AMD Athlon XP-M 2000+ (35W) socket: Socket 563

What the Athlon XP-M 2000+ (35W) is

The AMD Athlon XP-M 2000+ (35W) is a 1533 MHz mobile processor from June 2003. It runs one K7 Barton core at 1533 MHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 130 nm process. The package is a 563-pin microPGA for notebooks with DDR slots. This page omits a TDP rating because the Socket 563 page names 16 W and 25 W as low-power envelopes, while the cpu_list 35 W figure lacks support in opened sources for a 563-pin bin at these clocks.

The 2000+ (35W) shares its 1533 MHz and 256 KB rating with the 2000+ (25W) at lower power, so chassis cooling separates the bins. Both use a 266 MT/s front side bus with PowerNow control. AMD aimed 35 W bins at larger thin notebooks with bigger heat pipes than 25 W designs. The chip supports MMX, SSE and Enhanced 3DNow.

Suffixes decide fit here. The 25W and 35W bins at identical clocks need different thermal designs, so the suffix is part of the model with separate pages and slugs. A notebook qualified for 25 W operation cannot assume support for the 35 W bin without maker confirmation.

Socket and motherboard compatibility

The 2000+ (35W) fits Socket 563 notebooks with DDR memory and a BIOS that lists the 35W Barton bin. It needs a microPGA board with 563 lands and power delivery for higher current than 25 W designs. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Larger thin notebooks are the natural match. Maker lists decide fit, since 25 W chassis may lack the cooling for 35 W operation. Socket 462 mobiles do not seat in the 563-pin socket.

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 mobile chipset, while graphics hangs off the chipset. No PCIe lanes originate on the die. Cooling is the notebook heat pipe for the exact chassis, with fan curves set for the higher bin. Service means cleaning vents and renewing paste.

Upgrade paths

On Socket 563 the 25W sibling at the same clocks suits smaller chassis with lower power. Higher Barton 563-pin parts where listed offer more clocks. Standard power Socket 462 mobiles offer higher performance with larger power. Beyond these K7 mobiles a move to Socket S1 needs a new notebook. The chip lifts with the socket mechanism, so swaps need no solder work.
