wave of laptop refreshes. The F Series gets to play with NVIDIA's new 425M mobile GPU, but the real hotness is to be found in the Z Series, which get access to 2.8GHz Core i7-640M and 2.66GHz Core i5-580M CPU options from Intel. You'll recognize both as mostly roadmap fodder until now, and they're joined by the i5-560M, which makes its debut on a couple of Sony's midrange consumer lines. Basically, it's a whole lot of new silicon in what look like the same old enclosures, but that's not going to stop us from speccing out a Quad SSD-equipped VAIO Z just for the fun of it. We can probably expect these upgrades to journey westward soon as well, so why not hit the source link for a little bit of advance reconnaissance?
