[Hardware] AMD Ryzen 7000X3D ‘Zen 4’ 3DV-Cache Desktop CPUs Specs, Performance, Price, & Availability – Everything We Know So Far

[BirSaNN]

AMD Ryzen 7000 CPUs are the first to feature the Zen 4 core architecture and the upcoming Ryzen 7000X3D chips will be the first to feature 3D V-Cache coupled with the same Zen 4 architecture. The CPU lineup is expected to be introduced in early 2023 and we are going to talk about what you can expect in terms of specifications, performance, and prices.

AMD Ryzen 7000X3D 'Zen 4' CPUs: Bringing 3D V-Cache Goodness To The Zen 4 Architecture & AM5 Platform
Earlier this year, AMD introduced the Ryzen 7 5800X3D, a CPU that was designed to offer the best value and performance to gamers by leveraging 3D V-Cache technology which allows AMD to stack large pools of cache on top of Zen chiplets, driving up performance in bandwidth starved games & applications. The benefit was clear right from the beginning with reviews showing a huge gaming performance boost that matched and even exceeded Intel's fastest CPU, the Core i9-12900K, at the time. With the Ryzen 7000X3D parts, AMD plans to repeat that and give gamers another boost that could potentially make AM5 the fastest platform to game on.

AMD Ryzen 7000X3D 'Zen 4' 3D V-Cache Desktop CPUs Expected Features:

Minor optimization on TSMC's 5nm process node
Up to 64 MB of Stacked cache per CCD (96 MB L3 per CCD)
Increase In Gaming Performance (Avg & Mins)
Compatible With AM5 Platforms

There are certain rumors and some official information from AMD that we know about the Ryzen 7000X3D CPUs already.

AMD Ryzen 7000X3D 'Zen 4' 3D V-Cache CPU Specifications
The first 3D V-Cache CPU from AMD came in just one flavor, the Ryzen 7 5800X3D. With the Ryzen 7000X3D, AMD is rumored to offer more than just one SKU. Current rumors have pointed to an 8-core and 6-core variant but there's a room open for 16-core and 12-core variants too. We cannot say for sure how many variants will be coming to the market but in the case that we see a full-on 3D V-Cache lineup with four SKUs featuring 16, 12, 8, and 6 core SKUs, then the lineup would look something like the below:

Ryzen 9 7950X3D 16-Core (2-CCD)
Ryzen 9 7900X3D 12-Core (2-CCD)
Ryzen 7 7800X3D 8-Core (1-CCD)
Ryzen 5 7600X3D 6-Core (1-CCD)
The other thing to talk about is the amount of 3D V-Cache we would get to see on each variant. The first 3D V-Cache chip featured 64 MB of stacked cache on a single CCD. If AMD is to keep the exact same cache count, we would get up to 96 MB of L3 cache on the single CCD & 192 MB of L3 cache on the dual CCD SKUs. AMD can go out and offer increased stacked cache amounts on their newer chips but that's something we cannot confirm at the moment.

Another important thing to talk about is the overclocking support. The first generation of 3D V-Cache CPUs didn't get any tuning options and the voltage options were locked (only to be opened up by certain motherboard vendors using BETA/Non-Public BIOS). However, AMD's Robert Hallock (Ex-Head of Technical Marketing) confirmed that while overclocking was disabled for the first chip, AMD could have future generations of 3D V-Cache CPUs that may support overclocking just like any other CPU.

Frequency is important, frequency is important but every processor, every game is always a series of tradeoffs, bottleneck mitigations and in our architecture, when you are in the range of four and a half to five GIgahertz, four or five is enough when you put a ton of memory on top you know you are not limited by frequency anymore, you are not giving anything up to target that frequency, its the performance limiters or the performance accelerators move up, move elsewhere in the architecture so we can dial back on the frequency a bit ease up on the thermals, make it easier to cool and drop in a big extra blob of cache on top which is more transistor density, more thermal density so that's a trade-off that was very easy.

Another tradeoff besides overclocking was the slightly reduced clock speeds and that may still be a thing on the AMD Ryzen 7000X3D CPUs given that the performance benefit that comes from cache makes up for the losses that occur due to the reduced clocks.
