What the Phenom X4 9450e is

The AMD Phenom X4 9450e is the fastest energy-efficient Agena quad core, a 2.1 GHz part from October 2008. It runs four K10 cores at 2.1 GHz with no turbo, so 4 cores give 4 threads. Cache is 512 KB of L2 per core under a shared 2 MB L3 on a 65 nm process. Power is rated at 65 W on Socket AM2+.

The 9450e is built on the fixed B3 stepping at 1.075 to 1.125 V, part HD9450ODJ4BGH, with no TLB erratum, and its HyperTransport link runs at 1.8 GHz. Board and catalog dates center on October 2008, with some retail listings slipping to early 2009. It exists because AMD stretched the efficient quad line to near-mainstream clocks late in 2008.

Socket and motherboard compatibility

The 9450e needs a Socket AM2+ board with DDR2 memory and a BIOS that recognizes late-2008 Agena steppings. Most AM2+ boards support it after a BIOS refresh. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2-800 and DDR2-1066 in two channels.

HyperTransport 3.0 at 1.8 GHz links the CPU to the chipset. PCIe slots hang off the chipset.

Cooling is a compact 65 W heatsink on the 48 x 96 mm mount, with Cool'n'Quiet trimming clocks and voltage at idle.

Upgrade paths

On Socket AM2+ the 9450e is the efficient ceiling, so the upgrade is a standard-power quad such as the AMD Phenom X4 9650 at 2.3 GHz, or the AMD Phenom X4 9350e at 2.0 GHz for a cheaper efficient part. The AMD Phenom X3 8450e drops to three cores at the same 65 W.
