AMD Zen 6 EPYC Server CPU Leak Suggests 50% Higher Core Count

By / Tech / May 21, 2025

The AMD Zen 6 architecture leak suggests some decent improvement in terms of core count. Also, a second Zen 6 core variant, Zen 6c, leaked.

It’s no secret that AMD is working on next-gen server-grade EPYC processors codenamed Venice, which will be based on the upcoming Zen 6 architecture. AMD has publicly revealed that the forthcoming EPYC CPUs are on track for launch and will be based on TSMC’s 2nm (N2) process, which alone should provide a much-needed boost in performance and efficiency.

There will be new AMD EPYC CPUs based on the Zen 6 architecture sometime in the second half of 2026. Therefore, there is a lot of buzz around these processors, and people can’t wait to learn more about them. Luckily, you won’t have to wait long to hear some juicy details about not only the new EPYC CPUs but also the Zen 6 architecture, thanks to some great leaks in recent weeks. Read on to learn more.

AMD Venice Server CPUs Set To Get Much Higher Core Count

The AMD Zen 6 architecture is set to bring a major change, which could allow it to pack more cores per CCD. According to Tom from Moore’s Law is Dead, a reputed leaker in the industry, Zen 6 will have as many as 12 cores and 48MB of L3 cache per CCD, which is a significant increase from the previous Zen 5 architecture.

Also, there was another leak on the Zen 6 EPYC server-grade CPU, which was picked up by HXL on Twitter, and it says the same thing. According to this leak, the Zen 6-based EPYC processor will have 12 cores per CCD, which certainly adds more credibility to the claim.

Therefore, if we take this information at face value, the EPYC 9006 series CPU (presumably based on Zen 6) will have up to 96 cores and 192 threads, since it is expected to have 8 CCDs. It’s a 50% increase in core count over its predecessor, the EPYC 9005 series, which only had up to 64 cores and 128 threads.

This Baidu leak also mentioned that there will be a second variant called AMD Zen 6c, like the previous Zen 5c architecture. However, instead of 128 cores, the Zen 6c-based EPYC CPU will have up to 256 cores and 512 threads, which is a massive increase in core count. A processor of this caliber could have a significant impact on the server CPU market.

What Does It Mean for Ryzen Processors?

AMD usually releases new Zen core-based products into the server market first, mainly in the form of EPYC server CPUs. However, they eventually trickle down to the Ryzen lineup, and it shouldn’t be any different this time. AMD’s Zen 6-based Ryzen processors should come to market sometime in 2026.

Like the upcoming EPYC 9006 series CPUs, the new Ryzen processors should also have 12 cores per CCD. Since the Ryzen 9000 series (Zen 5) had up to two CCDs, the Zen 6-based AMD Ryzen CPUs should also have two CCDs, which would lead to about 24 cores and 48 threads for the highest variant. Lower variants in the Ryzen 7 and Ryzen 5 class processors will have lower core counts, but they should still exceed those of their predecessors.

However, that’s just speculation on my part based on the information provided by the server leaks, so take it with a grain of salt. We will post an update once we get more information about the AMD Zen 6 architecture, so keep an eye out.
