So, I decided to take into account the performance of Athlon 64 and P4 in various applications and I have normalized the results. Of course, Athlon will still get beat in Video/Audio encoding and P4 will still trail in most games. But my overall "Enhanced Athlon 64 Rating" gives a better overall view. A more realistic view based ona wide range of applications.

<b>Here is the maths…</b>

You need these Athlon 64 informations : Speed, Cache Size and Socket Type.

X = <font color=red>Speed / 100</font color=red>

Y = Cache Size (in KB) / 512

If Socket = 754 then Z = -1

If Socket = 939 then Z = 1

If Socket = 940 then Z = 0

<font color=red>If Speed >= 2.4GHz then S = 1 else S = 0</font color=red>

Enhanced Athlon 64 Rating = (X + Y + Z <font color=red>+ S</font color=red> + 9) * 100

9 is the offset to compensate Athlon 64 lower speed.

<font color=red>"S" is needed for the non-linear scaling of performance vs speed.</font color=red>

Here is an example of this equation :

Athlon 64 3200+ (S754/1Megs)

X = <b>2000</b>/100 = 20

Y = <b>1024</b>/512 = 2

Z = -1 for <b>S754</b>

S = 0 for <b>2.0GHz</b>

X + Y + Z + S + 9 = 30

30 * 100 = 3000+

So the Athlon 64 3200+ lost 200 point in this new rating, but overall, this Athlon 64 would be a better P4C/E 3.0GHz competitor. As I stated before, the A64 would crush the P4 in games, but it would not get that badly beatin by the P4 in other disciplines where the P4C/E shines.

With this "Enhanced Rating", the Athlon 64 rating move from 2800+/3800+ to 2700+/3600+. Overall there is no big change, just a little correction to some overated Athlon 64 (see 3500+). By the way, you can calculate the Athlon FX-53 rating with my equation. It can be compared to a 3700+.

<font color=red>UPDATES :

- I forget the "S" in my first post.

- I changed a bit the way to calculate the X. I know based it on speed instead of the multiplier, this helps evaluate the rating of overclocked Athlon 64. The only thing I need to evaluate now, is how the FSB overclock affect the overall rating, but I would need testing and overclocking numbers to figure this out. I don't think it impact the overall rating by much, but I know it impact it a bit.</font color=red>
