Specifications

The triple-core 405e was introduced in October 2009, and for six months it was the fastest low-power Athlon II X3 microprocessor, until it was replaced by 415e model. At this time, middle of June 2010, the 415e is almost impossible to buy in retail, so the 405e still may be considered the fastest low-power triple-core CPU. The 405e runs at 2.3 GHz, and, like all latest AMD triple- and quad-core processors, has 128 KB of level 1 and 512 KB of level 2 cache per core. The CPU employs standard for all Athlon II families features: 64-bit instruction set, SIMD instructions up to SSE3, and Enhanced Virus Protection (the same as Execute Disable bit on Intel microprocessors). Athlon II X3 405e has very low 45 Watt Thermal Design Power, which is more than 50% lower than 95W TDP of standard voltage triple-core Athlon IIs. The processor is manufactured in 938-pin micro-PGA package, that works in socket AM2+ and AM3 motherboards. When used in AM2+ motherboards, the CPU does not support DDR3 memory. Besides AD405EHDK32GI / AD405EHDGIBOX part, which has C2 core stepping, AMD also manufactured 405e model with C3 core revision. That model has OEM part number AD405EHDK32GM.

While the Athlon II X3 405e processor uses three cores, internally it has four physical cores with one core disabled. It is possible to unlock the fourth core on the 405e processors using "Advanced Clock Calibration" option in motherboard's BIOS, but the results could be unpredictable. Good percentage of unlocked triple-core processors would run all operating systems and applications without any problems, some processors would crash randomly when running an application or booting into an operating system, and others may no POST at all. Performance gain from unlocking the forth core can be estimated by comparing the 405e with quad-core 605e microprocessor.

The Athlon I X3 405e runs at the same frequency and has the same Thermal Design Power as the quad-core Athlon II X4 605e CPU. With the exception of the number of cores, all other features on both processors are identical. In applications, that heavily utilize all microprocessor cores, like image rendering, video or audio encoding, the 405e may be up to 25% - 30% slower than the 605e. In all other applications, including many games, performance of the 405e is comparable to model 605e. As of October 2009, the Athlon II X3 405e is priced nearly 40% cheaper than the quad-core 605e, which makes it a much better option for upgrade or new system in cases when low budget is as important as low power consumption and processor performance.

AMD drops prices on full line of desktop CPUs

May 03, 2011: As you may already know, today AMD launched Phenom II X4 980 flagship model, as well as a few desktop processors from Athlon II and Phenom II families. At the same time, AMD dropped prices on existing desktop CPUs. As a matter of fact, every Athlon II and Phenom II desktop model was reduced in price on average by 11.6%.

AMD cuts prices on energy-efficient Athlon II processors

Sep 27, 2010: Earlier this week, on September 21, AMD unveiled 10 new desktop microprocessors. New models included 6 standard-power CPUs, one ultra-low voltage processor, and three energy-efficient "e" models. We just found out that, on top of adding new microprocessors to Athlon II and Phenom II families, AMD also cut prices on energy efficient parts. We also learned prices of recently introduced "e" models.
