We’re still months away from the launch of AMD Ryzen 7000 “Zen 4” processors, but new leaks tell us more not only about Zen 4, but also about its successors: AMD Zen 5 and Zen 6.
While there’s plenty to rave about with the Zen 4, AMD looks set to have even bigger performance leaps in store for us in the future, if Zen 5’s rumored architecture has anything to offer.
This massive series of leaks comes from the YouTube channel Moore’s Law is Dead. Citing anonymous sources, the YouTuber spoke about what to expect in terms of architecture from the upcoming AMD Ryzen chips. This includes both consumer-level chips (AMD Zen 4, Zen 5, and Zen 6) and Zen 4C, which targets data centers.
The upcoming AMD Ryzen 7000 Zen 4 CPUs would keep a similar architecture to Zen 4 and bring an upgrade in terms of cores and clock speeds. Zen 4 can deliver a significant IPC (Instruction Per Clock) boost ranging from 15% to 24%. Single-threaded operations can see a 28% to 37% increase, and the same will be true for multi-threaded performance, although the boost may be even greater.
As mentioned, clock speeds will definitely be higher in the Zen 4 range than in AMD’s current arsenal. Twitter user petykemano recently saw what appears to be a very early benchmark of the AMD Ryzen 7 7800X. The processor reached 5.2 GHz, which is a significant upgrade over its predecessor – the Ryzen 7 5800X can only go up to 4.7 GHz. However, it seems that the Zen 4 CPU keeps the same number of cores as the Ryzen 7 5800X, with eight cores and 16 threads in the benchmark. Note that the listing has since disappeared, so this can all be changed.
Zen 4 would also double the size of the L2 cache while keeping the L3 cache the same as in Zen 3. Another big change for AMD, which is not news at the moment, is the fact that the processors will finally support PCIe 5.0 . , DDR5 and LPDDR5. This will take away the lead that Intel Alder Lake had over AMD all year, as Zen 3 does not support these technologies. On the downside, the rumor mill is buzzing with news that Zen 4 may not have DDR4 support at all.

Finally, the Zen 4 range will cover a wide range of processors. The DIY market will receive a full lineup of Ryzen 7000 Raphael CPUs sometime in the second half of 2022. Laptop users have AMD Ryzen 7000 Dragon Range and Phoenix to look forward to, with both slated for early 2023. There are also AMD EPYC Genoa 7004 processors to launch in Q4 2022 and Threadripper 7000 Storm Peak in first half 2023 .
After Zen 4, AMD will release the 5nm-based Zen 4C, which focuses on data centers. While the AMD Genoa will use Zen 4 cores, the successor AMD Bergamo will switch to Zen 4C, bringing the number of cores to 128 cores (while Genoa will be a maximum of 96). Bergamo also offers up to 256 threads and is 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 talk about, which is the future. AMD Zen 5 is still a while away, but all the sources cited by Moore’s Law is Dead expect it to arrive just 11 to 15 months after Zen 4 launches. While that’s a short time, the CPUs would bring major upgrades, with a performance jump as big as Zen 2.
Zen 5 would come with a complete architectural redesign, resulting in a massive IPC boost, seemingly greater than what the switch from Zen 3 to Zen 4 will bring. On the other hand, the clock speeds won’t change much, but we’ll see changes in the data fabric and a completely reorganized cache design. Rumor has it that AMD’s Zen 5 processors are based on TSMC’s N3 or N4P process node.

The first Zen 5 product line to ship may be the EPYC Turin CPU, expected in the second half of 2023. The consumer-level products won’t be out for a while, 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 a long way from launch, and by the time it’s released it might not even be called “Zen” anymore. The naming seems a bit up in the air, but things in terms of specs are pretty exciting, including higher core counts and clock speeds, a new cache design, new accelerators, and more.
We can expect some measure of truth from the above information – Moore’s Law is Dead has yielded many legitimate leaks in the past. Still, as always, it’s best to take it all with some skepticism. That’s especially true for rumors of products a few years or more away, such as the alleged Zen 5 and Zen 6. Even if the leaks are true now, AMD could make some changes along the way.
