Mobile AMD Sempron
This article has focused on desktop versions of the AMD Sempron. However, it's worth noting that the Mobile AMD Sempron, which is based on the Athlon 64, offers support for AMD's Enhanced Virus Protection (enabled by Windows XP Service Pack 2), which protects user-selected applications and files from memory buffer-overrun attacks. Thin and Light Mobile AMD Semprons run at 1.6GHz, drawing 25 watts, while Mobile AMD Semprons for full-size mobile PCs (desktop replacements) run at 1.6 to 1.8GHz, drawing 62 watts.
