The Athlon XP 1500+ is the slowest standard desktop version of the Athlon XP. It was released on October 9th, 2001 along with the 1600+, 1700+ and 1800+ models. The Athlon XP succeeded the standard Athlon 'Thunderbird'. The Athlon XP 1500+ I have is from the 41th week of 2001; that's 8 to 14th Octob... > Read more

The slowest Athlon XP desktop model (clocked at 1333MHz and rated 1500+). It runs cooler than it's predecessor, the Athlon 'Thunderbird', it can process SSE instructions and has a higher IPC (Instructions per Clockcycle).

However, an Athlon 1400 can perform better in several situations because t... > Read more

The 1900+ was launched in November 2001 and was clearly one of the fastest x86 CPU's at it's time. The 1800+ is clearly ahead on the Pentium 4 2000 (Willamette) and so is the 1900+, too.

Technically it's pretty much like the 1600+ model but a tad faster.

The first desktop CPU's using AMD's 'Quantispeed' architecture. Otherwise said: we are dealing with a 'Palomino' core.

AMD claims the AMD Athlon XP is faster per MHz comparing with the regular AMD Athlon 'Thunderbird'. The AMD Athlon XP at 1400MHz has model number 1600+ and should be as fast as a... > Read more

Released on October 9th, 2001 along with the 1500+, 1600+ and 1700+ models. At that time it was AMD's fastest desktop CPU until the 1900+ was released on November the 5th.

The release of the Athlon XP was big news for the computer enthusiasts: it marked a new era for AMD. It was a decent and fas... > Read more

This 2100+ is the fastest Athlon XP that is based on the Palomino core. The 2200+ with Thoroughbred core, which is made using 130nm technology and thus cooler and cheaper to manufacture, was launched on June 10th of 2002. At the time this 2100+ was build (31th week of 2002) the Thoroughbred just hit... > Read more

The first kind of Thoroughbred processors from AMD. The Thoroughbred is the successor of the Palomino core and uses a 130nm manufacturing process. It's a few weeks newer than this 2100+ Palomino.

The second fastest 133MHz (DDR266) FSB-based CPU for socket 462. The fastest is the 2600+ (on DDR266) but it's quite rare and not the best choice of CPU out there. The 2400+ is doing quite well, though.

AMD uses a rating system for their Athlon XP processors. Back in the old days an Athlon XP 150... > Read more

A less common Athlon XP CPU. By the time people were buying faster models the Athlon XP 'Barton' was mainstream. The 'Barton' features 512KB L2-cache whereas the 'Thoroughbred' has 256KB L2-cache.... > Read more

A lot like this Athlon XP 2500+ but about a year older. I picked up this CPU cheap and because it's a year older it has two differences:

1. Different PCB substrate. The older versions have a smooth surface (with modifiable traces).

2. It has been made... > Read more

My first AMD Athlon XP! I bought it along with an EPoX 8RDA and one 512MB DDR333 RAM module back in May 2003. Back then it wasn't the fastest setup money could buy but I selected the hardware for overclocking. The Athlon XP 1700+ ran at 2GHz+ within the first hour I got it. After a while I got it (w... > Read more

An overclocking genuis! This CPU once booted (highly unstable, though) at 2300MHz with only 1,5V and did 2,7GHz using watercooling. My other Athlon XP 'Thoroughbred' CPU's didn't achieve this so easily. Only my Duron 1800 did 2,7GHz as well but doesn't have an unlocked multiplier.

The Athlon XP 2600+ came in three versions and in my opinion this is the best one.

XP2600+ running at 2083MHz with 166MHz (DDR333) FSB and 256KB L2-cache.
XP2600+ running at 2133MHz with 133MHz (DDR266) FSB and 256KB L2-cache.

Just like the 2500+ but one step faster.

The slower Athlon XP's that were made in the end of 2002 had an unlocked multiplier. This meant that overclockers could overclock/tweak more easily. This Barton CPU doesn't have an unlocked multiplier anymore becau... > Read more

Launched 10th of February, 2003. The Athlon 64 (based on the Hammer core) was delayed so AMD had to rely on the Barton core which made it's way onto the Athlon XP 3000+.

Barton is basically just a Thoroughbred core but has 256KB more L2-cache. The first Barton CPU's launched were the 2800+ and 30... > Read more

The 2500+ was the slowest Barton CPU when the new Barton cores were released. Barton is technically a Thoroughbred B core with 512KB L2-cache in total.

Because of the extra L2-cache AMD gave the Barton CPU's a higher rating. The Athlon XP 2600+ with 256KB L2 and 166MHz (DDR333) FSB runs at 2083MH... > Read more

AMD's fastest production Athlon XP! In May 2003 this CPU was released with a 200MHz (DDR400) FSB and a clockfrequency of 2200MHz. A few months later, in October, AMD also released a 166MHz (DDR333) / 2333MHz model.

Almost two years after the introduction of the 2800+ and the 3000+, AMD decided to ship out a 2900+ model. I never saw these CPU's much which is probably due the fact that the Athlon 64 was out for a few months.... > Read more
