AMD Athlon 64 for Notebooks microprocessor family

Athlon 64 TF-20 is a low-power single-core microprocessor with 1.6 GHz core clock frequency and 512 KB level 2 cache. Besides 64-bit instructions set and an NX feature (no-execute bit), it also supports Virtualization technology. This, perhaps, is the main reason why this CPU is branded "Athlon 64". Without Virtualization, performance and features of the TF-20 would be no different from Mobile Sempron processors. The processor is packaged into 638-pin package that fits any socket S1 motherboard, but is electrically compatible only with the first revision of this socket - S1g1. The processor was shipped in low-power notebooks, such as Acer Aspire 5516, eMachines E625, and others.
