We’re still months away from the launch of the AMD Ryzen 7000 “Zen 4” processors, but new leaks tell us more about not only Zen 4, but also its successors: AMD Zen 5 and Zen 6.
While there’s plenty to be excited about Zen 4, AMD seems to have even bigger performance leaps in store for us in the future, judging by the rumored Zen 5 architecture.
This massive series of leaks comes from Moore’s Law is Dead YouTube channel. Citing unnamed sources, the YouTuber talked about what we can expect in terms of the architecture of the upcoming AMD Ryzen chips. This includes both consumer chips (AMD Zen 4, Zen 5, and Zen 6) as well as Zen 4C, which is aimed at data centers.
The upcoming AMD Ryzen 7000 Zen 4 processors would maintain a similar architecture to Zen 4 and bring an upgrade in terms of cores and clock speeds. Zen 4 can bring a significant increase in instruction per clock (IPC), ranging from 15% to 24%. Single-threaded operations may see a 28% to 37% increase, and so will multi-threaded performance, although the increase may be even greater.
As mentioned, clock speeds will definitely be higher in the Zen 4 lineup than in AMD’s current arsenal. twitter user Petykemano recently spotted what appears to be a very early AMD Ryzen 7 7800X benchmark. The processor hit 5.2GHz, marking a significant upgrade over its predecessor – the Ryzen 7 5800X can only hit 4.7GHz. However, it looks like the Zen 4 processor is keeping the same core count as the Ryzen 7 5800X, appearing with eight cores and 16 threads in the benchmark. Keep in mind that the list has since disappeared, so this is all subject to change.
Zen 4 is also said to double the size of the L2 cache while keeping the same L3 cache as in Zen 3. Another huge change for AMD, which is not new at this point, is the fact that processors will finally support PCIe 5.0, DDR5 and LPDDR5 support. This will remove the advantage that Intel Alder Lake has had over AMD throughout the year, given that Zen 3 does not support these technologies. On the other hand, the rumor mill has been buzzing with the news that Zen 4 might not have DDR4 support.
Finally, the Zen 4 range will cover a wide range of processors. The DIY market will get a full line of Ryzen 7000 Raphael processors in the second half of 2022. Laptop users have AMD Ryzen 7000 Dragon Range and Phoenix to look forward to, both slated for release in early 2023. There’s also AMD EPYC Genoa 7004 processors are expected to launch in Q4 2022 and Threadripper 7000 Storm Peak in H1 2023.
After Zen 4, AMD will release the 5nm-based Zen 4C, which will target data centers. While the AMD Genoa will use Zen 4 cores, the successor AMD Bergamo will upgrade to Zen 4C, bringing the core count to 128 cores (while Genoa will cap out at 96). Bergamo will also offer up to 256 threads, and it will be compatible with the same LGA 6096 socket as its predecessor. We can also expect 12-channel memory support.
We’re done with Zen 4, but there’s more to say, namely the future. AMD Zen 5 is still a long way off, but all sources cited by Moore’s Law is Dead expect it to arrive only 11-15 months after Zen 4’s launch. would bring major upgrades, with a performance jump as big as Zen 2.
Zen 5 is said to come with a complete architectural overhaul, which will lead to a huge increase in IPC, apparently bigger than what the move from Zen 3 to Zen 4 will bring. Clock speeds, on the other hand, won’t change much, but we’ll see changes to the data structure and a completely revamped cache design. AMD’s Zen 5 processors are rumored to be based on TSMC’s N3 or N4P process node.
The first Zen 5 product line to ship could be the EPYC Turin processor, which is expected to arrive in the second half of 2023. Consumer products won’t appear for some time, with Ryzen 8000 Granite Ridge (desktop) expected in late 2024 and Ryzen 8000 Strix Point (laptop APU) in early 2025.
As for AMD Zen 6, we’re still a long way from its launch, and when it’s released, it might not even be called “Zen” anymore. The naming convention seems to be a bit up in the air, but things on the specs front are pretty exciting, including higher core counts and clock speeds, new cache design, new accelerators, and more.
We can expect some degree of truth from the information above – Moore’s Law Is Dead has delivered many legitimate leaks in the past. Even so, as always, it’s best to take everything with some skepticism. This is especially true for rumored products that are still a few years or more away, like the alleged Zen 5 and Zen 6. Even if the leaks are true now, AMD may still make a few changes along the way.
