Revolutionary AMD Zen 7 3D Core leaks with mandatory cache chiplets for potentially insane gaming performance

We are at the point in the lifecycle of AMD Zen 5 Ryzen 9000 CPUs where leaks and rumors of future AMD CPU architectures are becoming more frequent. We’ve already reported quite a bit about Zen 6 upgrades, including the proposed CPU core counts, clock speeds, and cache sizes. Moreover, leaks have also confirmed that AMD is going to improve the gaming performance of Zen 6 CPUs even more with an increased 3D V-Cache size.

Thanks to Moore’s Law Is Dead, we may now understand AMD’s plans for the CPU architecture following Zen 6. Zen 7, or whatever the Zen 6 successor ends up being called, is reportedly going to bring a lot of new stuff to the table, including a new “3D Core”.

Per the details shared by MLID, AMD is planning one general CPU architecture with Zen 7 that the company will later segment into different products. As such, Team Red is allegedly developing new “Classic”, “Dense”, “Efficiency”, and “Low-Power” cores for Zen 7. AMD is also reportedly splurging on the latest process node for Zen 7. So, whatever the latest node foundries like TSMC/Samsung have ready at the time, AMD is going to use that for Zen 7.

That said, none of the details shared by MLID are as exciting as Zen 7’s new “3D Core”.

MLID hasn’t shared much information regarding the 3D Core, as the leaker is apparently holding back details for a future Zen 7 leak. However, what little we know about Zen 7’s 3D Cores is quite exciting.

For starters, Zen 7’s 3D Core, while employing the same cache stacking concept as 3D V-Cache, is fundamentally different from 3D V-Cache. From what we understand, an individual Zen 7 3D Core will have its own cache chiplet rather than a single cache block underneath the entire CCD. 

AMD’s current-gen 3D V-Cache CPUs, like the Ryzen 7 9800X3D, employ a single 64 MB cache chiplet underneath a CCD that contains 8 cores. So, the 64 MB 3D V-Cache is shared across the CCD. MLID's claim makes it seem like each 3D Core of a Zen 7 CPU will have its own cache chiplet, rather than a single block for the entire CCD.

We’ll have to wait for MLID’s detailed Zen 7 leak to get more context about the 3D core. Till then, this is a pretty exciting development if AMD is actually taking Zen 7 this way because of the potentially insane gaming performance increase.

We already know that 3D V-Cache helps immensely in gaming. For the past two CPU generations, the fastest gaming CPUs on the market have been AMD chips with 3D V-Cache like the Ryzen 9 9950X3D, Ryzen 7 7800X3D, etc. So, it is easy to see how a Zen 7 CPU with 3D Cores with each core having its own cache chiplet could be a gaming beast.

As always, leaks of this nature are highly likely to be false or have missed a few critical details. So, take the information with a giant grain of salt.
