AMD confusion

[Grovebaby]

I'm getting a little confused about AMD designations. Are there 2 types of athlon Xp's. I see thoroughbred sometimes. Is this a different chip?

 

[WobbleWobble]

Thoroughbred is the older core of the AthlonXP CPU and has 333MHz FSB and 256KB L2 cache.

The newer core is Barton which can have 333MHz or 400MHz FSB and 512KB cache.

They both have the same Athlon XP name but they are slightly different chips. They both work the same though, but at the same speed, the Barton is generally slightly faster. AMD has rated accordingly using the XP numbers such as XP2400+ and XP2500+.

The XP2400+ is based on the Throughbred and the XP2500+ is based on the Barton. Even though the XP2400+ is clocked slightly higher, AMD thinks the larger cache on the Barton makes it slightly faster than the XP2400+ hence giving it the XP2500+ rating.

Theres also the non-Tbred Athlon XPs

AthlonXP Palomino core - 1.750 volts, 256k L2 cache, 266 Mhz bus... XP1600-XP2100
AthlonXP Thoroughbred A core - 1.650 volts, 256k L2 cache, 266 Mhz bus... XP1700-XP2200
AthlonXP Thoroughbred B core - 1.5-1.65 volts, 256k L2 cache, 266 or 333 Mhz bus... XP1700-XP2800
AthlonXP Barton core - 1.65 volts, 512k L2 cache, 333 or 400 Mhz bus... XP2500-XP3200

Decided to be more thorough in the models since they overlap...

Palomino
266 Mhz bus - XP1600, XP1700, XP1800, XP1900, XP2000, XP2100

T-Bred A
266 Mhz bus - XP1700, XP1800, XP1900, XP2000, XP2100, XP2200

T-Bred B
266 Mhz bus - XP1700, XP1800, XP1900, XP2000, XP2100, XP2200, XP2400, XP2600
333 Mhz bus - XP2600, XP2700, XP2800

Barton
333 Mhz bus - XP2500, XP2800, XP3000
400 Mhz bus - XP3200, and possibly lower ones in the near future

Nice post Jeff.

Thanks, I just wish I could use one of the Courier fonts on here to make it look more organized and easy to read, oh well.

Based on the results of my XP1700 Palomino, you'll be lucky to get 66 more Mhz out of it.

And just to add to the confusion, we now have Athlon FX or 'Thornton', which is a Barton core with 256K cache.

Not yet we don't... and that will be easier to differentiate because it will be manufactured using the SOI processed they're using for the Athlon-64's
