I've been keeping my eye on these for a few weeks now and yesterday they finally appeared on sale. Two new dual core processors based on the current architecture of CPU. The AMD Athlon II X2 processor is actually a new core altogether featuring no L3 cache at all but offers 2 x 1024kB of L2 Cache over the Phenom II's 2 x 512kB. The Phenom II X2 however is a Deneb quad core with two of them disabled, leaving 512kB cache per core and 6MB of unified L3 cache. With the two CPU's clocked at 3.0GHz and 3.1GHz respectively, they are very good performers.
The best part is price, as the Athlon II X2 250 and Phenom II X2 550 are priced at £67 and £79 respectively, which is $92 and $108. This pitches the Athlon II against the Pentium Dual Core E6300 2.80GHz (not to be mistaken with the 1.86GHz Core 2 Duo part) and the Phenom II X2 against the Core 2 Duo E7400 2.80GHz.

Even though the Athlon II X2 250 is a solid performer, the Phenom II X2 at just $10/£10 more is a much better buy for it's large L3 cache, ease of overclocking and the potential to unlock the other two cores. The following reviews show the $108 Phenom II X2 550 exchanging punches with the $170 / £140 Core 2 Duo E8400 3.00GHz CPU. The Core 2 Duo will only come into it's own once overclocked, due to it's larger headroom.

So it would seem that AMD have done it again, bringing some much needed competition to the table. A Phenom II X2 550 + 790GX combo for £150 sounds very promising and I hope to try these out some time!
