AMD may have given another hint about their next-gen Radeon RX 7000 series graphics cards based on the RDNA 3 GPU architecture. The hint comes as a cryptic tweet posted by AMD’s Senior Director of Gaming Marketing, Sasa Marinkovic.
Tweet from AMD’s Gaming Marketing Director May Give Us Another Hint on RDNA 3 GPUs Performance for Radeon RX 7000 Cards
Sasa didn’t mention any product in the tweet, but I think we can make a few guesses. First, it seems that this has nothing to do with AMD’s Ryzen 7000 CPUs, as we’ve already gotten a lot of information about the Zen 4 CPUs. The only other gamer-focused product AMD is releasing is their Radeon RX 7000 series, based on the RDNA 3 GPU architecture that was briefly teased on the “Together We Advance_PCs”.

AMD focuses on DIY and PC-friendly graphics card designs and cooling?
So the tweet itself that reads “bigger doesn’t necessarily mean better” could point to the recent NVIDIA GeForce RTX 4090 leaks that showed the card features insanely large and quad-slot cooling solutions. The NVIDIA GeForce RTX 4090 graphics card is expected to be unveiled at GTC 22 in a few days, but AMD has already started shooting their competitor’s next-gen parts, which will be released slightly earlier than their own next-gen solutions. .
The NVIDIA GeForce RTX 4090 custom graphics cards that have leaked so far have a single 16-pin connector (12VPWHR) for up to 600 watts of power and given their higher TGP, they’re going to need some hefty cooling solutions like the one we have. seen a leak recently.
It seems AMD isn’t going down that road, delivering solutions with a more user- and PC-friendly two-slot design. Previous rumors pointed to a slightly larger but still 2.5-slot cooling solution with two 8-pin connectors to boot. So AMD’s Radeon RX 7000 series can come out with a card that not only consumes less power, but also doesn’t require bulky cooling solutions.
Or is this about the GPU dies?
AMD pointed this out a while ago as well, stating that while their cards use a bit more power than RDNA 2, they will be much more efficient than the competition. Keep in mind that the red team is aiming for a 50% perf/watt improvement over RDNA 2 with its new 5nm RDNA 3 GPUs. The other thing Sasa could have pointed out could be the mold size.
AMD’s RDNA 3-powered Radeon RX 7000 series graphics cards will be the first gaming products with an MCM solution. As such, the GPU could move various operations in chiplets like the Infinity Cache, leading to a smaller GPU die. The GPU is designated as a GCD or Graphics Complex Die, while the Infinity Cache and Memory interface are moved to multiple MCDs or Memory-Chiplet Die.
AD102 is 628 mm², Navi31 is 533 mm².

In return, this would lead to a smaller GPU footprint and according to the latest rumor from Kepler_L2, the Navi 31 will measure 533mm2 (308mm2 GCD + 37.5mm2 per MCD), while the NVIDIA AD102 GPU will measure 628mm2 in a single monolithic package. This is a 40% reduction in die size with the same TSMC 5nm process node.
Moreover, it will be easy to compare the transistor density and transistor efficiency of both chips as they both use the same TSMC node instead of the last generation where RDNA 2 and Ampere chips were based on different process technologies from different companies (Samsung 8nm/ TSMC 7nm). At 308mm2, the Navi 31 GPU will be packed more compactly than the Navi 21 GPU which measures 520mm2 and houses 26.8 billion transistors (51.5/mm2).
Anyway, we’re excited about AMD’s RDNA 3 GPUs, bring it on!
AMD managed to close a huge performance gap with its RDNA 2 GPU-based Radeon RX 6000 in the previous generation and even managed to outperform its competitors with excellent efficiency and performance.
The company plans to do it again and this time even better with its first chiplet GPU architecture, the RDNA 3, designed by David Wong and his team for the next generation of RX 7000 series graphics cards. We can’t wait to see the latest GPUs in action later this year.
