Core i7 (dual core, not quad) 620M (Arrandale) percolating along at 2.66GHz. Other curious points here are the 4.8GHz FSB, which sounds a little screwy to us, and a final GeekBench score of 5260, which makes current MBPs clocked at the same speed look like your grandfather with a walker (those ranges hover around 3700-4000 on average). The laptop in question is also allegedly running a fresh version of Snow Leopard (build 10C3067 of 10.6.2), which certainly makes sense if someone is out there benching a new Apple product, though it's not a number we can verify. Still, if you were using a new Apple product, would you be dumb enough to publicly share this info? Probably not, which of course raises the question that this might just be a hackintosh or some other clever spoof (even if we did see a suggestion of new MBPs on the way recently). In the meantime, you can dream of having your pants burnt off by the above monster, and we'll let you know if this thing starts looking a little more real.
