AMD RDNA 3 is coming soon now that it’s been over a year since AMD introduced its RDNA 2, or Big Navi graphics architecture design, with Radeon RX 6000 series graphics cards. The successor to the 6000 series is almost here , following the typical cadence of AMD products, but times have been anything but typical.
RDNA is the architecture and instruction set for AMD graphics processors. It includes everything from the design of the compute and cache units to the shaders and visual pipeline. AMD RDNA 3 will continue to build on the strong showings the company has made with its recent graphics cards.
While many details about the AMD RDNA 3 have been kept under wraps, there are more than a few leaks to suggest what’s to come for the next generation of graphics cards.
AMD RDNA 3: straight to the point
- What is it? AMD’s next-generation GPU architectures follow the Radeon RX 6000 series.
- When do you leave? Until the end of 2022
- What will it cost? Anywhere from $400 to $2,000+
AMD RDNA 3 release date
There is no confirmed release date for the AMD RDNA 3 graphics cards, but there is good reason to believe that the first models will be released later this year.
During AMD’s Q2 2021 earnings call in late July 2022, AMD CEO Dr. Lisa Su said, “We remain on track to launch next-gen products in 2022, including our Zen 4 processors built with industry-leading 5-nanometer process technology and our RDNA 3 GPUs.” Searching reported Alpha.
However, there might be some reasons to be concerned if AMD is still on that timeline. The company’s subsequent earnings call left out any mention of RDNA 3 GPUs. AMD Keynote at CES 2022 also did not touch the next graphics cards. This could mean that the release schedule is getting shorter or it could be that AMD is planning an upgrade to their current RDNA 2 graphics cards as there are rumorsand talking about RDNA 3 would suck the wind from the sails of these updated cards exactly when AMD needs them to compete with the new Nvidia RTX 3080 Ti.
As three separate graphics cards built on RDNA 3 are expected in the initial lineup, it’s also possible that we’ll only see a portion of them within the year as AMD and Nvidia were slow to release the low-end models after the introduction of flagship GPUs in your new series.
AMD RDNA 3 pricing
We have little basis for guessing AMD’s RDNA 3 graphics card prices. Logically, the new GPUs – Navi 31, 32 and 33 – will be the successors of the Navi 21 found in the price of US$ 999. Radeon RX 6900XT and $649 RX 6800 XT, Navi 22 found at $479 RX 6700 XT and Navi 23 found at $379 RX 6600XTrespectively.
Given the supply chain and logistics issues over the last couple of years that are still causing problems, as well as Possible TSMC price increases for chip manufacturingwe are sure that we will see Radeon RX 7000 Series graphics cards that are more expensive than their predecessors.
With that in mind, RedGamingTech suggested that the high-end model can be configured to be a real beast and can cost upwards of $2,000.
AMD RDNA 3 specs and performance
There’s little more than whispers and rumors when it comes to the specs of RDNA 3-based graphics cards, but those we’ve heard suggest some powerful chips that will borrow a key page from AMD’s Ryzen CPU manual.
One of the first things to understand about RDNA 3 is that it will make another change to how some of the components are understood with earlier architectures. With RDNA 2, the chip contained multiple shading engines, which in turn contained a series of dual compute units loaded with stream processors, texture units, and ray accelerator units.
For RDNA 3, the notion of a computing unit seems to have been replaced with workgroup processors which in turn contain stream processors and other elements, and the new models can simply be stuffed. This could be in part because AMD is adopting a smaller 5nm manufacturing process to fit more into a tighter space, and because it will be using a multi-chip module design – putting multiple GPU chiplets on one chip instead of one chip. monolithic – just like it has done on Ryzen processors. While this is still largely hearsay and speculation, consider the rest even less certain until AMD makes an official announcement.
Putting the new design into perspective, the Navi 31 is believed to have two chiplets, each with 30 workgroups, which contain 256 cores (or stream processors) each. This results in 7,680 cores per chiplet and a total of 15,360 cores for the entire Navi 31 chip – triple the number of stream processors found in the RX 6900 XT.
Common hardware leak @Greymon55 on Twitter suggests the Navi 31 chip plugs into 16GB of GDDR6 memory on a 256-bit bus and includes 256MB (or 512MB, according to sources for RedGamingTech) of the 3D Infinity Cache, greatly increasing performance to compensate for not using GDDR6X and running at up to 2.5 GHz.
The Navi 32, meanwhile, would have 40 workgroup processors, 12GB of GDDR6 on a 192-bit bus, 192MB of 3D Infinity Cache, and would run between 2.6 and 2.8 GHz.
The Navi 33 drops to 16 workgroup processors, 8GB of GDDR6 on a 128-bit bus, 64MB of Infinity Cache, and clocks between 2.8 and 3.0 GHz.
To put this in more perspective, the Navi 31 would have the aforementioned 15,360 stream processors, the Navi 32 would hit 10,240, and the Navi 31 would boast 4,096 (an impressive distance from the number on the Radeon 6900 XT).
While teraflops don’t tell us everything about a GPU’s performance, it can be a useful metric for comparison. And taking the core counts and clock speeds, we expect the Navi 31 to peak at 76.8 TFLOPS of FP32 performance, the Navi 32 to get 57.3 TFLOPS, and the Navi 33 to hit 24.6 TFLOPS.
How does this compare to the latest and greatest cards currently on the market? The Radeon RX 6900 XT has 23.04 TFLOPS of FP32 performance and the RTX 3090 offers 35.7 TFLOPS. In other words, the RDNA 3 chips could be causing serious problems for even the best of Nvidia unless the RTX 4090 is as fast as rumored.
We expect the new chips to deliver a huge increase in efficiency. Switching to a small manufacturing process will play a role in this. And AMD Executive Vice President Rick Bergman, even before the release of RDNA 2, said that RDNA 3 would offer a similar leap in performance per wattwhich should mean they will be 50% more efficient than RDNA 2. That doesn’t mean they still won’t be energy hungry, as RedGamingTech suggests Navi 31 boards should consume around 375W of power, but can go up to 450W.
We’ll have to wait and see how much of this turns out to be true.
