Bits and pieces: A4-3450 APU spotted, AMD retires Phenom II CPUs
Jul 12, 2012: The first generation of AMD Accelerated Processing Units, based on Llano core, hasn't been refreshed since the beginning of this year. Considering that AMD plans to replace Llano products with "Trinity"-based ones, and that some "Trinity" parts has already been launched, we didn't expect to see new Llano processors. However, recently updated CPU support information for Biostar motherboards revealed new A4-3450 APU.

AMD cuts prices of Phenom II and FX CPUs
Feb 28, 2012: As you may know, AMD yesterday launched two FX microprocessors, including company's first production CPU, operating faster than 4 GHz. New product releases are usually accompanied by price drops of older models, and it wasn't an exception this time. AMD cut prices on two FX-Series models, and reduced prices for most of Phenom IIs. They also added pricing for A-Series A6-3620 and A8-3820 Accelerated Processing units (APUs).

AMD cuts prices on older desktop models
Dec 07, 2010: With the launch of three new desktop processors today, AMD also dropped prices on many older models. Majority of price cuts were insignificant, typically in the range from 3% to 10%. The price of one microprocessor, Phenom II X4 970, was increased by $5, or by about 3%.

Intel Core i3-550 benchmarks
May 24, 2010: Core i3-550 microprocessor was planned for the second quarter of this year. Although this model is not officially released yet, it is already available in many stores. We tested one of the processors, and compared results to other Intel Core i3 and Core i5 CPUs, as well as a few selected Athlon II and Phenom II dual-, triple- and quad-core microprocessors.

Athlon II X2 benchmarks
May 03, 2010: A few weeks ago we acquired a lot of Athlon II processors with C3 core revision. Although we posted pictures and individual benchmarks to Athlon II CPU pages, and added the results to our benchmark database more than a week ago, we decided to provide benchmarks in more readable format, i.e. as a review.

Compare AMD 555 BE (rev. C3) benchmark results with all tested CPUs from one of the following families:

This CPU does perform very well and very cool in indle even in load.

-Good CPU with high overclockability
-Decent Price
-Unlocking is a plus

-Very Loud Stock Heatsink Fan
-May not unlock 100% (take that as a bonus)
