How did AMD benefit from introducing contemporary Stars (K10) microarchitecture into their dual-core CPUs? According to the results of our today’s test session, we tend to believe that the primary reason was to make good use of the triple- and quad-core production scrapping. Objectively speaking, new Athlon X2 7000 series processors will hardly be able to improve AMD’s market standing at this time. The thing is that even though the top Athlon X2 7750 from the Kuma generation turned out faster than the top Brisbane CPU, the advantage is not very significant overall. On average the improvement makes only 3-5%. Moreover, other Athlon X2 7000 series models will not be able to offer any improvement over the already existing Athlon X2 from 5000 and 6000 series.

However, so far it is enough for dual-core AMD processors to retain certain parity in terms of performance with the competitors from Intel – Pentium DC. And although Intel has recently moved them to new 45nm cores, Athlon X2 7750 CPU remains a worthy rival not only to Pentium DC E5200, but also to the newer Pentium DC E5300.

At the same time all other consumer qualities of the new Kuma processors cannot stand any criticism. Athlon X2 7000 series made from Phenom CPUs consume a lot of power and are barely promising from the overclocking standpoint. Therefore, we can only recommend the new CPU from AMD with a number of allowances and comments to take into account.

Nevertheless, Stars (K10) microarchitecture has a lot of improvements compared to K8 microarchitecture, so the new dual-core CPUs working at the same frequencies as the old ones perform much faster than the previous generation CPUs. But, just like with Phenom processors, AMD suffers from the use of old production process. Unfortunately, Athlon X2 7000 have the same problem as the Phenom CPUs: the combination of low frequency potential and high power consumption do not let us see the progress that we could have seen otherwise. Therefore, we are very excited about the upcoming Phenom II X4 CPUs that will use new 45nm core. We really want to hope that the long-awaited transition to finer and more contemporary production process will help AMD overcome its stumbling stone and release highly competitive and promising solutions.
