AMD Athlon SFF 1000 socket: Socket 462

What the Athlon SFF 1000 is

The AMD Athlon SFF 1000 is a 1000 MHz single-core small form factor desktop processor from 2001. It runs one K7 Palomino core at 1000 MHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 180 nm process. Power is rated at 35 W in a Socket 462 package with a 200 MT/s front side bus and a 10x multiplier at reduced voltage.

SFF bins Palomino silicon for compact cases with limited airflow, which separates the SFF 1000 at 35 W from standard Athlon 1000 parts at higher power with the same 1000 MHz rating. AMD aimed the bin at small desktops with small power supplies. The chip supports MMX, SSE and Enhanced 3DNow.

Low clocks with low voltage suit silent office boxes. The 35 W envelope allows a small heatsink with slow fans. That is why SFF parts shipped in compact towers with integrated graphics.

Socket and motherboard compatibility

The Athlon SFF 1000 fits Socket 462 small form factor desktops with Palomino SFF support. It needs a compact board. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Compact towers are the natural match. Boards listing SFF 1000 accept the chip with a 35 W cooler.

Memory, PCIe and cooling

Memory is DDR or SDRAM through the board chipset. The board sets speed and capacity.

A 200 MT/s bus ties the CPU to the chipset, while graphics hangs off the chipset. No PCIe lanes originate on the die. Cooling uses the socket lug clip with a 35 W heatsink.

Upgrade paths

On Socket 462 SFF steps include the SFF 1200 at 1200 MHz where listed. Standard Athlon 1000 parts offer the same clocks with higher power. Beyond Socket 462 a move to Socket 754 needs a new board. The chip lifts with the lever, so swaps need no solder work.
