Differences between Thunderbird, Palomino, Barton ?
It seems possible to purchase Atlon XPs at equal PR ratings yet different types...... What's different about them, say for a processor with a rating of 1800 ? Oh yes.. what does the + sign after the 18OO signify ? What are series 6 or 8 athlons ? Thanks .. liaM |

What is the FSB for a 2500 OPN ?
Or are there various FSBs for it (like for the 2600). Also.. what is the max FSB for a 1800+ unit ??? And, again.. what's different between a Thubderbird, Palomino, Barton ?? thanks liaM I would think that the + means it's a PR rating OPN Code Frequency 1000 1000MHz 1100 1100MHz 1133 1133MHz 1200 1200MHz 1300 1300MHz 1333 1333MHz 1400 1400MHz (desktop) 1400 1200MHz (Mobile) 1500 1333MHz 1600 1400MHz 1700 1467MHz 1800 1533MHz 1900 1600MHz 2000 1667MHz 2100 1733MHz 2200 1800MHz 2400 2000MHz 2500 1833MHz 2600 2083MHz (333FSB) 2600 2133MHz (266FSB) 2700 2167MHz 2800 2083MHz 3000 2167MHz |

What is the FSB for a 2500 OPN ? 166/333MHz Or are there various FSBs for it (like for the 2600). No, the Barton only by default works with 166/333MHz FSB (except the 3200+ which goes with the 200/400MHZ FSB). Also.. what is the max FSB for a 1800+ unit ??? And, again.. what's different between a Thubderbird, Palomino, Barton ?? The Thunderbird was the 2nd K7 core. The fastest one is 1400MHz. They all ran with a 100/200FSB except a few of the last ones which ran with the newer 133/266FSB. The Palomino was the original AthlonXP core. They produced far more heat, had a more primitive production process, and couldn't run as fast as the newer cores. You can't readily buy them anymore. The Thoroughbred was the next AthlonXP core. It ran much cooler, so it could go faster. Most work with 133/266MHz FSB, but some of the faster ones are available for 166/333MHz FSB. The Thoroughbred B uses slightly less electricity & runs cooler. The Barton is basically a Thoroughbred B with additional cache on the chip to make it go faster. As AMD couldn't make the core run reliabily faster than ~2.25GHz, they instead tried to match Intel's top performers by adding cache ram. A Barton XP 2500+ is considered a good chip to overclock - it is the best value for money so long as your motherboard can handle it without fuss. The + sign indicates a PR rating instead of a MHz rating. An Athlon XP 2200+ for example runs as fast as a Thunderbird would if it could run at 2200MHz, athough it is only 1,800MHz. The PR ratings have been a marketing disaster for AMD, as people assume they mean in relation to the Pentium, when infact a XP 2200+ is faster than a 2.2GHz P4. The "for such and such FSB" of each CPU indicates what FSB speed the CPU's clock speed multiplier is set with in mind. You can manually set the CPU's multiplier, and therefore run it at the correct speed with almost any FSB speed, but the process is usually far more involved than you'll ever want to know. |

1500+ - 2400+ = 266fsb
2500+ - 2800+ = 333fsb altho the 2600+ was put out in both 266 and 333 3000+ - 3400+ = both 333 and 400fsb availability. Not too sure about differences in detail. Palomino was an update from the thunderbird/morgan cores, Tbred A was an update from the Palo. Tbred B from A... Barton from Tbred etc. The main diff between the barton and tbreds and below is the cache. tbreds and below have 384k total cache and bartons have 512k total. Durons I think had 256k total (128k L1 and 128k L2, someone correct me if I'm wrong) hope this helps some...

Thanks.. I'm not so lost as I was before your explanation !! But how do you do it, lost as your are ? liaM PS. for sure the 2500 is a great chip, then. I've been running it reliably and cool at 380 FSB and 56=B0C.. |

All this is very interesting.. Before posting here, I went to the = AMD site thinking there'd be a straightforward explanation of the different models. No such luck (except for reading 100+ page PDF manuals..). Check out "lost"'s reply to my post. It's really interesting how AMD shot itself in the foot with PR ratings, increasing cache size on the Barton just to play catch-up..

And, again.. what's different between a Thubderbird, Palomino, Barton ?? thanks liaM The 2600+ doesn't have a varying FSB. From what I understand, there are two versions of it that are sold as XP2600+. An earlier 133/266 FSB version (Palomino), and a later production version which is a 166/333 part (Barton). What's the max FSB for an 1800+ unit? Can't answer that. The standard FSB for it is 133, with the memory going at 266 (as it's DDR). If you plan on overclocking, you're going into unknown territory, as the proc isn't meant to go at that speed, and your personal results may vary from chip to chip. (These are incomplete. If you want full details, go to www.amd.com and read the technical papers). Thunderbird - This was a revision to the original K7 Athlon, which was designed to be equivalent to a Intel P2 or P3. MMX/3DNow instructions. One of the big deal improvements was a core shrink, which allowed lower power consumption, and higher speeds. AthlonXP/Palomino - AthlonXP chips 1800+ to 2500+ are for sure Palominos. Improved cache, better power consumption, and incorporation of the Intel SSE instructions (called 3DNow Enhanced by AMD). They also started using the PR rating at this point. Also, FSB was ramped up to 133, with memory going at 266, as AMD had standardized on DDR memory. AthlonXP/Barton - The newer XP chips. Smaller core, faster speeds, and improved cache. Also, a higher FSB -- 166, with memory going at 333. Don't really know much more about the Bartons. The only real confusion point is the XP2600+, which early in production was a Palomino (the 133MHz FSB version) and the more recent ones are Barton core (166/333). The only way to tell which version you have is to look at the chip (and there, you'd actually have to know what to look for). The retail packaging is identical, so the casual buyer won't be able to tell at a glance. The reason why it's important to know which version is that some motherboards which claim to support the 2600+ only support the Palomino (133/266) version, and might not work with the Barton one. The PR being a performance rating vs how the chip performed compared to an original K7 Athlon (or Pentium 2/3). The + is just marketspeak for "for some stuff, it might perform better than that". Again, I'm certain that I've left out a lot of stuff, as I'm not an expert on AMD CPUs. If you really want to know all the differences, read the white papers on AMD's site - www.amd.com. If you just want more detail, read the articles on hardware sites like tomshardware (www.tomshardware.com) ---------------------------------------- Thanks, MCheu |

Not entirely true... I have the 2600+/266 CPU which is a Thoroughbred
B Core. To my knowledge, there were no palomino cores made above the 2100+.
