So when will manufacturers start refreshing their laptops with these? Or, well, have they even been released yet?
Some are including these new processors in the upcoming Windows 8 laptops, which are due in about 12 days. For example, Dell has updated the XPS 15 to the new core i7 if you preorder the Windows 8 version
They have already been released, Sony VAIO's S series has the i7-3632QM and Lenovo's Y series has the i7-3630QM.
Lenovo has shipped i7-3632QM replacing 3612QM.
