Computer shop windows are full of goods. Each piece of iron, gleaming with glossy sides, as if whispers to the buyer: “Buy me, I’m more modern, more technological, cooler. With me, your computer will just fly”
Eyes run-up, I want both. But how to find exactly “your” device without spending extra money? So which is better: socket Am3 Vs Am3+ Vs Am4.

SUMMARY TABLE: Am3 Vs Am3+ Vs Am4 Motherbord socket
Comparison of sockets of different types and generations is usually done by comparing their older processor models. For AM3 it is AMD Phenom II X6 1100T, for AM3 + – AMD FX-9590 , for AM4 AMD Ryzen 7 2700X.

As you can see from the table, the AM4 has the best performance/energy efficiency ratio. Systems based on processors of this generation are the fastest and most technologically advanced, but they also cost about 2-10 times higher than their predecessors. In addition, they are not very compatible with Windows 7, which many users still use. Adherents of the “7” will not have to abandon it altogether, but in order for it to work on a computer with AM4, you need to tinker.
Processors and boards AM3 and AM3 + can be purchased at a very attractive price, but, as a rule, from hands, since they are no longer brought to stores, and if something remains somewhere, then in a limited assortment. The hardware of this generation has no “misunderstanding” with Windows 7, but modern games and software designed for DDR4 speed and other technologies of recent years will not be able to reveal their potential on it. And you will have to pay more for electricity.
AM3 socket Motherboards
A socket is a processor socket. The brand, generation, and model of processors can be connected to the motherboard depending on its configuration.
Sockets AM3, AM3+, and AM4 are designed for AMD brand CPUs, and the global differences between them are due to the properties of the supported processors and to some extent – the motherboards that are equipped with them.
Socket AM3, otherwise called socket 941 by the number of pins on the board, is intended for the following lines of desktop CPUs of the K10.5 series:
- Phenom II (X2, X3, X4, X6) with 2 to 6 cores.
- Athlon II (X2, X3, X4) with 1 to 4 cores.
- Sempron with 1 to 2 cores.
In 2019, the AM3 interface celebrated its 10th anniversary. It differs from its predecessor, AM2, by its support for dual-channel DDR3 memory and a higher bandwidth of the HyperTransport bus, which is used to exchange data between the processor and the chipset.
Certain Socket AM3 motherboards can work with AM3 + processors (excluding AMD FX) after a BIOS update. Check out detail comparison of LGA 2011 Vs LGA 1151 Sockets.

Upgrading a computer on socket AM3 / AM3 + to AM4 is most often unprofitable since the cost is almost equal to buying or assembling a new system from scratch. Therefore, it makes sense to invest in obsolete hardware only if it will be used for the simplest tasks. For everything else, AM4 is the best choice.
