AMD Athlon XP-M 2600+ socket: Socket 462

What the Athlon XP-M 2600+ is

The AMD Athlon XP-M 2600+ 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 notebooks with DDR slots. This page omits a TDP rating because the cpu_list 45 W figure lacks support in opened sources for this exact bin.

Unsuffixed XP-M numbers cover mainstream mobile bins without a wattage suffix, distinct from 72W bins at the same clocks. All use a 266 MT/s front side bus with PowerNow control. AMD aimed unsuffixed bins at mainstream notebooks where the maker sets power tables per chassis. The chip supports MMX, Extended MMX, SSE, 3DNow and Enhanced 3DNow.

Suffix discipline matters. The unsuffixed 2600+ needs the exact unsuffixed listing in the maker table, since 72W tables use different cooling. Ordering by clocks alone risks a mismatch despite matching frequency.

Socket and motherboard compatibility

The XP-M 2600+ fits Socket 462 notebooks with DDR memory and unsuffixed bin support. It needs a notebook Socket 462 board. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mainstream DDR notebooks are the natural match. Maker tables decide fit by exact suffix.

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 notebook heat pipe for the exact mainstream chassis.

Upgrade paths

On Socket 462 suffixed bins at the same clocks suit large bodies where listed. Higher XP-M 2800+ 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.
