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: Idag tar vi en titt på AMD:s nyaste fyrkärniga konsumentklass-CPU. AMD Athlon II X4 640 är en 3,0 GHz-processor och vi kommer att ta en titt hur bra den fungerar mot AMD Phenom II X4 905 och den äldre AMD Athlon II X4 635. Låt oss ta en närmare titt på den.
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.
