AMD Athlon II Neo K125 1.7  GHz processor review

The nominal operating frequency of the AMD Athlon II Neo K125 Core processor is 1.7 GHz and it has only one core. The Athlon ii Neo K125 has a total L2 Cache of 1 MB. Built on the 45 nm technology, the Neo K125 has a low TDP rating of 12 W. The low power TDP rating helps in the design of fan less systems.


The Athlon ii neo K125 processor has Integrated DDR3 memory controller. The communication to the chipset is using the HyperTransport Bus.

Some benchmarking results are available for the Athlon ii K125 neo. The cpubenchmark.net pass mark score, for example gives it a score of 476. This puts it faster that Intel Celeron M 450 clocked at 2.0 GHz with a passmark score of 464. Even intel Pentium 4 3.06 GHz trails it with a score of 471. Obviously, the improved architecture of the Athlon ii Neo, including the integrated memory controller, plays a role here.

The Athlon ii Neo chips are intended to take on the low cost intel Atom chips. AMD has been successful to some extent in this area. The lack of performance on these chips is the biggest hurdle in their adoption, though, they provide very good battery life.

The AMD Athlon II Neo K125 single Core processors are packaged as BGA ( Ball Grid Array Processors) processors, which means that these are can be directly soldered into the PCB. You can not just take these out from an existing PCB or th e motherboad and replace them.

Some of the recent notebooks, that were found to have the AMD Athlon ii Neo K125 processors include Acer Aspire One AO721-3070 11.6-Inch Netbook, Acer Aspire one 521, Acer Aspire 721.

    My new Asus 1215T has this processor and it is a great disappointment. It’s slow and seems easily confused processing data that this little netbook encounters. I would strongly advise against buying a computer with this processor. From now on, I’ll stay with Intel and dual processors.

    Just wanted to mention that the AMD athlon k125 are great for using as a linux system.
