The guys over the Dutch Hardware.info site managed to get a Toshiba's N550D netbook with AMD's Fusion C-50 dual-core APU which run at 1Ghz and put it on the test ; comaring the new chip from AMD with the Intel's Atom N450 and N550 .
The C-50 Fusion which run at only 1Ghz has an AMD Radeon HD 6250 running at 280 MHz and supporting the directx 11 and the TDP is only 8 W !
The benchmark results are quite impressive , keep in mind that we are talking about the AMD's C-50 and not the E-350 which is clocked at 1.6GHz,

Here is a video I want to add with a live benchmarking test , the video show the AMD Fusion C-50 APU compared with the C-60 APU:
