What the Athlon II X3 450 is

AMD Athlon II X3 450 is a triple core Rana desktop processor that AMD released in September 2010 for budget towers. It runs at a fixed 3.2 GHz with no turbo, so 3 cores give 3 threads. Cache is 3 by 512 KB of L2 with no L3. Power is 95 W on a 45 nm process.

The 450 adds 100 MHz over the 445 at the top of the Rana triple range. Office suites feel quick at 3.2 GHz. It still trails quad parts in threaded work.

There is no integrated graphics on this die. AM3 boards with 7 and 8 series chipsets provide board video where fitted. Memory is DDR3 in two channels.

Socket and motherboard compatibility

The Athlon II X3 450 fits Socket AM3 with 938 pins in µPGA form. All 7 series and 8 series boards boot Rana directly. No BIOS step is needed.

AM3 chips also fit AM3+ boards, while AM3+ Bulldozer chips never fit AM3. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory support is DDR3, two channels. A matched 2 by 2 GB kit suits most 450 towers. ECC is not supported.

HyperTransport links the CPU to the chipset at 2 GHz. PCIe slots hang off the board chipset rather than the processor.

Cooling is the stock 95 W heatsink on the 48 by 96 mm mount. Replacement coolers for this pattern remain easy to find.

Upgrade paths

On Socket AM3 the 450 already tops the Rana triple range, so the next step is an Athlon II X4 for a fourth core on the same board. Memory and storage carry over. A same socket reference at lower clocks is AMD Athlon II X3 445.

A platform move to DDR4 needs a new board and RAM. Keep the 450 tower for home duty.

Frequently asked questions

What socket does the AMD Athlon II X3 450 use?

It uses Socket AM3 in µPGA form.

How is the Athlon II X3 450 different from the 445?

The 450 runs at 3.2 GHz. The 445 runs at 3.1 GHz. Other specs match.

What memory does the Athlon II X3 450 use?

DDR3 in two channels.

Does the Athlon II X3 450 have Hyper-Threading?

No. Three cores give 3 threads at a fixed 3.2 GHz.
