But they didn't. HD 7660G isn't enough for playing most games at High settings.
And the HD 4000 will start in $500 range laptops, while the HD 7660G will start in $600 range laptops. At the $500 range you'll have Trinity A8 featuring the HD 7640G, so again, your argument about pricing isn't accurate. And just so you don't go back to the "we don't know pricing yet so I'll assume AMD is cheaper" argument, Trinity and Ivy Bridge have the same 1000-unit pricing as before. The Ivy i3, i5, and i7 will cost OEMs the same amount as the SB versions. For Trinity what AMD did is bump the A8 back a bit: Trinity A10 replaces Llano A8, Trinity A8 replaces Llano A6, and so on. We already know the introduction and follow-up pricing for laptops that were featuring these a year ago, and we can easily apply that here.
