AMD Athlon II X4 640 Processor Review

» Discuss this article (13)


When it comes to the bottom line, the AMD Athlon II X4 640 takes the lead for the Athlon II series processors with its increase in speed. Even with only a 100MHz increase, the Athlon II X4 640 has the edge it needs to sneak in as top dog. Now here is the quirky part. The Athlon II X4 640 is essentially an Athlon II X4 635 with an increase in the multiplier by a half. So is it worth it  to pay a bit more for the X4 640, when you can just overclock the X4 635 by raising the multiplier to 15x? Well this all depends on your usage of the processor. If you are just buying it for a workstation or HTPC, then I would opt for the Athlon II X4 635, which will be dropping to sub $100 pricing with the release of the Athlon II X4 640. 

Now, if you already have the last generation Athlon II X4 635, then I suggest you keep it. It's not worth paying extra for a little performance increase. Now if you are looking for a solid, low cost, quad core for your HTPC or workstation, then you cannot go wrong with the Athlon II X4 640 processor. At that price, you could build a complete system for what one of the more "high end" CPUs go for. However, if you want an easy to achieve, stable overclock as well as excellent performance for the price, then the Athlon II X4 640 at a low $122, is the CPU for you.




  • Very inexpensive quad core
  • A 100MHz increase of previous generation
  • Great bang for your buck



  • Low L2 Cache holds the potential back.
