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:

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.
