![]() ![]() Navi 33 drops down to 16 workgroup processors, 8GB of GDDR6 on a 128-bit bus, 64MB of Infinity Cache, and clocks between 2.8 and 3.0GHz. Navi 32 would in turn have 40 workgroup processors, 12GB of GDDR6 on a 192-bit bus, have 192MB of 3D Infinity Cache, and run between 2.6 and 2.8GHz. A more recent leak from Benchlife has indicated that it could have 20GB, with the rumored RX 7900 XTX model packing a whopping 24GB. Regular hardware leaker 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 performance considerably to make up for not using GDDR6X, and run at up to 2.5GHz. 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. Putting the new design into perspective, Navi 31 is believed to have two chiplets each with 30 workgroups, which contain 256 cores (or stream processors) each. While this is still largely rumor and speculation, take the rest of this as even less certain until AMD makes an official announcement. That may be in part because AMD is going with a smaller 5nm manufacturing process to fit more into a tighter space and because it’s going to use a multi-chip module design - putting multiple GPU chiplets onto a chip instead of one monolithic chip - just like it has done on Ryzen processors. With RDNA 2, the chip contained 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.įor RDNA 3, 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 simply stuffed. One of the first things to understand about RDNA 3 is that it’s going to make another shift away from how some of the components are understood with previous architectures. Other than that, there’s little more to go on than whispers and rumors when it comes to the specs of RDNA 3-based graphics cards, but those that we’ve heard suggest some powerful chips that are going to be borrowing a key page out of AMD’s Ryzen CPU playbook. The information published by AMD states that this performance increase is achieved through a 5nm process node, a refined version of the RDNA 2's adaptive power management technology, rearchitectured compute unit, advanced chiplet packaging, an optimized graphics pipeline, and a new generation of AMD Infinity Cache. According to the Senior Vice President of Engineering, Radeon Technologies Group, David Wang, there will be a 50% performance per watt uplift for next-gen compared to the RDNA 2 chips. (Image credit: AMD) AMD RDNA 3 specs and performanceĪMD confirmed, via Wccftech, that its RDNA 3 chips will have a huge boost in performance. The rumored RX 7900 XTX has no last-gen counterpart, so it will likely have an MSRP close to Nvidia's competing flagship, in the $1,599 range. With that in mind, RedGamingTech has suggested the top-end model may be set up to be a true beast and could cost over $2,000 - however, we think this is overblown. Given supply chain and logistics issues over the past two years that are still causing problems, as well as TSMC’s possible price hikes for chip fabrication, we're sure that we’ll be seeing Radeon RX 7000 Series graphics cards that are more expensive than their predecessors - we'd estimate a price increase of around 10-20% over the previous generation. Logically, the new GPUs - Navi 31, 32, and 33 - will be 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. We have little basis for guessing at the prices of AMD’s RDNA 3 graphics card. Both AMD and Nvidia have become slow at rolling out their lower-end GPUs in each new generation, so don't expect a budget-friendly Radeon RX 7500 to arrive anytime soon. ![]() ![]() We suspect that this will be the RX 7900 XTX, a slightly less powerful RX 7900 XT, and then a somewhat more affordable card - perhaps the 7800 XT or 7700 XT. ![]() Our current expectations are that we'll see three GPUs in the initial lineup, matching Nvidia's three-card announcement earlier this year (even if Team Green did have to hastily 'unlaunch' one of those cards). ![]()
