Details of AMD’s upcoming Navi 31 GPUs have surfaced, indicating that Team Red is pulling out all the stops for its next-gen graphics cards.
Moore’s Law Is Dead latest video looks at the latest leaks for the Navi 31 and Navi 32 GPUs, with the former supposedly powering future flagship cards from AMD.
For reference, Navi is the main GPU chip that AMD graphics cards are based on. Navi 31 (the most powerful high-end GPUs), Navi 32 (mid-range) and Navi 33 (entry-level and mid-range) will be the backbone of the RDNA 3 architecture, the sequel to the current generation RDNA 2.
Moore’s Law Is Dead (MLID), which is well-connected within the hardware space, begins its presentation by pointing out that AMD is indeed developing Radeon RX 7000 cards with a multi-chip module (MCM). Within AMD, the company refers to 6nm dies as MCDs (Memory Complex Dies), while 5nm dies are known as GCDs (Graphics Complex Dies), according to reports. “very high confidence” sources.
To that end, the Navi 31 GPUs would come with 5nm compute dies, as well as 6nm I/O and Infinity cache dies.
As NotebookCheck explains, this means AMD is taking a stacked 3D approach, reminiscent of the recently released Ryzen 7 5800X3D. This particular aspect of a multi-die design has been spotted before, and with MLID pointing out that it can “100% confirm 3D stacking from all sources”, it looks like AMD is going all out in when it comes to its next-gen GPUs.
Ryzen processors have shaken up the CPU market with a range of efficient chips thanks to its MCM design – a state of affairs that AMD is obviously looking to replicate in terms of the GPU industry, which Nvidia has dominated for years. Moore’s Law Is Dead addresses this scenario by saying that multiple matrices are a “major advantage over Ada Lovelace.”
Next, the Navi 31 cards (NotebookCheck points out that the flagship Radeon RX 7900XT is likely under discussion) will apparently sport 512MB of infinite cache, joined by up to 32GB of VRAM via a 256-bit bus. A total of three variants of this specific configuration are apparently in the works.
As for performance, Moore’s Law Is Dead heard that Navi 31 would provide a 90% to 130% jump over what the Radeon RX 6900XT offers in rasterization.
Radeon RX 7000 vs. RTX 40
Notably, AMD’s next-generation flagship Navi 31 graphics card, “top mainstream,” will boast a power consumption level of between 375 and 450 watts, according to Moore’s Law, it’s dead. “It’s massively more efficient than what Nvidia is doing with Lovelace,” he points out.
Comparatively, power consumption rumors surrounding Nvidia’s RTX 40 GPUs have been a cause for concern, with the latest reports suggesting that Team Green cards could require 600 watts, while some models could even approach the all-time high of 1000 watts. .
It seems that the recent claim that “RDNA 3 will decimate Nvidia in efficiency across the lineup” doesn’t seem like a stretch.
Additionally, we’ve already heard that the overall performance upgrade for RDNA 3 might be bigger for Nvidia’s next-gen cards compared to its predecessors. Yet Team Green isn’t sitting idly by waiting for its main rival to eat away at its market share; it might have a node advantage over AMD, but only time will tell which company will win the next-gen battle.
Elsewhere, MLID has heard that Navi 31 will be compatible with PCIe 5.0 x16. In contrast, Nvidia is reportedly sticking to PCIe 4.0 for its own next-gen GPUs.
Finally, the Navi 31 cards are expected to launch in the fourth quarter of 2022. The final months of this year are apparently still the timeline AMD plans to keep to the release of the Radeon RX 7000 cards, which, if true, would follow the rumored September introduction of the Nvidia RTX 40 series.
As for why AMD chose not to sell its upcoming cards simultaneously with Nvidia products, Moore’s Law Is Dead previously pointed out that RDNA 3 is “a more complex design, really a more ambitious design.” A few more months could see AMD take the “efficiency and performance crown.” Internally, he “knows that this launch has to be perfect”.
Navi 32 joins the fray
Elsewhere, Navi 32 – the mid-range line of next-gen AMD video cards – is also said to be designed with an MCM approach via 5nm GCD and 6nm MCD processes. As noted by NotebookCheck, the series will be developed with 16 GB of VRAM via a 192-bit bus, in addition to 10,000 cores – Navi 31 will allegedly feature up to 15,360 cores (via Wccftech), a threefold increase from compared to 5120 cores. account of the RX 6900.
Breaking with the RDNA 2 rollout schedule, Moore’s Law Is Dead notes that Navi 32 RDNA 3 card GPUs are, according to its most reliable sources, expected to be available in the first half of 2023.
By all accounts, the current plan is to usher in the next generation via entry-level and mid-range Navi 33 graphics cards this year, followed by the flagship and high-end Navi 31 cards, with Navi 32 completing the rollout. next year.
Moore’s Law Is Dead information is not limited to next-gen RDNA 3 GPUs. He even mentioned RDNA 4, which he says will use GDDR7 technology. This reveal isn’t too much of a surprise, but he said “a lot is changing” when it comes to RDNA 4 due to alleged TSMC 3nm issues.
In any case, the well-known insider said that RDNA 4, while it won’t represent quite the same performance boost that RDNA 3 has over RDNA 2, “will borrow a lot from the craziest designs like the MI300 These are elaborate 3D stacking designs that AMD has publicly alluded to.
