Am observat cu stupoare ca exista Prescott 531. Acum sap sa vad diferentele dintre el si prescott 530.

Oricum, afirmatia mea ca nu exita Prescott 531 e putin gresita. Reformulez, "nu exista seria xx1 in 65nm Prescott" .

Gata, m-am lamurit.

Toata seria 5xx este facuta in 90nm. Cea mai importanta deosebire dintre 5xx si 5x1 este ca cele din urma stiu Intel® EM64T. Aici nu avem de-a face cu Cedar Mill. Only Prescott (my fault)

Toata seria 6x0 este facuta in 90nm. Chiar si 6x2. Tot Prescott. 6x2 sunt niste 6x0 cu VT (Virtualization Technology).

In sfarsit 6x1 este Cedar Mill , 65nm. Exista si 6x3, adica niste 6x1 cu VT.

5x0, 5x1, 6x0, 6x1, 6x2, 6x3 ruleaza toate la aceeasi frecventa data de x .

Acum puteti da drumul la flame :) .......  Glumesc. Am mai gresit ceva?

Ma uit intr-o lista cu procesoarele scoase de la Northwood incoace si acolo zice ca:
- P4 Prescott seria 6xx (3-3,8GHz) stie EM64T, EIST, 2MB L2, 90mm si atit (deci nu VT).
VT se regaseste in P4 Presler, aparut in Jan06, cu 4MB L2 si care nu are HT, si e pe 65mm. Inainte de asta, P4 nu a avut VT.

5x0, 5x1, 6x0, 6x1, 6x2, 6x3 ruleaza toate la aceeasi frecventa data de x .
Ca să nu fie confuzie:
x=2 -> 2.80 GHz
x=3 -> 3.00 GHz
x=4 -> 3.20 GHz
x=5 -> 3.40 GHz
x=6 -> 3.60 GHz
x=7 -> 3.80 GHz

Apoi, există şi modelele 5x0J, care au în plus o protecţie la atacurile de tip "buffer overflow": Execute Disable Bit.
Seria 5x1 are deasemenea această protecţie.

O altă jucărie de la Intel e modelul 524, care sfidează puţin regulile. Rulează la 3,06 Ghz în loc de 2,8, are Bus-ul de 533 Mhz, EM64T şi EDP.

O listă nu foarte concludentă.

Josephine, nu-i chiar aşa.
Pentium 662, Pentium 672.

Presler e seria 9xx, adică dual-core. :D Presler = 2xCedar Mill
Şi nu toate au VT.
