Advantages: quad-core design handles data efficiently; cheaper than competing Intel quad-core chips.
Disadvantages: Expensive

...for its subpar performance. Unless AMD drops prices more aggressively, it looks like Intel will maintain its grasp on the CPU market for the foreseeable future. For raw performance, AMD's Athlon 64 X2 chips have lingered behind their Intel Core 2 Duo counterparts all year. Only aggressive pricing from AMD kept its old dual-core CPUs in systems and on store shelves. According to our testing, AMD will have to work similar magic with its new quad-core ...
...you can find a prebuilt PC that uses a Phenom 9500 for significantly less than a similar desktop with an Intel Core 2 Quad Q6600, go for it. But unless you can find it for an exceptional price, we advise against the Phenom right now, because its performance simply isn't there. ... Read review

I tested both products and one thing is sure, by adding two extra MB on the processor die, the performance increased quite a little. I've tested both processors in several aplications and the speed difference varies from almost none (rendering), to notable in encoding, compressing, multimedia (3-6 % speed ...
...this at the same price like E6400 processor. The speed is just great for it's price and if you thing it isn't fast enough this processor is highly overclockable. my tested version worked until 3.15 Ghz with the stock cooler included and without increasing the processor voltage. The stability of this core 2 processor is great, never experienced a single type of problem in the long hours of testing .The processor temperature is quite low, even when ... Read review
