What the Athlon XP 1800+ is
The AMD Athlon XP 1800+ is a 1533 MHz single-core desktop processor from June 2002. It runs one K7 Thoroughbred core at 1533 MHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 130 nm process. Power is rated at 51 W in a Socket 462 package with part numbers AXDA1800DLT3C and AXDA1800DUT3C on a 266 MT/s front side bus with an 11.5x multiplier at 1.50 V or 1.60 V. The cpu_list June 2002 date matches the table June 10, 2002, and the monthly value is used here.
The 1800+ Thoroughbred shares clocks with Barton XP-M 2000+ mobiles at 1533 MHz, yet the desktop bin uses Socket 462 tower power delivery without PowerNow savings. AMD placed it between the 1466 MHz 1700+ and the 1600 MHz 1900+ in the June 2002 Thoroughbred stack. The chip supports MMX, SSE and Enhanced 3DNow.
Small power steps with flat cache mark the early Thoroughbred line. The move from 49.5 W on the 1700+ to 51 W on the 1800+ needs no cooler change. That is why boards qualified for slower Thoroughbred parts normally accept the 1800+ without a thermal review.
Socket and motherboard compatibility
The Athlon XP 1800+ Thoroughbred fits Socket 462 DDR boards with a 266 MT/s bus and Thoroughbred support. It needs Model 8 microcode. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Value DDR towers are the natural match. Boards listing Thoroughbred 1800+ accept the chip with a 51 W cooler.
Memory, PCIe and cooling
Memory is DDR through the board chipset in a single channel, matched to the 266 MT/s bus. The CPU has no controller.
A 266 MT/s bus ties the CPU to the chipset, while AGP and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the socket lug clip with a 51 W heatsink.
Upgrade paths
On Socket 462 the steps are Thoroughbred 1900+ and 2000+ parts. Barton 2500+ parts offer 512 KB as a cache lift. Beyond Socket 462 a move to Socket 754 needs a new board. The 1800+ lifts with the lever, so swaps need no solder work.
Frequently asked questions
