Sempron 140 is the first single-core microprocessor and the first Sempron-branded processor based on the K10 microarchitecture. With 2.7 GHz clock frequency and large 1 MB level 2 cache, this processor leaves far behind all other K8-based Sempron CPUs. The Sempron 140 is even faster than almost all single-core Athlon microprocessors. The only Athlon 64 CPU that matches this Sempron, and only in a some benchmarks, is Athlon 64 LE-1660.
While the Sempron has only one core, it's in fact a dual-core Athlon II processor with one core disabled. The second core may be unlocked on some Sempron 140 microprocessors using "Advanced Clock Calibration" BIOS feature. Sempron with unlocked core is reported by CPU-Z and similar programs as "Athlon II X2 4400e Processor". Not only that, but some Sempron processors overclock really well, and may reach 3.6 - 3.7 GHz. (Disclaimer - overclocking may damage your CPU. Damage, caused by overclocking, is not covered by CPU warranty.)

AMD Sempron 180 mini-review
Sep 17, 2010
: At the end of July we published preliminary specifications of Sempron
180 microprocessors. Recently, we acquired one the these Semprons, ran
a series of benchmarks on it, and compared them with test results of
other budget AMD and Intel CPUs. This mini-review presents partial
benchmarking results and our thoughts of them, and it will be useful
for those who consider buying either pre-built system with this
Sempron CPU, or OEM version of this microprocessor.
