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.

AMD Ryzen 7000X3D 'Zen 4' 3D V-Cache CPU Performance

AMD currently markets its Ryzen 7000 CPUs against the 13th Gen Raptor Lake CPUs comfortably although the competition does tend to offer slightly better performance and better value at the moment.

The AMD Ryzen 7 5800X3D brought up to 40% and an average of 15% performance increase across a variety of games over the non-3D parts and if AMD makes optimization to the 3D Stacked cache & makes it run slightly higher than the existing cache, then we can see a similar performance boost. If the performance sees a similar or slightly higher performance boost, that would put the X3D chips a good bit ahead of the Intel 13th Gen lineup. But without benchmarks, we cannot verify any of the performance claims yet so it's better to wait a bit for more information.

AMD Ryzen 7000X3D 'Zen 4' 3D V-Cache CPU Price & Availability

Pricing will be the most important aspect of the AMD Ryzen 7000X3D 'Zen 4' CPUs. The Ryzen 7 5800X3D was priced at the same level as the Ryzen 7 5800X but more than a year later. By that time, the Ryzen 7 5800X was already discounted down to $329-$349 US. So the price difference ended up around $100 US so around a 25-30% price bump.

The upcoming AM5 AMD Ryzen 7000X3D 3D V-Cache CPUs can end up around $50 to $100 US higher than the Non-3D part. We can expect the following price points for the 3D V-Cache parts:

  • Ryzen 9 7950X3D - $799 US (+$100 US)
  • Ryzen 9 7900X3D - $649 US (+$100 US)
  • Ryzen 7 7800X3D - $449 US (+$50 US)
  • Ryzen 5 7600X3D - $349 US (+$50 US)

Now these are preliminary prices and once again, none of the SKUs have been confirmed but this is what we believe that the pricing structure might look like. As for the launch, we have managed to get hold of an internal roadmap that more or less confirms that AMD will be unveiling its Zen 4 3D V-Cache parts at CES 2023. The processors will be positioned as the fastest gaming chips on the market and will be taking the gaming performance crown from Intel's Raptor Lake 13th Gen CPUs.
