AMD Athlon X2 QL-66

The AMD Athlon X2 QL-66 is a dual core processor for laptops based on a mixture of K8 and K10 architecture. The QL-66 integrates a dual-channel DDR2 memory controller and a single 1800 MHz 16-Bit HyperTransport Link (2000 MHz according to CPU-World). Compared to the faster Turion X2 models, the Athlon X2 features less power saving functions (no deep sleep, only 2 instead of 3 P-states).

The performance of the Athlon X2 QL-66 is similar to a 1.4 - 2.1 GHz Core 2 Duo depending on the benchmark.
