The E series of GPUs are the embedded cores they put in the APU chips, it would be possible but highly unlikely. This practular one is what went into the A6 chip, if I remember correctly.
This deal that is refered to in the article has more to do with the Power 7 CPU they have in the Wii U. Since the MULTI IDE, is a complier suite made to help balence loads in Multi-core processors and help identify potential bottle necks in the software. Below is the link to the product in question. And one of the support chips if the Power line from IBM which includes the 7XX processor that the WiiU will have.
