AMD Athlon 64 X2 5400+ BE (65 W TDP)

Increse your performance by up to 80 % with the AMD Athlon Dual-Core processor. Work or play with multiple programs without any stalling or waiting. Dual-Core technology is like having two processors, and two working together is better and faster than one working alone.

While the low-power parts are named Athlon X2, the regular models are still sold as Athlon 64 X2. We wanted to also include a regular 65 W AMD processor to look at the power consumption difference, so we decided to get the one that makes the most sense: the 5400+ Black Edition at 2.8 GHz stock speed. There would be an Athlon 64 X2 5600+ at 2.9 GHz, which is also still rated at 65 W TDP—all faster models are 89 W parts—but the memory clock of this part would not be able to hit the full 400 MHz for DDR2-800 operation.
