Placas base y Barton

[BlkHeart]

Seran compatibles las placas actuales con los nuevos micros AMD Barton ??

Y… no huele un poco a chamusquina que le metan al barton un 600+ ? a la misma frecuencia que un Tbred ?? esperemos que sea verdad, aunque todo esto se vera en los bech.

Saludos.

Athlon XP (Barton) Rating: Learn the New Formula!
Posted 6/29/02 at 7:16 am by Rat

This Chinese site (the same one that shared the confidential ATI slides with us last week (see this news story) shared with us some info, which allows us to derive a new formula and to calculate the rating of Athlon XP processors based on 0.13micron Barton core (it is none other but a Thoroughbred with 512KB L2 cache, which will be manufactured by UMC only and the mass production of which is planned for Q4 2002). Here is this formula:

Rating =3 x Frequency/2 + 100
The reverse formula is also very easy to derive, as you may see:

Frequency =2 x Rating/3 - 66
These formulas are very similar to those used to calculate the rating of Athlon XP processors on Thoroughbred and Palomino core (Rating = 3 x Frequency/2 – 500 and Frequency = 2 x Rating/3 +333, see this news story). Now you will understand why:

Frequency Palomino
(0.18micron, L2=256KB) Thoroughbred
(0.13micron, L2=256KB) Barton
(0.13micron, L2=512KB)
1.33GHz Athlon XP 1500+ - -
1.4GHz Athlon XP 1600+ - -
1.46GHz Athlon XP 1700+ Athlon XP 1700+ -
1.53GHz Athlon XP 1800+ Athlon XP 1800+ -
1.6GHz Athlon XP 1900+ Athlon XP 1900+ -
1.67GHz Athlon XP 2000+ Athlon XP 2000+ Athlon XP 2600+
1.73GHz Athlon XP 2100+ Athlon XP 2100+ Athlon XP 2700+
1.8GHz Athlon XP 2200+ Athlon XP 2200+ Athlon XP 2800+
1.87GHz - Athlon XP 2300+ Athlon XP 2900+
1.93GHz - Athlon XP 2400+ Athlon XP 3000+
2GHz - Athlon XP 2500+ Athlon XP 3100+

As you see, the doubling of the L2 cache size provides a 600+ increase of the AMD rating. So, the rating of Athlon XP (Barton) can be obtained from Athlon XP (Palomino or Thoroughbred) working at the same frequency by simply adding these "pluses" to the rating of the latter.

A mi tambien me parece mucho rendimiento por 512K de cache, pero bueno, esperemos que sea cierto.

Sobre lo de la compatibilidad, pues, en principio, no deberiamos tener problemas, se supone que es el mismo chip que el actual, pero con mas cache, por lo qu elas placas que ya soportan el nuevo de 0.13 pues con otra actualizacion de bios, listo.
