AMD C and E series is marketed under AMD Fusion brand and are based on Bobcat core. They have on-chip integrated Radeon HD 6xxx Series graphics. The C series is clocked in the 1GHz to 1.3GHz range and has TDP of 9W. The E series is clocked at 1.3 to 1.65 GHz range and has TDP of 18W. They consume significantly more power as compared to similarly clocked Atom chips, that's because of out-of-order execution and powerful Radeon graphics that has been integraetd into the chip.

The C-series is used in 11.6 inch screen netbooks. It provides better features than Intel Atom processors like Out-of-order execution, Radeon graphics. But CPU clock of just 1-1.3 GHz might be the reason which drive out buyers to Atom devices.
Benchmarks here show that E-350 performs much better than Atom processors, but due to higher power consumption it is not usually used in netbooks. E-350 is used in full sized laptops where it turns out to have lower power consumption than the competitors which usually have 35 W TDP. 14 inch screen E-350 laptops can run upto 6 to 8 hours on stored energy. E-350 is also used in all-in-one desktop computers with extremely compact designs.
