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...

All that said, I can’t say anything negative about the 640 or 610e in and of themselves. They performed well in benchmark testing and are delightfully inexpensive for quad-core...

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...

Just a notch above the Athlon II X4 630 in AMD's range, the Athlon II X4 640 has a slightly higher clock speed of 3.0 GHz instead of 2.8 GHz. Those extra 200 Hz allow it to overtake the Intel Core 2 Duo E8600, leaving it just behind the Core i3 540. ...

This month we address the disappearing Phenom II X4 965 and Athlon II X4 640, and suggest the eventual phase-out of AMD's entire FX family. The good news is that we now have performance data on the multiplier-unlocked Athlon II X4 750K, which does well. ...

Benchmarking 86 CPUs takes a while. After long last, though, we have 51 models from AMD and 35 from Intel tested in our current suite. If you want to know how your processor sizes up to its competition, you'll find plenty of comparison data inside! 86...

The AMD Athlon II X4 640 ($99.99 list) is a 3.0GHz, quad-core processor with support for 64-bit computing and virtualization, and includes both a heatsink and fan among other features. The chip also sports an integrated DDR memory controller, a 2MB...

Dealing with current news means that we rarely have the opportunity to review old products and of course a comparison between the most recent products and those that came out several years ago can get a little problematic. But we’ve decided to push...

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...

Groundbreaking? No. Unprecedented? Not even close. A nice increase in performance all the while pushing prices down? Definitely. Things can get a bit crowded on a m-ATX motherboard with full size video cards. AMD is milking the Athlon...

As I stated in my opening paragraph, these CPUs for the most part are simply speed bumps in existing product lines along with using the latest C3 revision silicon. These new processors should replace existing models at the same price point, thus...

By Extreme Overclocking on

The results we see from this chip don't differ at all from what we've expected. At stock, it's essentially a slightly clocked up Athlon II X4 635, and when overclocked, it's also the same as an overclocked X4 635. No surprises here. So who would buy...
