AMD Athlon XP-M 2600+ (72W) socket: Socket 462

What the Athlon XP-M 2600+ (72W) is

The AMD Athlon XP-M 2600+ (72W) is a 2 GHz mobile processor from March 2003. It runs one K7 Barton core at 2 GHz with no turbo, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 130 nm process. The package is Socket 462 for large notebooks with DDR slots. This page omits a TDP rating because no opened source states a 72 W figure for this exact XP-M bin.

The 2600+ mobile shares its 2 GHz clocks and 512 KB cache with unsuffixed 2600+ mobiles at lower power, so suffix decides thermal design. All use a 266 MT/s front side bus with PowerNow control. AMD aimed 72 W bins at the largest notebooks with desktop-like cooling. The chip supports MMX, Extended MMX, SSE, 3DNow and Enhanced 3DNow.

Large chassis requirements dominate here. A 72 W mobile bin needs a desktop-replacement heat pipe with strong fans, not a thin notebook cooler. That is why the suffix stays in the model with its own slug.

Socket and motherboard compatibility

The 2600+ (72W) fits Socket 462 large notebooks with DDR memory and a BIOS that lists the 72W Barton bin. It needs a notebook board with high current delivery. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Largest DDR notebooks are the natural match. Only chassis qualified for 72 W mobile operation sustain the bin. Smaller bodies need lower power suffixes.

Memory, PCIe and cooling

Memory is DDR through the board chipset with notebook slots. The CPU has no controller.

Front side bus operation ties the CPU to the chipset, while graphics hangs off the chipset. No PCIe lanes originate on the die. Cooling is the large notebook heat pipe with strong fans.

Upgrade paths

On Socket 462 the unsuffixed 2600+ at the same clocks suits mainstream bodies where listed. Higher XP-M 2800+ Barton parts offer more clocks. Beyond Socket 462 a move to Socket 754 needs a new notebook. The chip lifts with the lever, so swaps need no solder work.
