AMD’s next-gen graphics cards are coming later this year, and we’ve just witnessed a new batch of rumors regarding when these RDNA 3 models might appear, along with some purported additional design details as well.
Prolific YouTube leaker Moore’s Law is Dead (MLID) spoke about incoming GPUs in his latest video, stating his belief that Navi 31, the high-end chip for RDNA 3 that will likely be led by the RX 7900 XT (note that MLID s ‘expects three different models to be built on Navi 31) is still expected to launch in the fourth quarter, that is, sometime from October to December.
This is supported by an observation of the RX 7900 XT in a changelog, which means software validation has begun on the GPU, as reported by Wccftech. In other words, it’s about fair to suggest that the next-gen flagship graphics card is on track for AMD’s planned launch schedule for the last quarter.
That said, MLID is hinting that while its sources are pretty sure of a Q4 release, there’s a chance Team Red will push it forward a bit, and obviously at this point even AMD still hasn’t not a clear idea of the exact launch month at the moment.
Apparently, more affordable mid-range Navi 33 based GPUs will likely be released just before Navi 31, MLID reckons (there might not be much in it), while graphics cards between these two offerings of top-tier and mid-tier, Navi 32, won’t emerge until 2023 – apparently in the first half of next year.
MLID also once again talks about AMD using a multi-chip module (MCM) strategy – instead of using a single chip, single GPU as usual – reaffirming that the Navi 31 and 32 will go into this way (but the RDNA 3 cards below will be normal GPUs, i.e. monolithic or single-chip).
Apparently Navi 31 is configured to have 5nm 3D stacked compute dies and 6nm I/O dies plus Infinity Cache (meaning they are stacked together), and Navi 32 could also adopt this approach. But even if the latter doesn’t do 3D stacking, it will be a multi-chip affair, at least according to MLID (the two will certainly use 6nm and 5nm chips together, he claims). Of course, all of this should be taken with an appropriate dose of skepticism.
The YouTuber also touches on the prediction of performance gains, repeating previous estimates that Navi 33 should be the equal of AMD’s RX 6900 XT (for rasterization, i.e. traditional rendering as opposed to throwing of rays, at 1080p), with Navi 31 being twice as fast like that (yes, the 7900 XT should double the performance over the 6900 XT).
The performance of the Navi 32 is vaguer because it’s farther out, but MLID estimates it will be at least 20-30% faster than the 6900 XT, maybe even up to 50% (larger portions of condiments are needed with that one, and indeed the idea that Navi 31 could possibly perform even better than mentioned here too).
Analysis: If the rumor is right, RDNA 3 cards should be worth the wait
The launch schedule information reported here is both good news and bad news. It’s good to hear that things are still on track for Navi 31 and 33, but there’s a serious curveball with the theory that Navi 32 might not arrive until much later, possibly until 2023.
If the initial launches of Navi 33 followed by Navi 31 were to arrive in, say, October or November, we could be waiting another six months or so for Navi 32 – given that it’s the first half of 2023, that could theoretically mean June. As these latest arrivals could be the RX 7700 XT or possibly the 7800 XT (MLID seems pretty uncertain on exactly where AMD will split its RDNA 3 lineup), they could be the seriously peppy yet slightly more affordable models that many gamers are looking for. – and they may have to wait for them. If all of this turns out to be true, of course…
MLID seems quite confident in their sources regarding the claim that we will be waiting a bit longer for Navi 32 maps, but only time will tell.
Considering other rumors YouTuber has been circulating lately, RDNA 3 cards should be worth the wait, mind and could (roughly) match Nvidia’s next-gen performance with Lovelace (far from ray tracing, anyway), but do it in a much more efficient way.
While there are rumors that Nvidia’s RTX 4090 could pull 600W of power consumption, speculation around AMD’s next-gen flagship pegs the power consumption at 375W to 450W – which is still a big chunk of power, but obviously much less than Team Green’s peak. GPU dog.
