AMD RDNA 3: What yous need to know most AMD's next graphics cards
AMD RDNA 3 will before long exist upon us now that it's been over a year since AMD introduced its RDNA 2, or Big Navi, graphics architecture design with the Radeon RX 6000 series graphics cards. The 6000-series successor is well-nigh due, going by AMD'southward typical product cadence, but times have been anything but typical.
RDNA is the compages and pedagogy fix of AMD'southward graphics processors. Information technology includes everything from the design of the compute units and cache to the shaders and visual pipeline. AMD RDNA three will continue to build upon the strong showings the visitor has made with its recent graphics cards.
Though a lot of details about AMD RDNA 3 has been kept under wraps, there are more than a few leaks to hint at what'due south to come for the adjacent generation of graphics cards.
AMD RDNA 3: cut to the hunt
- What is it? AMD's next-gen GPU architectures post-obit up the Radeon RX 6000 Series.
- When is information technology out? As shortly as the end of 2022
- What will it cost? Anywhere from $400 to $ii,000+
AMD RDNA 3 release engagement
There's no confirmed date for the release of AMD RDNA 3 graphics cards, but there's good reason to believe the showtime few models volition come out at the end of this year.
During AMD's Q2 2021 earnings telephone call at the finish of July, 2022, AMD CEO Dr. Lisa Su, said, "Nosotros remain on rail to launch next generation products in 2022, including our Zen 4 processors built with industry-leading five-nanometer process technology and our RDNA 3 GPUs," Seeking Blastoff reported.
All the same, in that location may exist some grounds to worry about whether AMD is still on that timeline. The company'southward subsequent earnings call left out any mention of RDNA 3 GPUs. Beyond that, AMD's CES 2022 keynote as well failed to affect upcoming graphics cards. This could mean the launch schedule is slipping, or it may be that AMD is planning a refresh of its current RDNA 2 graphics cards, as has been rumored, and talking most RDNA 3 would suck the wind out of the sails of those refreshed cards right when AMD needs them to compete with Nvidia's new RTX 3080 Ti.
As 3 divide graphics cards built on RDNA 3 are expected in the initial line-upward, information technology's as well possible we'll only see a portion of them inside the year, as AMD and Nvidia both have been ho-hum to curl out the lower-cease models after the introduction of the flagship GPUs in their new series.
AMD RDNA 3 price
Nosotros accept little footing for guessing at the prices of AMD'south RDNA 3 graphics card. Logically, the new GPUs — Navi 31, 32, and 33 — will exist the successors to the Navi 21 found in the $999 Radeon RX 6900 XT and $649 RX 6800 XT, Navi 22 found in the $479 RX 6700 XT, and Navi 23 found in the $379 RX 6600 XT, respectively.
Given supply chain and logistics issues over the past two years that are however causing problems, every bit well as TSMC's possible price hikes for flake fabrication, we're sure that we'll be seeing Radeon RX 7000 Series graphics cards that are more expensive than their predecessors.
With that in mind, RedGamingTech has suggested the top-cease model may be set up to be a true brute and could cost over $ii,000.
AMD RDNA 3 specs and performance
In that location's footling more than to go along than whispers and rumors when it comes to the specs of RDNA 3-based graphics cards, only those that we've heard propose some powerful fries that are going to be borrowing a key folio out of AMD'due south Ryzen CPU playbook.
One of the outset things to sympathise near RDNA 3 is that information technology's going to make some other shift away from how some of the components are understood with previous architectures. With RDNA two, the chip independent a number of shader engines, which in turn contained a host of dual compute units loaded with stream processors, texture units, and ray accelerator units.
For RDNA three, the notion of a compute unit seems to have been replaced with workgroup processors which in turn contain stream processors and other elements, and the new models may be merely stuffed. That may be in part because AMD is going with a smaller 5nm manufacturing procedure to fit more into a tighter space and because it'due south going to apply a multi-chip module design — putting multiple GPU chiplets onto a flake instead of one monolithic chip — merely like information technology has washed on Ryzen processors. While this is even so largely rumor and speculation, take the residuum of this equally fifty-fifty less certain until AMD makes an official announcement.
Putting the new pattern into perspective, Navi 31 is believed to accept two chiplets each with 30 workgroups, which incorporate 256 cores (or stream processors) each. That makes for 7,680 cores per chiplet and a total of 15,360 cores for the whole Navi 31 chip — triple the number of stream processors found on the RX 6900 XT.
Regular hardware leaker @Greymon55 on Twitter suggests that the Navi 31 chip connect to 16GB of GDDR6 memory on a 256-bit bus and include 256MB (or 512MB, according to sources for RedGamingTech) of 3D Infinity Cache, boosting operation considerably to make upwards for not using GDDR6X, and run at upwards to 2.5GHz.
Navi 32 would in turn have 40 workgroup processors, 12GB of GDDR6 on a 192-bit motorbus, accept 192MB of 3D Infinity Cache, and run between 2.six and 2.8GHz.
Navi 33 drops down to sixteen workgroup processors, 8GB of GDDR6 on a 128-bit jitney, 64MB of Infinity Cache, and clocks between 2.8 and 3.0GHz.
To put this in some more perspective, Navi 31 would have the previously mentioned 15,360 stream processors, Navi 32 would hit x,240, and Navi 31 would boast 4,096 (inside hitting distance of the number in the Radeon 6900 XT).
While teraflops don't tell us everything about a GPU's performance, it tin be a somewhat useful metric for comparison. And taking the cadre counts and clock speeds, we'd exist expecting Navi 31 to hit a peak 76.8 TFLOPS of FP32 performance, Navi 32 to go 57.three TFLOPS, and Navi 33 to reach 24.6 TFLOPS.
How does that stand up against the latest and greatest cards currently on the market? The Radeon RX 6900 XT boasts 23.04 TFLOPS of FP32 performance and the RTX 3090 offers 35.7 TFLOPS. In other words, RDNA 3 chips could be bringing some serious heat to even Nvidia'due south best, unless the RTX 4090 is as fast as rumored.
We practice expect the new fries to offering a big boost in efficiency. Switching to a small manufacturing process will play a function in that. And AMD's Executive Vice President, Rick Bergman, fifty-fifty before the launch of RDNA 2, said that RDNA three would offer a like leap in performance-per-watt, which should hateful they'll be 50% more than efficient than RDNA 2. That doesn't mean they won't withal be power hungry, though, as RedGamingTech suggests Navi 31 cards should consume about 375W of power but could go as high as 450W.
We'll have to look and see how much of this turns out to be true.
