AMD Zen 3D: Release Date, Price and Everything We Know

AMD Zen 3D: Release Date, Price and Everything We Know

Last updated:

AMD recently released its flagship AMD Zen 3D processor, the Ryzen 7 5800X3D, and with it came a lot of excitement around the new 3D V-cache technology the CPU is based on.

The Ryzen 7 5800X3D managed to surpass the Ryzen 9 5950X and i9-12900K in real benchmarks, despite having fewer cores and being loaded by a slower base and increasing the clock speed.

Read now: AM5: all we know.

However, the Zen 3D series does not stop at 5800X3D, as there have been reports that AMD may add the Zen 3D collection.

What is Zen 3D?

Zen 3D is a kind of “rehash” with a focus on adding 3D V-cache to the existing Zen 3 architecture. We’ll get to 3D V cache later, but integrating the new caching technology into AMD’s existing architecture is no easy task.


The 3D V cache requires that some devices be put in place first, as the cache is unstable serving cores at higher frequencies. The reason we think this is because AMD dropped overclocking support for the 5800X3D for no reason.

This is not the first time AMD has re-released / re-hashed a CPU architecture. AMD reissued its first Zen architecture under the name Zen + (plus), adding some much-needed performance improvements and clearing out a few bugs that plagued Zen at the time. Maybe that’s AMD’s focus this time too, and fix issues with the 5000 series.

What is 3D V-cache?

We will discuss 3d V-cache as we know it exists in 5800X3D, as AMD may well have done some revisions of the 3d V-cache technology that is integrated into the rest of the Zen 3D architecture.

The 3D cache is not stacked sideways, but vertically, hence the term 3D cache. This drastically increases the number of chiplets you can fit into an area of ​​a given size, resulting in greater cache capacity without sacrificing cache access speeds. The vertical stacking allows AMD to achieve the massive 96MB L3 cache with a total access speed of 2TB / s in its 5800X3D CPUs. The huge capacity is achieved by stacking two layers of 48MB cache on top of each other.

All this has been made possible thanks to AMD’s close relationship with the chip manufacturer TSMC / this relationship allowed them to create a CPU using a new 3D packaging technology.

This allows the CPU cache to be stacked on top of the 5800X3Ds Core Complex Die (CCD) while using a hybrid bonding approach that mixes copper-to-copper bonding with through-silicon vias (TSVs), not just allows the Zen 3 CPU cores and L3 cache to communicate and exchange data seamlessly, but it keeps the CPU profile slim. Allows the CPU to maintain compatibility with the AM4 socket and existing AM4 coolers.

Zen 3D release date

August 2022.

The supposed Zen 3D “rehash” is said to be released at a time before Zen 4 and AM5. That means we can look at a release in August.

Reliable Twitter leaks Greymon55which has proven to be right many times, has indicated that “several” new AMD Zen 3 processors will hit the shelves at some point before zen 4 processors.

We’ll hear more about this new mysterious CPU series next month. So far, we’ve only seen the eight-core, 16-wire Ryzen 7 5800X3D with 3D v-cache technology. Will AMD actually expand Zen 3D and release new CPUs as close to the launch of a new generation? And if so, why?

Why extend the life of AM4 just before the release of AM5?

AM5 like any other new integration will probably have some dental problems, in fact we are sure it will. But there are more than a few reasons why we think AMD has done this.

AMD is probably looking to test its 3D V-cache technology further on a platform it is already optimized and very familiar with. Zen 3 is not only a platform AMD is familiar with, it is a platform AMD knows that users are also familiar with. This means that we will better understand some changes to the platform and the implications of these changes.

We know for sure that AMD will release 3D V-cache integrated Zen 4 chips in early 2023, but after the success of the 5800X3D, it would be foolish not to explore what already works.

Back to the teeth problems, as far as we know, Intel will try to cut AMD with the release of its 13th generation Intel CPUs. Now a new software integration that can have problems, combined with a new rival release, and nothing more to offer than the previous generation, can drive users into the arms of intel.

If AMD extends the life of Zen 3 and AM4 just long enough to get AM5 through the teething phase, they can look for a way to retain users.

If you still need to buy a new AM5 motherboard, you might as well buy an LGA 1700 motherboard and its Intel CPU if AMD turns out to be unstable or full of errors.

We will update this article as more news and information about Zen 3D becomes available.
