AMD RDNA 3 Release Date, Price And Specs [May 2022 ]

AMD RDNA 3 Release Date, Price And Specs [May 2022 ]

2020 was an exciting time in both the PC and console world. We saw brand-new CPU and GPU releases from AMD and NVIDIA, but we also got the long-awaited next-gen consoles from Xbox and Sony.

These releases enjoyed significant performance improvements from their predecessors, generally thanks to the transition to a smaller (7nm) fabrication process from TSMC and Samsung.

TSMC already has a 5nm process in the works, and AMD plans to base its RDNA 3 and Zen 4 architecture on that. As a result, further performance improvements are expected.

Let’s see what RDNA 3 GPUs will offer.

Why We Should Be Excited For RDNA 3

AMD was not exactly present in the flagship/high-end sector of the GPU market over the past several years. However, that exclusion from the high-end GPU sector ended with the RDNA architecture and the Radeon RX 5000 and RX 6000 series.

The RX 6900XT easily exchanges blows with the RTX 3090 in raw rasterization performance, and that’s NVIDIA’s fastest consumer GPU. Although lacking in ray tracing, these RDNA 2 GPUs still are a great choice.

The last time AMD provided a counter to NVIDIA was more than ten years ago in 2011, with the HD 7970 against the GTX 580 and GTX 680.

If AMD makes another competitive comeback with RDNA 3 to step up the rivalry, we should see a considerable improvement in price-per-performance from both companies.

These things are why we should be excited for RDNA 3.

Release Date

Official details on specifications and release date should be available middle of 2022.

For a more accurate release date, we’ll have to take a look at recent leaks which suggest that both ZEN4 and RDNA3 will be released simultaneously in Q4 of 2022.

However, recent leakers like greymon55 share rumors that Nvidia and AMD will release their next-gen communication at the same time in September 2022.

We got another confirmation during AMD’s Q4 2021 earnings call that RDNA 3 GPUs are definitely coming in 2022.

Lisa also mentioned that AMD is making a lot of investments to ensure they can satisfy demand with enough supply and finally end the GPU market problems of 2020 and 2021.

We’ve been working on the supply chain really for the last four or five quarters, knowing the growth that we have from a product standpoint and the visibility that we have from customers. So in regards to [the] 2022 supply environment, we’ve made significant investments in wafer capacity, as well as substrate capacity and back-end capacity.

AMD’s gaming GPU architecture roadmap

Before RDNA 3 releases though, a couple of refreshed RDNA 2 GPUs are filling the GPU market void for 2022. These GPUs are the RX 6950XT, RX 6750XT, and RX 6650XT GPUs which were released in May of 2022.

These compete against NVIDIA’s Ti variants like the 3090 Ti.

Of course, the performance difference between the old and new RDNA 2 GPUs is nothing significant. This is just a stop-gap before RX 7000 GPUs release, a step that prevents Nvidia from taking over the entire GPU market mindshare with their Ti variants.

Specifications

A new generation of the RDNA architecture on a 5nm fabrication process (from TSMC) sounds promising. It’s exhilarating once we consider the potential performance and efficiency improvement.

Take the performance per watt increase between AMD’s old GCN architecture and RDNA 1 as an example.

The imposing part of the RDNA architecture was the monumental 50% performance-per-watt leap from RDNA 1 to RDNA 2. As the architecture matures, performance and efficiency improve. Such an example is Intel’s 14nm+++ arch).

AMD claims that another 50% leap is expected in this new generation of AMD GPUs too.

Zen 4 (Phoenix) APUs will have a GPU based on the RDNA 3 architecture which is comparable to the performance of an RTX 3060M according to greymon55.

Just the rumor that AMD’s integrated GPU may perform as well as Nvidia’s mid-range dedicated laptop GPU is crazy enough. If this is true, we can expect much lighter gaming-capable laptops and even smaller form factor PCs.

For more specification-related information, check the Specifications Rumors heading.

Architecture

Multiple sources claim that Navi 3 will have a chiplet design or, more specifically, a multi-chip-module (MCM). This is a type of GPU we have never seen before. The only current such GPU is AMD’s Instinct MI200 SKU for computing.

However, we have seen this same design in AMD’s Ryzen processors. The chiplet design of their processors is their secret formula for the considerable increase in performance and physical cores.

Maybe this secret formula will also work with their RDNA 3 graphics cards.

However, the problem with this kind of chiplet design is the increase in latency.

For Ryzen, the solution was fast RAM which compensated for that latency. Unfortunately, this solution is not viable for GPUs and high latency can cause a severe downgrade in performance.

Still, the benefits of a chiplet design are worth it as it effectively reduces the price of a CPU almost by half.

Both SLI and Crossfire technologies always had issues with latency between multiple GPUs, and we now know that running GPUs in parallel is not optimal.

Because of this, AMD has devised a unique solution: an active bridge that connects all of the chiplets. The first GPU chiplet would also be connected with the CPU directly via the Infinity Fabric.

AMD’s active bridge as a solution to reduce latency

Additionally, greymon55 leaked that Infinity Fabric could be 3D stacked for RDNA3. This will double the Infinity Cache up to 512MB (for Navi 31).

Another exciting addition to RDNA 3 GPUs could be the supposed Accelerator Processor Die or APD. It seems that this new die will be stacked on top of the main GPU chiplet and will take a role in machine learning tasks.

This offloads tons of work for the primary GPU, allowing it to do regular rasterization while the APD can work on things like ray-tracing.

This information comes from a recent patent application publication by AMD.

Here are some images explaining how it all works:

Keep in mind that it is possible that this new technology might not end up on RDNA 3 GPUs.

Specifications Rumors

Rumors claimed that Navi 31, a GPU part of the RDNA 3 lineup, will have two chiplets with 80 CUs. However, AMD dropped the term CUs (Compute Units) entirely.

Instead, AMD’s flagship, and probably all of the RX 7000 GPUs, will use WGP (Work Group Processors). The rumor that Navi 31 will come with two dies on a 5nm node (GCDs or Graphics Core Dies) and one Multi-Cache Die on a 6nm node is most likely true.

We will use this diagram by Olrak29_ to help explain exactly what’s packed into those two GCDs and the single Multi-Cache Die.

Navi 31 dies visualized in a diagram.

Both GCDs will have 3 Shader Engines (SE) and each with 2 Shader Arrays (SA). This adds up to a total of 12 Shader Arrays and 6 Shader Engines in one Navi 31 GPU.

Every WGP has 8 SIMD32s, and every Shader Array has 5 WGPs.

With this diagram, our estimates were that the RX 7900 XT will have 15,360 cores/streaming processors. But, it seems that everyone’s estimates were a bit too zealous.

This rumor from Redfire75369 claims that Navi 31 will actually have 12288 streaming processors which means that the number of WGPs per Shader Array is also lower.

While it is lower, that’s still double the cores compared to the RX 6900 XT (5120 SPs).

In addition to that enormous jump in core count, rumors are circulating that Navi 31 will be rocking 512 MB of Infinity Cache compared to just 128 MB on the RX 6900 XT thanks to their new 3D memory stacking technology

This new piece of information makes a lot of older leaks obsolete. The expectations that Navi will have 3x performance over RDNA 2 seems too ambitious now.

Older rumors based on the 15360 SPs expectation

With these new specifications leaks, Navi 33 ends up with considerably fewer SPs than the RX 6900 XT. But, with Infinity Fabric, 3D stacked cache, higher clock speeds, and ADP, Navi 33 might actually be faster.

Greymon55‘s latest leak also reports that Navi 31 will come with only 16GB of GDDR6 VRAM. We hoped for GDDR6X and maybe more VRAM.

Navi 31 gets 256 MB of 3D stacked Infinite Cache, 192 MB for Navi 32, and 64MB for Navi 33.

Another thing to note is AMD’s response to NVIDIA’s DLSS feature, FidelityFX Super Resolution (FSR), which could provide a bit of extra performance for RDNA 3. Although, FSR does also work for NVIDIA GPUs.

Radeon Super Resolution is an alternative upscaling option for AMD GPU users.

Performance Rumors

We’ve seen frequent rumors about all the possible SKUs from RDNA 3 and its architecture, but we haven’t seen much about potential performance increases over Ampere or RDNA 2.

At least we hadn’t until Tom from Moore’s Law Is Dead shared a few RDNA 3 and RDNA 4 whispers.

As seen in the image above, Tom expects a 90-130% performance increase from Navi 31 over Navi 21. A bit hopeful, especially after we discovered that RDNA 3 will have less SPs than expected.

However, this new MCM/Ryzen-like chiplet design might actually allow for such huge performance improvements.

That’s not all, though.

Energy efficiency should improve, but total power usage is also going to be higher. In the image above, Tom from MLID mentions a power consumption between 375W and 450W.

Navi 32 will supposedly be at least 20% faster than the RX 6900XT. But, Navi 32 SKUs will probably release in early 2023.

Here’s what Tom has to say about these Navi 31 and 32 early leaks in this video:

Our original assumptions were that these Navi 31 cards will stomp Nvidia, but, the new rumors that Ada Lovelace will be using TSMC’s 4nm fabrication process instead of 5nm changed our vision.

Nvidia will definitely be very competitive throughout 2022, but that performance might come at very high power costs. So, AMD could be the GPU efficiency king for 2022.

SKU Rumors And Price Estimates

Another leak/speculation by 3dCenter.org suggests that AMD’s RX 7000 SKUs will be a mix of RDNA 2 and RDNA 3.

Here’s a table to help you understand the new lineup of GPUs.

Radeon RX 6000 seriesRadeon RX 7000 seriesNavi 31 (5nm + 6nm)
RX 7900 – between $1000 and $1500Navi 32 (5nm + 6nm)
RX 7800 – between $600 and $1000Navi 21 – RX 6800/RX 6900$579/$1000➔Navi 33 (6nm)
RX 7700 – estimated at $450Navi 22 – RX 6700$479 ➔ Navi 22 refresh or a 6nm refresh
RX 7600 – estimated at $350Navi 23 – RX 6600$379 ➔ Navi 23 refresh or a 6nm refresh
RX 7500 – estimated at $250 Navi 24 – RX 6500 $200 (alleged) ➔ Navi 24 refresh or a 6nm refresh
RX 7400 – estimated at $150Table explaining the SKUs of the next Radeon GPUs and possible refreshes

As seen in the table above, there will probably only be two or three “true” RDNA 3 cards, while the rest will be a refresh of the SKUs from the last generation.

All current leaks mention that Navi 31 and Navi 32 will use a combination of 5nm compute dies with 6nm I/O and Infinity Cache dies. Navi 33 will use 6nm.

Hopefully, this mix between 5nm and 6nm means better pricing for us.

When it comes to the above-mentioned refresh, we can’t be sure whether it’s just going to be a price drop combined with a frequency boost, or maybe the refresh will get an upgrade to 6nm.

Either way, with the current state of the GPU market, we welcome these kinds of price drops.
