What the Sempron LE-1250 is
The AMD Sempron LE-1250 is a 2.2 GHz budget single core from October 2007. It runs one K8 core at 2.2 GHz with no turbo, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 65 nm process. Power is rated at 45 W on Socket AM2.
The LE-1250 is built on the Sparta G2 stepping with a 1000 MHz HyperTransport link. It exists because AMD stretched the 65 nm Sempron single-core line past the LE-1200 for the cheapest AM2 office towers.
Socket and motherboard compatibility
The LE-1250 drops into Socket AM2 boards with DDR2 memory and needs no special chipset or BIOS beyond standard Sparta support. It pairs with 700 series DDR2 boards contemporary with AM2 parts. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2-667 and DDR2-800 in two channels.
HyperTransport at 1000 MHz links the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is any 45 W rated heatsink on the 48 x 96 mm mount, with Cool'n'Quiet trimming clocks and voltage at idle.
Upgrade paths
On Socket AM2 the upgrade is the AMD Sempron LE-1300 at 2.3 GHz for the fastest Sparta single core, or the AMD Sempron LE-1200 at 2.1 GHz for a cheaper part. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
