Here's what to expect from RDNA 3
AMD's new to launch new CPUs and graphics cards later this year, moving their Ryzen and EPYC CPU lineups to Zen 4 core architecture and their high-end Radeon graphics cards to their RDNA 3 gaming architecture.
With RDNA 3, AMD plans to continue increasing the efficiency of their Radeon graphics architecture and gain a leadership position within the GPU market by creating high-end multi-chip graphics cards. According to Moore's Law is Dead, a popular hardware leaker, AMD plans to increase the MSRP pricings of its high-end product offerings while also delivering users a tremendous boost in gaming performance. This change will increase AMD's MSRP pricing while also giving gamers much more performance per dollar spent.
Navi 33 - AMD's First RDNA 3 GPU
Navi 33 is reportedly the first RDNA 3 graphics core that AMD will launch in 2022, a relatively mid-range RDNA 3 design that promises to deliver rasterisation performance that's similar to the company's RX 6900 XT graphics card. This GPU reportedly will feature 8GB of GDDR6 memory and ship with a price tag that is much lower than today's Radeon RX 6900 XT.
With this launch, AMD wants to highlight the performance and pricing offered by RDNA 3, and stress the efficiency of their latest gaming architecture. Some believe that Navi 33 will be used to create a Radeon RX 7700 XT series graphics card in September or October 2022.
Navi 31 - AMD's RDNA 3 Flagship
AMD;s RDNA 3 flagship is Navi 31, and it is set to debut AMD's use of 3D stacked 5nm and 6nm silicon in gaming oriented graphics cards. Moore's Law is Dead has reported that this graphics card should feature a TDP of 375-450 watts depending on the model, and should offer levels of rasterisation performance that is 90-130% faster than AMD's Radeon RX 6900 XT.
If these claims are accurate, AMD will deliver an incredible generational leap in performance with their RDNA 3 flagship. That said, it is currently unknown how RDNA 3 will perform in ray tracing workloads.
AMD's RDNA 3 flagship will reportedly feature 512MB of Infinity Cache and feature a 256-bit memory bus. It has been alleged that AMD has multiple GPU designs planned for their Navi 31 design, one of which could feature a smaller 256MB Infinity Cache.
PCIe 5.0 will reportedly be supported with RDNA 3, lining up well with AMD's Zen 4 CPU architecture and AMD's Ryzen 7000 series products, which will also support PCIe 5.0.
Navi 32 - AMD's other high-end RDNA 3 option
Between Navi 31 and Navi 33 is Navi 32, a GPU design that sits between AMD's two aforementioned GPU designs that's expected to launch in the first half of 2023. This GPU design should also use multiple dies, though it is unknown how this new SKU will perform or how it compares with Navi 31 or Navi 33, aside from the fact that it will be less performant than the former and more performant than the latter.
What we expect from RDNA 3
If the latest rumours regarding RDNA 3 are anything to go by, AMD's RDNA 3 architecture is a design that's focused on efficiency. If Navi 31 can run at 375 watts and achieve 90%-130% more performance than an RX 6900 XT in standard workloads, AMD's power efficiency will have almost doubled within a single generation. Remember, AMD's RX 6900 XT is a 300W graphics card. Delivering around double the RX 6900 XT's performance with a 75W increase in power draw is an incredible achievement.
From the looks of it, AMD's RDNA 3 architecture also doubles down on the company's Infinity Cache technology. AMD's Navi 31 silicon has an Infinity Cache that's reportedly two times larger than the RX 6900 XT's highlighting that AMD sees a lot of additional potential in their Infinity Cache technology. This is especially true given the fact that AMD has not increased the memory bus size of Navi 31 over today's Navi 21 (RX 6800, RX 6800 XT, and RX 6900 XT) silicon.
