Is AM5 The Wise Option or Is It AM4?
AM4 or AM5? AM4 vs AM5? Which socket should you stick to? Which socket would be the best investment? which socket will perform the best? a lot of questions come to light when we are talking about building a PC with an AMD Ryzen CPU.
Since AMD launched the AM4 socket in 2017, it has gained a strong reputation among PC builders for its affordability and performance per dollar. The AM4 socket supports AMD’s 3000, 4000, and 5000 Ryzen CPU series.
However, with the introduction of the AM5 platform and the new Zen 5 architecture using the LGA 1718 socket, AMD has just unleashed powerful yet affordable CPUs with support for DDR5 and PCIe 5. The AM5 socket will be supported until 2027 with upcoming AMD 7000, 8000, and 9000 CPU generations.
If you are building or upgrading your PC in 2025, you might be unsure whether to go with the budget-friendly AM4 socket or to invest in the new, future-proof AM5 platform which will be upgradable for years to come with new Ryzen CPUs on the way.
In this article, we will break down the differences between the two sockets, AM4 and AM5. We will explain them in detail and dive deep into their chipset differences, we will see how the latest AM4 and AM5 CPUs will perform and also discuss the available upgrade path for both sockets.
Finaly, we will keep budget considerations in mind and tell you the best use case scenarios for each AMD socket and, last but not least, examine CPU compatibility for both platforms.
What Are AM4 and AM5?
AM4 and AM5 are CPU sockets, each one has its own chipsets. The AM4 and AM5 CPUs were developed by AMD and were named AMD Ryzen processors, they connect to the right motherboard with either PGA (Pin Grid Array) or LGA (Land Grid Array).
AM4 socket uses the old PGA technology while the modern AM5 socket uses the modern LGA surface-mount technology used by the latest Intel CPUs.
What is AM4?
AM4 is a PGA (Pin Grid Array) socket, which means that the pins connecting the CPU with the motherboard are on the CPU itself. It was released in 2016 and supports PCIe 4 and DDR4 RAM only. It’s the most popular AMD socket among budget PC builds and it’s still used by a lot of people.
What is AM5?
Unlike AM4, the AM5 socket is an LGA socket, meaning that the pins connecting the CPU with the motherboard are soldered on the motherboard itself. AM5 is AMD’s latest CPU socket with support for PCIe 5 and DDR5 RAM. AM5 was designed for serious businesses, hardcore gamers, and content creators.
What About CPU Compatibility Between AM4 and AM5?
Your motherboard should be compatible with either AM4 or AM5 socket. CPU compatibility is an important factor to consider when choosing one of them for your next PC build.
PGA AM4 socket will not fit in a motherboard that supports the LGA AM5 platform and vice versa. Each AMD platform supports different generations of AMD Ryzen processors.
AM4 Compatible CPUs List
- Ryzen 3000 (Zen 2)
- Ryzen 4000 (Zen 2 – APUs Only – OEM)
- Ryzen 5000 (Zen 3)
Most AM4 motherboards will need a BIOS update to support newer CPUs. Compatibility depends heavily on the motherboard chipset (e.g., B450, X470, B550, X570). We will dive deep into different AMD’s AM4 and AM5 chipsets in the next chapter.
AM5 Compatible CPUs List
- Ryzen 7000 (Zen 4)
- Upcoming Ryzen 8000 series
- Upcoming Ryzen 9000 series (Zen 5 and beyond)
AM5 is based on the LGA 1718 socket design and supports only DDR5 memory. It’s built for the future, with long-term support promised by AMD through at least 2027. Newer CPUs will get released for this platform that will benefit from newer technologies that will be announced in the future.
What About AM4 and AM5 Motherboard and Chipset Differences?
Understanding the difference between AMD’s AM4 and AM5 chipsets is essential to make the best buying decision when you want a specific platform, whether be it an AM4 or AM5.
Note: An AMD motherboard is always named after the chipset it is equipped with. It can also contain some letters to the right side to indicate the form factor of the motherboard.
AM4 Motherboards & Chipsets
AM4 Entry-level Chipsets
AM4 has a wide range of motherboards with different chipsets that target different people and various budgets. AM4 has entry-level chipsets which are A320 and A520, those chipsets are designed for anyone building a new budget PC and don’t require powerful CPUs with overclocking capabilities.
Entry-level chipsets don’t support overclocking and don’t feature strong CPU VRM (less CPU voltage stability) that are required by the most powerful CPUs available for AM4. The latest powerful CPU that was released for AM4 is the AMD Ryzen™ 9 5950X.
It consumes up to 105W and thus it needs a decent motherboard with good VRM to run smoothly. Entry-level chipsets also don’t support high memory bandwidths and it’s suitable for basic home/office use.
Let’s take the A520 chipset, for example. It comes in different motherboard sizes: Mini ATX, Micro ATX (mATX), ATX, and the most expensive one, the extended ATX or EATX.
We talked about various motherboard sizes, specifically the mATX and ATX in our latest blog post.
A320 is very outdated and should only be considered if you’re working with 1st–2nd Gen Ryzen. If you found a good deal and all you need is a PC for home/office use, go for it!
A520 is the recommended entry-level option for modern budget builds as it offers better memory support and memory overclocking capabilities. This chipset is a Ryzen 5000 ready, it might require BIOS updates to run in some cases, but it’s still an improved chipset compared to the A320.
AM4 Mid-Range Chipsets
AM4 has mid-range chipsets: the B450 and the B550, they are designed for anyone interested in building a PC for gaming and productivity purposes.
These chipsets often come with more VRM phases (more stable voltages), more M.2 NVMe SSD ports, and more USB and SATA ports compared to entry-level chipsets. Also, the B450 and B550 support overclocking, especially on the B550 chipset.
These chipsets might be the best choice for you as they balance the price, raw performance, and future-proofing. B450 is a great budget-mid-range option for Ryzen 5 and 7 CPUs, especially if you’re reusing DDR4 memory and don’t need PCIe 4.0.
On the other hand, B550 is a stronger chipset offering PCIe 4.0 and has better overall build quality. It is perfect for Ryzen 5 5600X, Ryzen 7 5800X, and even Ryzen 9 5900X in non-extreme setups with overclocking enabled.
AM4 High-End Chipsets
AM4 has high-end chipsets: the X370, X470, and X570, these chipsets are the perfect choice for enthusiasts seeking the highest performance possible regardless of the cost or budget as they can be considered an investment.
They can be used for gaming, serious productivity projects, and content creation. These chipsets support full CPU and RAM overclocking as they feature more VRM phases that can regulate the voltage perfectly.
AM4 high-end CPUs consume too much power, which means that they require strong VRM with a lot of phases to regulate the drawn power and voltages efficiently.
X370 is outdated just like the A320, they are only worth considering for legacy systems or very simple, more specific use cases.
X470 is a solid high-end platform for the Ryzen 2000 and 5000 series, it offers reliability and modern features without the extra power draw of X570.
X570 is the best AM4 platform, offering full PCIe 4.0 support, and top-tier VRMs with a lot of phases that can regulate voltages for Ryzen 9 AM4 CPUs. The X570 is ideal for Ryzen 9 5900X/5950X users or anyone building a powerful AM4-based workstation or a decent gaming setup.
AM5 Motherboards & Chipsets
