Quote from the review at Anandtech:
“The Sempron processors, as we mentioned in this AnandTech Insider article last month, is AMD’s “ron” placement to the Duron processor. The name is derived from the Latin word, Semper (meaning “always”), and the tech suffix -ron (which apparently means “budget processor”). Sempron should fall at a lower performance point than equivalent rated parts from other AMD processor lines. As this processor spans two platforms, it makes sense to compare the new Sempron to both the Athlon XP line of processors and current Athlon 64 processors. And as Sempron is a budget processor, it makes sense to compare it to Intel’s budget line of processors. “
Quote from the review at The Tech Report:
“Yep, that’s the name: Sempron. AMD has elected to stick with its “fake subatomic particle” naming scheme rather than veer into Intel’s “fake member of the periodic table of elements” naming scheme. Sempron is largely a branding exercise, so the name is important. The Sempron name is intended to evoke phrases like “semper fidelis” and other such tokens of solidity and steadfastness. Roughly translated from a mix of Latin and leet-speak, though, Sempron means “always pornographic,” and I fear the little CPU will never fully escape that connotation of its recently fabricated moniker. “
