As I already told, the AMD Athlon 1500MHz 'Thunderbird' does not exist.

The Athlon 1500 CPU you showed in this link is not an AMD Athlon. It's an AMD Athlon XP Mobile Balanced Processor.
The OPN tells what kind of CPU it is. AXMS is the mobile CPU. The Balanced CPU has 256KB L2 cache and only a 100MHz FSB (Normal AMD Athlon XP's use an 133MHz FSB or higher). The vCore is 1,3V so it won't produce much heat  

When looking at the CPU picture it's clearly visible that we're dealing with an AMD Athlon XP 'Thoroughbred' CPU. All AMD Athlon 'Thunderbird' CPU's we're ceramic, not organic like the 'Thoroughbred' CPU's  

Yes, there we're rumours about the AMD Athlon 1500MHz. Did it come or did AMD release the AMD Athlon XP in time ?
All questions, someday, even an AMD Duron XP 1500+ popped up, of course it was fake*, just like the AMD Athlon 1500  
_{*Photoshop- Palomino 'die' on a ceramic packaging with 'Duron' photoshopped on the 'die'}  

When 'googling' I see only overclocked AMD Athlon's. Some 1500MHz models for benchmarking, just overclocked AMD Athlon 1400's. thisshows an AMD Athlon 1500. It's just an overclocked AMD Athlon. Probably an 1333MHz (FSB to 150) or an overclocked 1400 since much of the 1400's we're multiplier unlocked.

@ Thandor

There is a 1500Mhz Thunderbird I just know for sure, thye have told to be rare, but if people don't believe me, then it is hard for me to explain. Maybe ofsome one else told you would of believed them
here some dith proof that it was planned:

and here LOL

"AMD's Thunderbird Athlon core will be taken to 1.5GHz over the coming months, with a part at that speed and another at 1.4GHz to fill the gap between the top-of-the-line chip and the current 1.3GHz Athlon."

"The arrival of the 1.5GHz Thunderbird Athlon paves the way for 1.53GHz, 1.6GHz and 1.67GHz parts based on the Palomino core...."

So there is proof that there were plans of one 
And I am very sure have seen 3 of them in my life at the Computer store where I regulary help out, we don't lie to our customers so why would I lie here. Maybe it is that you only believe in things that allready are and things that not might but are sure to exsist.

@ Exxe

You are right that is an Athlon4., I mentioned the wrong one.

@ the rest

Anyway the info I used to have is hard to trace now, anyways If I get more I will post it asap, hmm sending AMD an email is also not a bad idea...

hmm mkay, wierd then these 1.5 Ghz Athons I seen were Athlon4 CPU's as is hard for me to memorise ..... they did run at a clear standard speed of 1.5Ghz which is 1500Mhz and If I can remember the Athlon4 was the Thunderbird for laptops though i could of been a 1500Mhz Athlon4 but I can't recall that, which troubles me still.

Any it was a long time ago but I do remember the Athlon Thunderbird 1500Mhz it's still fresh in my mind.

I have 400% that it does I have had seen 3 of these things myself, but you must do what is best of course, I can't control your mind.

If you call proof rumours yeah then everyone would say it would be hard to believe....

I have seen them so that's why I believe my 28 year old mind and enslaving my mind won't work so quit it, if you have some usefull ifno please post otherwise skip this topic.

who is that, is that a worker from AMD, I'm not gonna ask a guy I don't even know, I thought at first posting here would solve it, but that was my mistake.

I think I'm gonna ask Marco A. myself, his friend works @ AMD Dresden himself

@ FalconFly I think it is best to close or even remove this topic. it's getting messy, and sorry for asking about the Tbird 1500 it does exsist, it's hard to be removed from my mind, it is best to keep that personal then.

oke mischien heb ik het tch mis idd

sorry for my dutch yes I maybe mistaken afterall, wtd is worng with me these days. I suppose I hear things that shouldn't be there, must come from my medication I'm tak'n the hallucinations and so on
