It depends on the type of AMD processor. The current AM3 generation has 938 pins.
AMD AM2 socket has 940 pins. However, it is incompatible with Socket 940, which is for server processors.
940 pins
941
The Socket AM3 Connector is compatible with the AM3 and AM3+ processors, but not AM2 or AM2+ processors, which have 940 pins instead of the 941 pins of the AM3/AM3+.
Depends on what socket you get. Each may be different. E.G: LGA 771 LGA 775 LGA 1366 Socket 478 Socket 939 Socket AM2 Socket AM2+ Socket AM3
Socket AM3
No, it will definitely not fit. If you have an AM3+ CPU like for example an FX-8150 or an FX-6100, a Phenom X4 or even an AMD Athlon II X2, you have to use an AM3+ socket, or in the case of the Athlon II X2, or X3, or X4, or the Phenom family of CPU's you can use AM3+'s predecessor: the AM3, as well as the AM3+. However, the 939 is a much older socket which is not compatible with most modern day AMD CPU's.

The Intel socket B has 1366 pins. It is also called LGA1366
You can use an amd sempron or an amd athlon II with an am3 socket, but when am3 was released it was meant to be used with the amd phenom line of CPUs. You can use all three: amd sempron, amd athlon II & amd phenom.
