GHz. Il fonctionne sur un socket AM2+ (940) et est gravé en 45nm. Ce confrère a donc eu l’opportunité de recevoir le haut de gamme du processeur Phenom II X4 940 Black Edition pour vérifier si son petit frère Phenom II X4 920 est limité niveau overcloking, n’appartenant pas pour sa part à la gamme « Black Edition ». « Phenom II X4 processors didn’t bring the desktop performance to any revolutionary heights. Unfortunately, even new manufacturing process doesn’t let AMD design CPUs that could successfully compete against Intel solutions in all price segments. And although the clock frequencies of the new AMD processors increased significantly, their performance turned out limited by the Stars (K10) microarchitecture potential, because it boasts lower IPC than the current Intel microarchitecture. Phenom II X4 920 we have just discussed is a great illustration to everything we have just said. At its nominal 2.8 GHz it can only compete against Core 2 Quad running at 2.4 – 2.5 GHz frequencies. Only smart pricing strategy helps AMD here: they positioned Phenom II X4 920 in such a way that it turns out a little better than the identically priced Core 2 Quad models. »
