A report from Hungarian site HWSW (cited by Bit-Tech) has a close-up photo of the new AMD AM4 processor socket, and it looks like this will have 1331 pins (go ahead and count them, if you dare!).

AMD's newest socket will merge the APU and FX series CPUs into this new AM4 socket, unlike the previous generation which split the two between AM3+ and FM2+. This is great news for system builders, who now have the option of starting with an inexpensive CPU/APU, and upgrading to a more powerful FX processor later on – with the same motherboard.

The new socket will apparently require a new cooler design, which is contrary to early reports (yes, we got it wrong, too) that the AM4 socket would be compatible with existing AM3 cooler mounts (manufacturers could of course offer hardware kits for existing cooler designs). In any case, AMD's new socket takes more of the delicate copper pins you love to try not to bend!
