Ergebnis: Priced around the same as the AMD Phenom II X4 905e and performing better in most tests I can only say that this processor is a juicy piece of hardware. It is true, that 640 will consume more power than the 905e, but if you’re only after performance in office and gaming use I can recommend this processor for you. Being compatible with most AM2, AM2+ and AM3 motherboards this processor is a good upgrade path to those who are having single or dualcore cpu:s.
Exzerpt: AMD har været så venlige at låne os den største Athlon II X4 CPU som man kan få fingere i, nemlig 640 modellen, ligesom den lillebror 635’eren som stort set er identisk med denne, har 640’eren en lidt hurtigere clock hastighed.
Zusammenfassung: The Core i3-530 and the Athlon II 640 proved to have around the same overall performance level, making the decision of which CPU to buy purely a decision of which brand you like the most, if you are an average user.
However, there were some specific scenarios that deserve reconsideration of the above statement. If you run professional applications that can recognize and use more than two CPU cores, the Athlon II X4 640 is a better option.
Ergebnis: The Athlon-II X4-640 performed very well against the lower end Athlon-II X3 and X2 processors that we tested it against. When overclocked to 3.8GHz it even got close and overcame to the performance of the i7 920, mostly in single threaded or low-end environments. As I mentioned during the testing, that is pitting a 3.8GHz quad-core processor against a 2.66GHz quad-core processor, and the slower still generally comes out ahead, but that really is to be expected from a CPU...
Kontra: Not as high performance increase as seen from the X2-260 to the X3-445
Ergebnis: A new model of a CPU series is usually a pretty big deal, but six is phenomenal. Not only is AMD increasing the clock speed on these new models, but they are also keeping the top price points the same. So now you can get the new top-tier Athlon II X4, X3 or X2 for the price of the previous top-tier model. Nice. AMD is also dropping the prices on previously released models. That makes the 2.9GHz Athlon II X4 635 the new sub-$100 quad-core.
Exzerpt: We are officially declaring May 11, 2010 "Athlon II" day. Why you ask? Because AMD is launching a total of six new Athlon II processors today, including a new flagship model, targeted squarely at budget conscious consumers. We should point out, however, that all six of the processors launching today feature existing core microarchitectures.
AMD Athlon II X4 640/X2 260 Processors and the MSI 890GXM-G65 Motherboard Review

Exzerpt: Are we tired yet of AMD pushing out slightly faster Athlon IIs and lowering the prices on the entire line? I’m not. Readers of this shouldn’t be either! Last year AMD shook up the budget processor world with the release of their well received Athlon II series of processors. The Athlon II X4 620 was truly a groundbreaking quad core processor, not so much in design, but that it could attain a $99 price point at introduction.
AMD Athlon II X4 640 3.0GHz Quad Core Processor Review
10 Mai 2010
Zusammenfassung: The AMD Athlon II X4 640 may not be the world’s fastest processor, though it isn’t priced like it, either! The low price of $122.00 is aimed at the main stream crowd that likes to see a great price to performance ratio. AMD hit the nail on the head with the Athlon II X4 640 as the price to performance is terrific!
