2.AM2+: Socket AM2+ is the next generation successor of AM2. The interface is also 940 pins, which was listed in the third quarter of 2007.
In fact, AMD has no plans to launch AM2+ interface, but the release of AM3 interface supporting AMD quad-core K8L series processors was postponed to the second quarter of 2008, during which AMD had to find a transition interface, so AM2+ came into being. Athlon 64x2 Dragon Series.
3.AM3: 938 pins. The biggest difference with AM2+ processor is that AM3 processor will have built-in DDR2 and DDR3 memory controllers and support Hyper-Transport 3.0 transmission protocol. The cache structure of Socket AM3 processor is basically the same as that of AM2+ processor, but the capacity may be further increased.
AMD45 45nm CPU will adopt SocketAM3 interface, which is backward compatible; In other words, the latest AM3 interface processor is compatible with the previous AM2/AM2+ motherboard, but the AM3 interface motherboard is no longer compatible with the previous processor. Athlon IIx2 Snapdragon II, etc.
Extended data
Because the stitches of AM2 and AM2+ are of the same type and can be seamlessly transitioned, AM2+ and AM2 are completely compatible. Manufacturers use this vague concept of compatibility to fool consumers. "Compatibility" does not mean "support". Compatibility can only be used, but there may be performance loss; Only with "support" can it run perfectly on its platform.
The difference between AM2, AM2+ and AM3:
The difference between 1 and Ht bus: the super-transmission of AM2 is only the standard of 1.0/2.0, the working frequency of HT 1.0 is 1GHz, and the maximum data transmission bandwidth is 2GT/s, that is, the super-transmission of 8Gb/s ... am2+/am3. ..
2.AM2+ does not support DDR3, and it is only a transitional interface.
3. The 3.AM3 processor will have built-in DDR2 and DDR3 memory controllers and backward compatible AM2/AM2+ motherboards.
