AMD has a track record of supporting each successive platform for multiple generations, in stark contrast to the tick-tock cadence kept by its rival Intel. The AM4 platform is still being supported, nearly a decade after its introduction. It has supported five generations of Zen CPUs, and the latest CPU release was in 2025.

That's an impressive history of support, but now the successor is out. The AM5 platform was introduced in 2022, bringing new technologies, a new socket, and a move to LGA design instead of pins on the CPU. That's already three years of support, with three generations of Zen CPUs, with the 7000, 8000, and 9000 series. With that many CPUs released already, the AM5 platform could be halfway through its lifecycle. Will it manage as many years of active support as AM4, or will AMD move onto a new socket platform as new technologies become available?

The story so far for AM5

We've already had three generations of CPUs for the socket

The AM5 socket and the motherboards supporting it were introduced in 2022, with the launch of the Ryzen 7000 series. This was the first time PCIe 5.0 was available on an AMD processor, a move to DDR5 memory, and upgraded power delivery across the board to support up to 230W processors. It also marked a shift from the Pin Grid Array (PGA) socket to a Land Grid Array (LGA) one, like those used by Intel processors, where the pins are on the socket and not the bottom of the CPU.

The Ryzen 8000 series followed that in early 2024, which were desktop APUs with a fairly hefty iGPU. In August 2024, the Ryzen 9000 series launched, which was followed by X3D variants towards the end of the year.

AM5 motherboards have undergone two generations of chipset changes, with X670 and X870 being the flagship chipsets with the most additional PCIe lanes and other connectivity. The midrange motherboards used the B650 and, more recently, the B850 chipsets, and then there were entry-level A620 and B840 chipsets.

If the same cycle of support AM4 enjoyed is replicated for AM5, that would bring two more generations of CPU and one more chipset generation. But it could be even longer. AMD has said it plans to support AM5 through the end of 2027, but that could be extended. Part of that is because, starting on the X870 motherboards, manufacturers added more storage space in the BIOS chip, meaning more processors and features could be enabled over time without shuffling off support for older CPUs.

AM4 was supported for a long time

AMD released new CPUs just this year for the aging socket

AMD hit a home run with Ryzen, and AM4 is still being supported to this day. It was supported for six years before AMD released its successor, AM5, and the changeover period has been long. But it's becoming harder to find motherboards for the CPUs, and DDR4 is no longer cost-effective.

That said, what a run it's had. Nine years and counting, in an industry where two years was the acceptable norm for a socket, with four years being the best effort previously. To enable this, AMD had to get the board partners to support the platform for nearly a decade.

The conventional wisdom was that supporting a platform for that long would hurt sales as consumers kept their old equipment longer. However, the sales figures show that AM4 still sells strongly even with multiple motherboard and CPU generations on the same socket. This includes overlapping AM4 sales even when AM5 was released, so that AMD could serve different market segments. Expect a similar overlap when AM6 arrives, meaning AM5 will get a few more years before its retirement.

But AM3 didn't fare as well

When AMD brought out the AM3 socket in 2009, it brought DDR3 memory to an AMD platform for the first time. Interestingly enough, AM3 CPUs supported both DDR2 and DDR3, so BIOS updates for AM2/AM2+ motherboards enabled the new CPUs to run on the older socket.

It only lasted two years before the AM3+ socket arrived with the Bulldozer architecture in 2011. Bulldozer and later, Piledriver, dropped DDR2 support, so they didn't work in the previous socket, but it wouldn't have worked anyway, as the AM3+ compatible CPUs had an extra pin.

While technically AM3+ was supported for five years until the launch of Ryzen and AM4, the bulk of the CPUs for the platform were released in 2011 or 2012. AM3+ wasn't competitive against Intel's offerings then, and AMD decided not to refresh them while Ryzen was under development, leading to a longer-than-expected lifespan for the ill-fated Bulldozer architecture and the socket it used.

When can we expect AM6?

Assuming AMD keeps the same naming scheme, of course

AMD has said that Zen 6 will keep the AM5 socket, and it's scheduled for 2026 or early 2027. That coincides with AMD's rough promise to support AM5 through 2027, but does that mean AM6 will launch around that time?

Well, that depends. And it depends on two factors, or more accurately, two new specifications. AMD has historically brought a new socket platform out when either DDR memory jumped to the next increment or the PCIe specification did the same.

AM5 brought DDR5 and PCIe 5.0 to the desktop, so we can expect AM6 to want DDR6 memory and PCIe 6.0. DDR6 is nowhere near ready for the desktop, with datacenter use slated for 2027 and home users getting it in 2028 or even 2029 if the lag between DDR5 in the datacenter and home is roughly followed.

PCIe 6.0 is available in the datacenter, with Nvidia's latest Blackwell GPUs. Still, the specification isn't officially certified, so those GPUs haven't technically passed the requisite tests for using the PCIe 6.0 name. And PCIe 6.0 SSDs might be even further out for home users, as Silicon Motion's Chief Executive told Tom's Hardware that he doesn't see the speedy SSD specification hitting home desks until 2030.

AM5 still has plenty of life left in it

Of course, AM6 may launch with DDR6 and PCIe 6.0 support, even if SSDs and GPUs don't initially support the faster connectivity. But either way, we're looking at another two or three years of AM5 support before AM6 is available, and if AM4 is any indicator, another few years after that. While we can't say for certain that AM5 will manage a decade of support, it'll be pretty close to it.
