A force d’affirmer que les retards d’Intel proviennent d’un d\u00e9faut de ma\u00eetrise de la technologie \u00e0 90 nanom\u00e8tres, ne passe-t-on pas \u00e0 c\u00f4t\u00e9 d’un probl\u00e8me plus d\u00e9licat ? <\/p>\n

Las! La rumeur sur la difficile ma\u00eetrise de la technologie \u00e0 90 nanom\u00e8tres finirait par le laisser entendre! Mais alors pourquoi les retards portent-ils sur le Pentium 4 Prescott et non sur le Celeron Prescott, alors que ce dernier utilise la m\u00eame technologie ?<\/p>\n

En effet, le Celeron Prescott est proche du Pentium 4, sauf son ‘cache’ L2 \u00e0 256Ko, tandis que son a\u00een\u00e9 embarque 1Mo de cache L2, et l’absence d’HyperThreading. Tous deux sont fabriqu\u00e9s en 90 nanom\u00e8tres et disposent d’un bus \u00e0 533MHz.<\/p>\n

Si Intel fabrique du Celeron Prescott, lui aussi en 90 nanom\u00e8tres, mais prend du retard sur les Pentium 4 Prescott, c’est donc ailleurs qu’il faut chercher la cause. Difficile d’\u00eatre renseign\u00e9 par Intel.<\/p>\n

Le site Xbit Laboratories<\/a> a \u00e9mis l’hypoth\u00e8se d’un probl\u00e8me li\u00e9 \u00e0 l’augmentation du ‘core-speed’ du Pentium 4 Prescott, donc de fr\u00e9quence. Une hypoth\u00e8se plausible, car le Pentium est beaucoup plus complexe que le Celeron. D’o\u00f9 l’\u00e9ventualit\u00e9 de probl\u00e8mes de surchauffe constituant d\u00e8s lors un d\u00e9faut majeur.<\/p>\n
