AMD Athlon XP processor family is the successor to the Athlon CPU family. Palomino, the first Athlon XP core, had a few improvements over the previous Athlon core:
  • Full set of SSE instructions
  • Palomino core added a data prefetch mechanism.
  • Increased the size of the Translation Look-aside Buffer.

All Athlon XP Palomino CPUs had 266 MHz bus speed, and were manufactured using 0.18 micron technology.

Next revision of Athlon XP core, called Thoroughbred, was manufactured on newer 0.13 micron technology, and as a result, had smaller die size and lower power dissipation than the Palomino core. Bus speed of some Thoroughbred processors was increased to 333 MHz.

Bus speed of Athlon XP family was increased even further with the introduction of Barton core. In addition to faster bus speed the Barton core also had twice as much L2 cache memory - 512 KB. Athlon XP Barton CPUs were manufactured on the 0.13 micron process.

Thorton, the last Athlon XP core, was the same as the Barton core with L2 cache size slashed in half - from 512 KB to 256 KB.

Starting Athlon XP family, all AMD processors were marked with rated speed. Please see AMD Athlon XP identification page for relationship between rated speed and actual speed of AMD Athlon XP microprocessors.

Use the filter below to display microprocessors that have specific feature(s) incorporated:

Production microprocessors

AMD Athlon XP 1500+ was the slowest production Athlon XP processor. The 1500+ was clocked internally at 1.333 GHz, that is 67 MHz lower than the fastest Athlon processor with Thunderbird core. Depending on the application the Athlon XP 1500+ could be a little slower than the Athlon Thunderbird 1.4 GHz, or, as in the case of SSE-enabled applications, up to 20% faster. On average the 1500+ was a few percent faster than the Athlon Thunderbird 1.4 GHz / 266 Mhz FSB.
AMD Athlon XP 1600+ - AX1600DMT3C
1600 MHz (rated), 1400 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)

All Athlon XP microprocessors had rated speed. According to AMD, the rated speed could be used to estimate processor's performance relative to Athlon Thunderbird processors. When compared to Pentium 4 Williamette processors, the XP's rated speed was about 200 - 300 MHz lower than the speed of equally performing Pentium 4. For example, this AMD Athlon XP 1600+ was comparable to Pentium 4 1.8 or 1.9 GHz processors, and it was not uncommon for the XP 1600+ to outperform Pentium 4 Williamette 2 GHz in some benchmarks.
AMD Athlon XP 1800+ - AX1800DMT3C
1800 MHz (rated), 1533 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 1800+ - AXDA1800DLT3C
1800 MHz (rated), 1533 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 1800+ - AXDA1800DUT3C
1800 MHz (rated), 1533 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 1900+ - AX1900DMT3C
1900 MHz (rated), 1600 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 2000+ - AX2000DMT3C
2000 MHz (rated), 1667 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)

Performance of Pentium 4 microprocessors was improved with the introduction of Northwood core. The Northwood core had twice as much L2 cache memory when compared to older Williamette core, as a result performance of the Northwood processors was better than that of Williamette CPUs, but still this was not sufficient to outrun AMD Athlon XP 2000+. The 2000+ was almost always faster than the Pentium 4 2A GHz, and often as fast as Pentium 4 2.2 GHz.
AMD Athlon XP 2100+ - AXDA2100DUT3C
2100 MHz (rated), 1733 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 2200+ - AXDA2200DKV3C
2200 MHz (rated), 1800 MHz (real)
266 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
AMD Athlon XP 2400+ - AXDA2400DKV3C
Athlon XP 2400+ is not the fastest CPU with Thoroughbred core, but it is still a good choice to consider if your motherboard doesn't support Barton and Thorton cores. The primary reason for this is that at this moment (May 2006) the fastest Athlon XP rated 2600 MHz is difficult to find, and it's way overpriced. As its rating suggests the Athlon XP 2400 on average is on par with Pentium 4 2.4 GHZ (depends on application), and only 5% or less slower than Athlon XP 2600+.
AMD Athlon XP 2500+ - AXDA2500DKV4D
2500 MHz (rated), 1833 MHz (real)
333 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
Athlon XP 2600+ is the fastest Athlon XP processor with Thoroughbred core and with 266 MHz FSB. This is usually the best processor upgrade for older motherboards that don't support newer Thorton and Barton cores. Be warned though that this and other "best upgrades" processors are in high demand and sometimes are difficult to find, hence they are usually overpriced.
It is very likely that all processors with this part number are fakes. There are no known genuine AMD AXDC2600DKV3C microprocessors. Fake Athlon XP 2600+ processors with a Thorton core can be easily recognized from their stepping code/date code markings - these markings are located below the part number on the top of the CPU. Stepping codes of fake Thorton processors belong to Thoroughbred core. For example, many fake 2600+ Thorton CPUs have stepping codes JIUHB and KIUHB.
Athlon XP 2600+ AXDA2600DKV3D has the same 2600 MHz rating as AXDA2600DKV3C, but it differs from it by having faster 333 MHz Front-Side Bus. One of mistakes people sometimes make is buying this processor instead of AXDA2600DKV3C to upgrade motherboards that do not support 333 MHz FSB. While this processor may run in motherboards with 266 MHz FSB, due to a fact that the processor has locked clock multiplier it will run internally at 1666 MHz, or about as fast as Athlon XP 2000+.
AMD Athlon XP 2800+ - AXDA2800DKV4D
2800 MHz (rated), 2083 MHz (real)
333 MHz bus speed
Staggered organic PGA (Socket A/Socket 462)
Athlon XP 3000+ was introduced simultaneously with new Athlon XP Barton core. Main new feature of this core is 512 KB level 2 cache, which is twice as large as L2 cache on all previously released XP microprocessors. Bigger L2 cache improved CPU performance by up to 10% - this allowed AMD increase processor rating to 3000 MHz while keeping internal CPU frequency lower than on Athlon XP 2800+ AXDA2800DKV3D.
AMD Athlon XP 3200+ - AXDA3200DKV4E
Athlon XP 3200+ is the fastest AMD processor for socket A (462). This processor has Barton core with 512 KB level 2 cache. It is one of a few socket A CPUs that support 400 MHz Front Side Bus. This processor is the best upgrade option for socket A motherboards that support it, though it does not have the best price/performance ratio. Being the fastest socket A (462) processor, it is probably one of the most expensive socket A microprocessors at the moment. To save money you may consider upgrading to Athlon XP 3000+ instead - it's only a few percent slower than the 3200+.

Matt - You should be able to upgrade to the fastest Athlon XP CPU with the same native maximum bus speed as your up-to-date BIOS can accommodate. Be that: 100/200, 133/266, 167/333, 200/400. You will find used Athlon XPs of almost all MHz/FSB combinations at eBay. Know what you want. Check MB and BIOS compatability in advance to see what variety of CPUs you have open to you. I'm over there bidding on some Athlon XPs right now that are the fastest that I'm really sure will work with my mainboard. Some there are even brand new if you really insist on that. Happy shopping to you!

First, what an incredibly informative and well done site. Clearly a "labor of love". GOOD JOB!

I have TWO Athlon AXDA2400's.
One is stepping code AIXIB (though it REALLY looks like aixJb, is that possible?) and the other is AIXHB.

The numbers that follow those designations are different also.

The question is: By the numbers on the chip is it possible to tell which is the "better" processor? Are there other numbers that would guide one?

I have two systems, very similar, but one gets the heavier use and if there is any difference I'd like to know.

THANKS in advance!

Response: Performance should be the same or almost the same. Compare CPU temperatures and use cooler CPU for the system with heavier load.

Don't Bother Trying
locked: All week 43 (0343) to 46 Bartons and Thoroughbreds and most (but not all) post week 46 Bartons and Durons and:

AQZEA 0338

AQXCA 0340


AQXFA 0339

AQYFA 0342


AQZFA 0342 TPMW and UPMW (multiple confirmations of both locked and unlocked chips)


Thoroughbred JIXIB 0339
Thoroughbred AIXHB 0340 UPMW
Thoroughbred AIXHB 0341 SPMW

Most made before week 35 and:

AQXFA 0340 MPMW and TPMW and UPMW and VPMW
AQZFA 0342 TPMW and UPMW (multiple confirmations of both locked and unlocked chips)

You see there is no stepping or week pattern, the only way to increase your chances is to try to get a pre week 35 Barton...

Locked & Unlocked AMD cpu's (b)

The so called Super unlock:

Basically, the method involves modding of the locked chips.

'PowerNow' feature allows voltage and multiplier changes in order to preserve battery life.

So if you have motherboard/chipset/BIOS support for PowerNow which not all boards do, nForce2 does not, you can use this feature on locked desktop CPUs.

You also need to boot into Windows with your locked multiplier and the FSB with which you can boot into Windows but you cannot change the FSB inside Windows, only the multiplier. Ironically, you can change the FSB too inside Windows with nForce2s but they have no PowerNow feature so it's of no use with super locked chips.
"Are there any hidden multiplier pins from the NC, VCC, VSS pins?"...................

The main idea is to see

1. Whether there are some VCC or VSS pins, measured from VSS, have large resistance, say, > 100 ohm. Normal VCC to VSS should be much smaller, and of course normal VSS to VSS should be zero.

2. Whether there are some NC pins, measured from VSS, have relatively small resistance, say, 10 M ohm.<

3. All resistance measured from VSS is sufficient, at least for the first trial.

4. In principle, ONLY measuring VCC, VSS and NC pins from VSS is sufficient. But if one can find someone to help, may well just measuring every pins and put the resistance number from VSS in the pin layout map and analyse them after the measurement.

AMD pin layout map, on Page 55

If suspecting there are some hidden pins (not specified in data sheet) among the
- NC pin group, or
- VCC pin group, or
- VSS pin group,
one can make a resistance map or table of each pin to VSS, and look for difference.

With a probe of a DMM connected to VSS, measure the resistance of each pin to VSS, and make a table. Then compare the resistance table to the pin table. One may want to measure each pin twice with the polarity reversed.

It should not be too difficult to do, especially if one can find a helper to write down the numbers while doing the measurement.

If a pin can be measured in 4 sec, a single pass of 478 pins would take about 32 minutes. Two pass would be about an hour.

If there is/are multiplier controlling pin(s) hidden among these NC, VCC, VSS pins, the resistance of that pin(s) would stand out differently from the other regular NC, VCC, VSS pins.
- If a pin is not a VCC pin or a VSS pin, and if it goes to the input of logic gates, or FET terminals, even if there is pullup or pulldown impedance, would be >> 10 ohm.
- If a NC pin turned out to be not NC, then the resistance would be much smaller than 10M ohm.

Locked & Unlocked AMD cpu's "Spooky!"

2007-02-15 19:11:36
Posted by: Joker13

Okay, here's the scoop on the possible existence of a second set of

pins. I have spent the past three evenings ohming the 5 known BP_FID

pins on my unlocked Barton to all the other pins on the bottom and

sadly, though not unexpectedly, I must report that none of the other

pins, regardless of claimed function, be that Vss, Vcc, N/C, etc, are

connected to them.

Now, here's where it gets "creepy". I eventually snapped and did

something I never dreamed I would do. On the Locked Barton, I heated

the core with a micro hydrogen flame torch, to keep the heat locallized

to the core until the sealant around the edge softened, as well as all

the solder dots, be they bismuth, indium, or whatever low temperature

metal AMD uses, melted. I then lifted the core off the carrier.

Yes, we're talking CPUicide here. Following the traces from the L3

bridges to their destination solder dots in the array on top of the

carrier, beneath where the core sits and the dots leading inside it

touch, I discovered they were actually connected to the core's

corresponding dots just like all the other traces.

That shoots down my theory about the paths leading to the multiplier

control circuitry having been etched back, cut, or whatever, before the

core was mounted onto the carrier.

So where does that lead us, other than recommending me for committment

to an appropriate institution? Either, as some of you have proposed,

they gave those circuit inputs a lethal shot of current or there may be

some microcode embedded inside the core which can be programmed to

ignore the input logic levels to the multiplier control circuitry. I

seriously doubt the cores themselves are different, though I'm

certainly not going to trash my remaining unlocked Barton to compare

them. I'm already having enough difficulty dealing with my

self-loathing, not to mention the 70 price tag to satisfy my

Athlon XP1800+ Clocked to within an inch... but at a cost to lifespan

2007-10-21 17:24:56
Posted by: Electric eel

My trusty old XP1800 has been running at 2200Mhz now for approx 3 years ( equivalant to maybe an XP2800 / Xp2900.
Bought from an advertised batch of known good overclockers, it cost originally 45 when a XP3000 would have cost me more than 3 times as much!
Did a Cut-and-Shut job on the laserlocks as my mobo wouldn't give me too many options on overclocking.
just lately it has been starting to run hotter than normal...even with a heatsink compound refresh, and the computer has had quite a few unexplained random resets.
I guess that it is finally starting to give up the ghost...but big-up to AMD for it lasting so long.
I intend to replace it...... but with a similar processor (have to be cut and shut again).
3+ years of extra speed was well worth it.
AMD Rocks!... They just need to tackle the Intel core duo now... gain the lead again, and give me a new overclocking goal!

What is the difference between the Athlon XP and the Athlon MP? Say Athlon XP 2000+ and Athlon MP 2000+. The guts of the chip seem to be similar. Are they interchangeable for most desktop motherboards?

Response: Athlon XP won't work in dual-processor systems. In single-processor systems Athlon MP can be used instead of Athlon XP.

can it?

i have a athlon xp 2600+, is there any point in me upgrading to a 3200, will the performance increase be worth it.

thanks brett

Response: It will run up to 20% faster in some applications, but on average you'll see about 10% performance boost

FSB Question

Posted by: Clint

Wondering if you could shed some light on my problem.
Ive had a Athlon XP 2800 with 333FSB that i believe has gone bad. If I were to get a new chip, would it have to be 333FSB also, or could i get a 400FSB - 3000 for example? Currently i can not get into bios because i cant boot, but would there be a setting to allow this?



Response: Find out what processors are supported by your motherboard. You can get a CPU with 400 MHz FSB if your motherboard supports it.

Mobil Vs. Desktop XP CPU's

2008-01-01 06:17:00
Posted by: Jepieriii

Most desktop boards will run either XP or XP-M CPU's however since mobil XP CPU's use power switching to help conserve battery life which means they lower their operating frenquence during idle time or slow working times so instead of for example a mobil XP 2800 normaly runs at 2.08 during slow periods will step down to maybe 1.50 to save power and then switches back to full power when needed. When this same CPU is used in a desktop the desktop board does not reconize this feature and more often than not locks onto the lower operating frenquency thus not letting the CPU to operate with it's full potential so always know your board and what it will do for your CPU and you won't be wondering "What the heck".

There is a fishy site claiming a Barton 3400+

And a special-made Sempron 3300+

The Sempron 3300+ is no different than an Athlon XP 3200+.

I currently have a KT600 mobo with an athlon 1800 xp cpu. Can I expect a large jump in performance if I replace the 1800 xp with a 3200 xp?

Electric EEl, when you did the lazer cut and shut, unlocked the multiplier and FSB, you should increase the voltage by at least .1 v or .125 v's and lower your FSB by about 15% or so.... this will aid in your record heatwave and longevity.

Found this on ebay,AthlonXP 2800+ (AXDA2800DKV3C). They state it's 512/333 but your id. page says 256/266? I would like to believe you as it is what I am looking for. It is not in your list so can you shed any more light on this please?
BTW. Fantastic job you're doing, keep up the good work.

Got on to the vendor, seems he got the number completely wrong,it's actualy a AXDA2800DKV4E, a very fast chip by all accounts, but no good to me. On my search for a fast 512/266, I found this; AXMA3000FKT4C, do you have any gen on it?

Chip remarking or fakes

Posted by: anonymous

On Ebay just at the moment there are alot of Athlon XP processor. Little back from buyers on whether their cpu's are working as yet. For instance there are many 2500 with an "E" at the end of the code making them a 400FSB and there was a 3200 supposed to have a 266FSB. I have notice that steppings on some of these cpu's for sale do not exist in your database for the rated CPU. Manufacture dates seem wrong for particular known steppings. I have heard of remarked chips but dont know of the circumstance this can happen? How would you explain the discrepancies to the information I have found at this site.

I remember shopping on newegg and pricing it out but it was more then I wanted to spend. I could accomplish the same with a Barton core 2500+ Mobile 266FSB some were 333FSB. 170 dollars difference. With my ABIT nf7-s version 2.0 (not to be confused with the nf7s2 board) board I was able to run it at 3500+ at a 400 FSB no probs because all bartons have the same core. In production even today they take a handful of samples from every batch of processors they produce. and test them. The results and ratings of the samples reflect the batch.

This is a very good webpage! It helps me a lot!

I found an Athlon XP 3200+ Thoroughbred CPU which is not listed here. FSB should be 266 MHz, L2-Cache 256 kB and voltage 1,6. But what ist the frequency? 2333 MHz? 133 x 17,5 ?

Response: Athlon XP 3200+ with 266 MHz FSB is most likely a fake processor.
