|Acer added another configuration with more powerful single-core AMD Neo microprocessor for its Aspire One 721 netbook. While the original version of the netbook was shipped with Neo K125 CPU, operating at 1.7 GHz, newer netbook uses Neo K145 which runs at 1.8 GHz. Like the older K125, the Athlon II K145 has 1 MB of L2 cache, uses not more than 12 Watt of power, and has the same set of features. Granted, the performance increase with the new CPU is negligible, but it's encouraging to see faster and faster versions of low-power CPUs, as in the long run these small speed increases can add up to a quite big jump in performance.
The Aspire One 721, or AO-721, comes with 11.6" LED display, powered by integrated ATI Radeon HD4225 graphics. The netbook uses AMD M880G chipset, and supports up to 4 GB of DDR3 memory. The listed configuration includes only 2 GB of DDR3-1066 memory, and also features 320 GB hard disk drive, 1.3 MP web camera, and support for 802.11b/g/Draft-N Wi-Fi and Buetooth interfaces.
On Acer website the described configuration has the part number "LU.SB002.375". Searching for this part number brings up a few pages with links to stores, located mainly in Czech Republic and Slovakia, that have this model for sale. The prices for the Aspire One 721 with the AMD K145 CPU start from approximately $430 without taxes. Another Acer 721 model with the K145 processor is LU.SB002.354. This model is currently advertised by a small number of German online shopping sites, and it's main difference from the LU.SB002.375 model seems to be larger, 500 GB vs 320 GB, hard drive.
Acer Aspire One 721 is not going to be the only notebook with the Athlon II Neo K145 microprocessor. Dell Inspiron M101z and Lenovo ThinkPad Edge notebooks, both shipped with AMD K125 and K325 processors, will eventually be upgraded to Athlon II Neo K145.
