Are AM4 and AM3+ the Same?

AMD has always had good backward compatibility for its platforms. If you have an older motherboard, are looking to upgrade; and you’re wondering are AM4 and AM3+ the same, the short answer is: No, AM3+ and AM4 are different sockets and are not compatible with each other.

Below, we’ll go through the differences between the two sockets, and whether or not AM3+ is still worth using.

Differences Between AM3+ and AM4

The main differences between AM3+ and AM4 are the following;

Socket: The physical socket is different, and you cannot put an AM3+ CPU into an AM4 socket, or vice versa. The AM3+ socket has 942 pins/holes, while the AM4 socket has 1331 pins/holes.

Memory Support: AM3+ only supports DDR3, while AM4 exclusively uses DDR4.

Chipsets and Features: AM4 is a much more modern socket, and has newer technologies and features to offer. DDR4, PCI-e 4.0 on later AM4 chipsets, USB 3.2 Gen 2, NVMe, and Thunderbolt are some of the most important.

Age: AM3+ was first released in 2011, AM4 was released in 2017

CPU Performance: AM4 offers much newer, and much faster CPUs than AM3+ ever offered.

Is AM3+ Still Worth Using?

Unless you don’t have the budget for an upgrade, AM3+ and the performance it offers is severely lacking compared to today’s standards.

Even the best CPU available for AM3+ gets beaten by a 3rd gen Core i7 CPU from 2012, and gaming performance is rather lacking as the FX series of CPUs never had strong gaming performance, to begin with.

If you’re buying used, AM3+ isn’t really the best choice unless you’re getting a really good deal. You can get better performance from other platforms, as older Intel CPUs generally offer better performance potential for a similar price.


Having gone over the differences, we can confidently reply “No” to the question of “Are AM4 and AM3+ the same?”.

They are completely different sockets and platforms and offer different levels of performance. One is objectively the best choice on the market today, and the other is a relic best left in the past.

We hope we’ve helped expand on your hardware knowledge, and that this information will be of good use to you either now, or sometime in the future.
